Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments accepts : typing.Optional[typing.Literal["text/event-stream"]] Pass text/event-stream to receive the streamed response as server-sent events. The default is `\n` delimited events. model : typing.Optional[str] Defaults to `command-r-plus-08-2024`. The name of a compatible [Cohere model](https://docs.cohere.com/docs/models) or the ID of a [fine-tuned](https://docs.cohere.com/docs/chat-fine-tuning) model. Compatible Deployments: Cohere Platform, Private Deployments preamble : typing.Optional[str] When specified, the default Cohere preamble will be replaced with the provided one. Preambles are a part of the prompt used to adjust the model's overall behavior and conversation style, and use the `SYSTEM` role. The `SYSTEM` role is also used for the contents of the optional `chat_history=` parameter. When used with the `chat_history=` parameter it adds content throughout a conversation. Conversely, when used with the `preamble=` parameter it adds content at the start of the conversation only. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments chat_history : typing.Optional[typing.Sequence[Message]] A list of previous messages between the user and the model, giving the model conversational context for responding to the user's `message`. Each item represents a single message in the chat history, excluding the current user turn. It has two properties: `role` and `message`. The `role` identifies the sender (`CHATBOT`, `SYSTEM`, or `USER`), while the `message` contains the text content. The chat_history parameter should not be used for `SYSTEM` messages in most cases. Instead, to add a `SYSTEM` role message at the beginning of a conversation, the `preamble` parameter should be used. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments conversation_id : typing.Optional[str] An alternative to `chat_history`. Providing a `conversation_id` creates or resumes a persisted conversation with the specified ID. The ID can be any non empty string. Compatible Deployments: Cohere Platform prompt_truncation : typing.Optional[ChatStreamRequestPromptTruncation] Defaults to `AUTO` when `connectors` are specified and `OFF` in all other cases. Dictates how the prompt will be constructed. With `prompt_truncation` set to "AUTO", some elements from `chat_history` and `documents` will be dropped in an attempt to construct a prompt that fits within the model's context length limit. During this process the order of the documents and chat history will be changed and ranked by relevance. With `prompt_truncation` set to "AUTO_PRESERVE_ORDER", some elements from `chat_history` and `documents` will be dropped in an attempt to construct a prompt that fits within the model's context length limit. During this process the order of the documents and chat history will be preserved as they are inputted into the API. With `prompt_truncation` set to "OFF", no elements will be dropped. If the sum of the inputs exceeds the model's context length limit, a `TooManyTokens` error will be returned. Compatible Deployments: - AUTO: Cohere Platform Only - AUTO_PRESERVE_ORDER: Azure, AWS Sagemaker/Bedrock, Private Deployments connectors : typing.Optional[typing.Sequence[ChatConnector]] Accepts `{"id": "web-search"}`, and/or the `"id"` for a custom [connector](https://docs.cohere.com/docs/connectors), if you've [created](https://docs.cohere.com/v1/docs/creating-and-deploying-a-connector) one. When specified, the model's reply will be enriched with information found by querying each of the connectors (RAG). Compatible Deployments: Cohere Platform search_queries_only : typing.Optional[bool] Defaults to `false`. When `true`, the response will only contain a list of generated search queries, but no search will take place, and no reply from the model to the user's `message` will be generated. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments documents : typing.Optional[typing.Sequence[ChatDocument]] A list of relevant documents that the model can cite to generate a more accurate reply. Each document is a string-string dictionary. Example: ``` [ { "title": "Tall penguins", "text": "Emperor penguins are the tallest." }, { "title": "Penguin habitats", "text": "Emperor penguins only live in Antarctica." }, ] ``` Keys and values from each document will be serialized to a string and passed to the model. The resulting generation will include citations that reference some of these documents. Some suggested keys are "text", "author", and "date". For better generation quality, it is recommended to keep the total word count of the strings in the dictionary to under 300 words. An `id` field (string) can be optionally supplied to identify the document in the citations. This field will not be passed to the model. An `_excludes` field (array of strings) can be optionally supplied to omit some key-value pairs from being shown to the model. The omitted fields will still show up in the citation object. The "_excludes" field will not be passed to the model. See ['Document Mode'](https://docs.cohere.com/docs/retrieval-augmented-generation-rag#document-mode) in the guide for more information. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments citation_quality : typing.Optional[ChatStreamRequestCitationQuality] Defaults to `"accurate"`. Dictates the approach taken to generating citations as part of the RAG flow by allowing the user to specify whether they want `"accurate"` results, `"fast"` results or no results. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments temperature : typing.Optional[float] Defaults to `0.3`. A non-negative float that tunes the degree of randomness in generation. Lower temperatures mean less random generations, and higher temperatures mean more random generations. Randomness can be further maximized by increasing the value of the `p` parameter. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_tokens : typing.Optional[int] The maximum number of tokens the model will generate as part of the response. Note: Setting a low value may result in incomplete generations. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_input_tokens : typing.Optional[int] The maximum number of input tokens to send to the model. If not specified, `max_input_tokens` is the model's context length limit minus a small buffer. Input will be truncated according to the `prompt_truncation` parameter. Compatible Deployments: Cohere Platform k : typing.Optional[int] Ensures only the top `k` most likely tokens are considered for generation at each step. Defaults to `0`, min value of `0`, max value of `500`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments p : typing.Optional[float] Ensures that only the most likely tokens, with total probability mass of `p`, are considered for generation at each step. If both `k` and `p` are enabled, `p` acts after `k`. Defaults to `0.75`. min value of `0.01`, max value of `0.99`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments seed : typing.Optional[int] If specified, the backend will make a best effort to sample tokens deterministically, such that repeated requests with the same seed and parameters should return the same result. However, determinism cannot be totally guaranteed. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments stop_sequences : typing.Optional[typing.Sequence[str]] A list of up to 5 strings that the model will use to stop generation. If the model generates a string that matches any of the strings in the list, it will stop generating tokens and return the generated text up to that point not including the stop sequence. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments frequency_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. The higher the value, the stronger a penalty is applied to previously present tokens, proportional to how many times they have already appeared in the prompt or prior generation. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments presence_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. Similar to `frequency_penalty`, except that this penalty is applied equally to all tokens that have already appeared, regardless of their exact frequencies. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments raw_prompting : typing.Optional[bool] When enabled, the user's prompt will be sent to the model without any pre-processing. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments return_prompt : typing.Optional[bool] The prompt is returned in the `prompt` response field when this is enabled. tools : typing.Optional[typing.Sequence[Tool]] A list of available tools (functions) that the model may suggest invoking before producing a text response. When `tools` is passed (without `tool_results`), the `text` field in the response will be `""` and the `tool_calls` field in the response will be populated with a list of tool calls that need to be made. If no calls need to be made, the `tool_calls` array will be empty. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments tool_results : typing.Optional[typing.Sequence[ToolResult]] A list of results from invoking tools recommended by the model in the previous chat turn. Results are used to produce a text response and will be referenced in citations. When using `tool_results`, `tools` must be passed as well. Each tool_result contains information about how it was invoked, as well as a list of outputs in the form of dictionaries. **Note**: `outputs` must be a list of objects. If your tool returns a single object (eg `{"status": 200}`), make sure to wrap it in a list. ``` tool_results = [ { "call": { "name": , "parameters": { : } }, "outputs": [{ : }] }, ... ] ``` **Note**: Chat calls with `tool_results` should not be included in the Chat history to avoid duplication of the message text. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments force_single_step : typing.Optional[bool] Forces the chat to be single step. Defaults to `false`. response_format : typing.Optional[ResponseFormat] safety_mode : typing.Optional[ChatStreamRequestSafetyMode] Used to select the [safety instruction](https://docs.cohere.com/docs/safety-modes) inserted into the prompt. Defaults to `CONTEXTUAL`. When `NONE` is specified, the safety instruction will be omitted. Safety modes are not yet configurable in combination with `tools`, `tool_results` and `documents` parameters. **Note**: This parameter is only compatible with models [Command R 08-2024](https://docs.cohere.com/docs/command-r#august-2024-release), [Command R+ 08-2024](https://docs.cohere.com/docs/command-r-plus#august-2024-release) and newer. **Note**: `command-r7b-12-2024` only supports `"CONTEXTUAL"` and `"STRICT"` modes.

Randomness can be further maximized by increasing the value of the `p` parameter. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_tokens : typing.Optional[int] The maximum number of tokens the model will generate as part of the response. Note: Setting a low value may result in incomplete generations. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_input_tokens : typing.Optional[int] The maximum number of input tokens to send to the model. If not specified, `max_input_tokens` is the model's context length limit minus a small buffer. Input will be truncated according to the `prompt_truncation` parameter. Compatible Deployments: Cohere Platform k : typing.Optional[int] Ensures only the top `k` most likely tokens are considered for generation at each step. Defaults to `0`, min value of `0`, max value of `500`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments p : typing.Optional[float] Ensures that only the most likely tokens, with total probability mass of `p`, are considered for generation at each step. If both `k` and `p` are enabled, `p` acts after `k`. Defaults to `0.75`. min value of `0.01`, max value of `0.99`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments seed : typing.Optional[int] If specified, the backend will make a best effort to sample tokens deterministically, such that repeated requests with the same seed and parameters should return the same result. However, determinism cannot be totally guaranteed. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments stop_sequences : typing.Optional[typing.Sequence[str]] A list of up to 5 strings that the model will use to stop generation. If the model generates a string that matches any of the strings in the list, it will stop generating tokens and return the generated text up to that point not including the stop sequence. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments frequency_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. The higher the value, the stronger a penalty is applied to previously present tokens, proportional to how many times they have already appeared in the prompt or prior generation. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments presence_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. Similar to `frequency_penalty`, except that this penalty is applied equally to all tokens that have already appeared, regardless of their exact frequencies. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments raw_prompting : typing.Optional[bool] When enabled, the user's prompt will be sent to the model without any pre-processing. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments return_prompt : typing.Optional[bool] The prompt is returned in the `prompt` response field when this is enabled. tools : typing.Optional[typing.Sequence[Tool]] A list of available tools (functions) that the model may suggest invoking before producing a text response. When `tools` is passed (without `tool_results`), the `text` field in the response will be `""` and the `tool_calls` field in the response will be populated with a list of tool calls that need to be made. If no calls need to be made, the `tool_calls` array will be empty. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments tool_results : typing.Optional[typing.Sequence[ToolResult]] A list of results from invoking tools recommended by the model in the previous chat turn. Results are used to produce a text response and will be referenced in citations. When using `tool_results`, `tools` must be passed as well. Each tool_result contains information about how it was invoked, as well as a list of outputs in the form of dictionaries. **Note**: `outputs` must be a list of objects. If your tool returns a single object (eg `{"status": 200}`), make sure to wrap it in a list. ``` tool_results = [ { "call": { "name": , "parameters": { : } }, "outputs": [{ : }] }, ... ] ``` **Note**: Chat calls with `tool_results` should not be included in the Chat history to avoid duplication of the message text. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments force_single_step : typing.Optional[bool] Forces the chat to be single step. Defaults to `false`. response_format : typing.Optional[ResponseFormat] safety_mode : typing.Optional[ChatRequestSafetyMode] Used to select the [safety instruction](https://docs.cohere.com/docs/safety-modes) inserted into the prompt. Defaults to `CONTEXTUAL`. When `NONE` is specified, the safety instruction will be omitted. Safety modes are not yet configurable in combination with `tools`, `tool_results` and `documents` parameters. **Note**: This parameter is only compatible with models [Command R 08-2024](https://docs.cohere.com/docs/command-r#august-2024-release), [Command R+ 08-2024](https://docs.cohere.com/docs/command-r-plus#august-2024-release) and newer. **Note**: `command-r7b-12-2024` only supports `"CONTEXTUAL"` and `"STRICT"` modes.

Defaults to `1`, min value of `1`, max value of `5`. max_tokens : typing.Optional[int] The maximum number of tokens the model will generate as part of the response. Note: Setting a low value may result in incomplete generations. This parameter is off by default, and if it's not specified, the model will continue generating until it emits an EOS completion token. See [BPE Tokens](/bpe-tokens-wiki) for more details. Can only be set to `0` if `return_likelihoods` is set to `ALL` to get the likelihood of the prompt. truncate : typing.Optional[GenerateStreamRequestTruncate] One of `NONE|START|END` to specify how the API will handle inputs longer than the maximum token length. Passing `START` will discard the start of the input. `END` will discard the end of the input. In both cases, input is discarded until the remaining input is exactly the maximum input token length for the model. If `NONE` is selected, when the input exceeds the maximum input token length an error will be returned. temperature : typing.Optional[float] A non-negative float that tunes the degree of randomness in generation. Lower temperatures mean less random generations. See [Temperature](/temperature-wiki) for more details.

The image must be in either `image/jpeg` or `image/png` format and has a maximum size of 5MB. model : typing.Optional[str] Defaults to embed-english-v2.0 The identifier of the model. Smaller "light" models are faster, while larger models will perform better. [Custom models](https://docs.cohere.com/docs/training-custom-models) can also be supplied with their full ID. Available models and corresponding embedding dimensions: * `embed-english-v3.0` 1024 * `embed-multilingual-v3.0` 1024 * `embed-english-light-v3.0` 384 * `embed-multilingual-light-v3.0` 384 * `embed-english-v2.0` 4096 * `embed-english-light-v2.0` 1024 * `embed-multilingual-v2.0` 768 input_type : typing.Optional[EmbedInputType] embedding_types : typing.Optional[typing.Sequence[EmbeddingType]] Specifies the types of embeddings you want to get back. Not required and default is None, which returns the Embed Floats response type. Can be one or more of the following types. * `"float"`: Use this when you want to get back the default float embeddings. Valid for all models. * `"int8"`: Use this when you want to get back signed int8 embeddings. Valid for only v3 models. * `"uint8"`: Use this when you want to get back unsigned int8 embeddings. Valid for only v3 models. * `"binary"`: Use this when you want to get back signed binary embeddings. Valid for only v3 models. * `"ubinary"`: Use this when you want to get back unsigned binary embeddings. Valid for only v3 models. truncate : typing.Optional[EmbedRequestTruncate] One of `NONE|START|END` to specify how the API will handle inputs longer than the maximum token length. Passing `START` will discard the start of the input. `END` will discard the end of the input. In both cases, input is discarded until the remaining input is exactly the maximum input token length for the model. If `NONE` is selected, when the input exceeds the maximum input token length an error will be returned. request_options : typing.Optional[RequestOptions] Request-specific configuration.

The default is `\n` delimited events. model : typing.Optional[str] Defaults to `command-r-plus-08-2024`. The name of a compatible [Cohere model](https://docs.cohere.com/docs/models) or the ID of a [fine-tuned](https://docs.cohere.com/docs/chat-fine-tuning) model. Compatible Deployments: Cohere Platform, Private Deployments preamble : typing.Optional[str] When specified, the default Cohere preamble will be replaced with the provided one. Preambles are a part of the prompt used to adjust the model's overall behavior and conversation style, and use the `SYSTEM` role. The `SYSTEM` role is also used for the contents of the optional `chat_history=` parameter. When used with the `chat_history=` parameter it adds content throughout a conversation. Conversely, when used with the `preamble=` parameter it adds content at the start of the conversation only. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments chat_history : typing.Optional[typing.Sequence[Message]] A list of previous messages between the user and the model, giving the model conversational context for responding to the user's `message`. Each item represents a single message in the chat history, excluding the current user turn. It has two properties: `role` and `message`. The `role` identifies the sender (`CHATBOT`, `SYSTEM`, or `USER`), while the `message` contains the text content. The chat_history parameter should not be used for `SYSTEM` messages in most cases. Instead, to add a `SYSTEM` role message at the beginning of a conversation, the `preamble` parameter should be used. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments conversation_id : typing.Optional[str] An alternative to `chat_history`. Providing a `conversation_id` creates or resumes a persisted conversation with the specified ID. The ID can be any non empty string. Compatible Deployments: Cohere Platform prompt_truncation : typing.Optional[ChatStreamRequestPromptTruncation] Defaults to `AUTO` when `connectors` are specified and `OFF` in all other cases. Dictates how the prompt will be constructed. With `prompt_truncation` set to "AUTO", some elements from `chat_history` and `documents` will be dropped in an attempt to construct a prompt that fits within the model's context length limit. During this process the order of the documents and chat history will be changed and ranked by relevance. With `prompt_truncation` set to "AUTO_PRESERVE_ORDER", some elements from `chat_history` and `documents` will be dropped in an attempt to construct a prompt that fits within the model's context length limit. During this process the order of the documents and chat history will be preserved as they are inputted into the API. With `prompt_truncation` set to "OFF", no elements will be dropped. If the sum of the inputs exceeds the model's context length limit, a `TooManyTokens` error will be returned. Compatible Deployments: - AUTO: Cohere Platform Only - AUTO_PRESERVE_ORDER: Azure, AWS Sagemaker/Bedrock, Private Deployments connectors : typing.Optional[typing.Sequence[ChatConnector]] Accepts `{"id": "web-search"}`, and/or the `"id"` for a custom [connector](https://docs.cohere.com/docs/connectors), if you've [created](https://docs.cohere.com/v1/docs/creating-and-deploying-a-connector) one. When specified, the model's reply will be enriched with information found by querying each of the connectors (RAG). Compatible Deployments: Cohere Platform search_queries_only : typing.Optional[bool] Defaults to `false`. When `true`, the response will only contain a list of generated search queries, but no search will take place, and no reply from the model to the user's `message` will be generated. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments documents : typing.Optional[typing.Sequence[ChatDocument]] A list of relevant documents that the model can cite to generate a more accurate reply. Each document is a string-string dictionary. Example: ``` [ { "title": "Tall penguins", "text": "Emperor penguins are the tallest." }, { "title": "Penguin habitats", "text": "Emperor penguins only live in Antarctica." }, ] ``` Keys and values from each document will be serialized to a string and passed to the model. The resulting generation will include citations that reference some of these documents. Some suggested keys are "text", "author", and "date". For better generation quality, it is recommended to keep the total word count of the strings in the dictionary to under 300 words. An `id` field (string) can be optionally supplied to identify the document in the citations. This field will not be passed to the model. An `_excludes` field (array of strings) can be optionally supplied to omit some key-value pairs from being shown to the model. The omitted fields will still show up in the citation object. The "_excludes" field will not be passed to the model. See ['Document Mode'](https://docs.cohere.com/docs/retrieval-augmented-generation-rag#document-mode) in the guide for more information. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments citation_quality : typing.Optional[ChatStreamRequestCitationQuality] Defaults to `"accurate"`. Dictates the approach taken to generating citations as part of the RAG flow by allowing the user to specify whether they want `"accurate"` results, `"fast"` results or no results. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments temperature : typing.Optional[float] Defaults to `0.3`. A non-negative float that tunes the degree of randomness in generation. Lower temperatures mean less random generations, and higher temperatures mean more random generations. Randomness can be further maximized by increasing the value of the `p` parameter. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_tokens : typing.Optional[int] The maximum number of tokens the model will generate as part of the response. Note: Setting a low value may result in incomplete generations. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_input_tokens : typing.Optional[int] The maximum number of input tokens to send to the model. If not specified, `max_input_tokens` is the model's context length limit minus a small buffer. Input will be truncated according to the `prompt_truncation` parameter. Compatible Deployments: Cohere Platform k : typing.Optional[int] Ensures only the top `k` most likely tokens are considered for generation at each step. Defaults to `0`, min value of `0`, max value of `500`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments p : typing.Optional[float] Ensures that only the most likely tokens, with total probability mass of `p`, are considered for generation at each step. If both `k` and `p` are enabled, `p` acts after `k`. Defaults to `0.75`. min value of `0.01`, max value of `0.99`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments seed : typing.Optional[int] If specified, the backend will make a best effort to sample tokens deterministically, such that repeated requests with the same seed and parameters should return the same result. However, determinism cannot be totally guaranteed. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments stop_sequences : typing.Optional[typing.Sequence[str]] A list of up to 5 strings that the model will use to stop generation. If the model generates a string that matches any of the strings in the list, it will stop generating tokens and return the generated text up to that point not including the stop sequence. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments frequency_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. The higher the value, the stronger a penalty is applied to previously present tokens, proportional to how many times they have already appeared in the prompt or prior generation. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments presence_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. Similar to `frequency_penalty`, except that this penalty is applied equally to all tokens that have already appeared, regardless of their exact frequencies. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments raw_prompting : typing.Optional[bool] When enabled, the user's prompt will be sent to the model without any pre-processing. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments return_prompt : typing.Optional[bool] The prompt is returned in the `prompt` response field when this is enabled. tools : typing.Optional[typing.Sequence[Tool]] A list of available tools (functions) that the model may suggest invoking before producing a text response. When `tools` is passed (without `tool_results`), the `text` field in the response will be `""` and the `tool_calls` field in the response will be populated with a list of tool calls that need to be made. If no calls need to be made, the `tool_calls` array will be empty. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments tool_results : typing.Optional[typing.Sequence[ToolResult]] A list of results from invoking tools recommended by the model in the previous chat turn. Results are used to produce a text response and will be referenced in citations. When using `tool_results`, `tools` must be passed as well. Each tool_result contains information about how it was invoked, as well as a list of outputs in the form of dictionaries. **Note**: `outputs` must be a list of objects. If your tool returns a single object (eg `{"status": 200}`), make sure to wrap it in a list. ``` tool_results = [ { "call": { "name": , "parameters": { : } }, "outputs": [{ : }] }, ... ] ``` **Note**: Chat calls with `tool_results` should not be included in the Chat history to avoid duplication of the message text. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments force_single_step : typing.Optional[bool] Forces the chat to be single step. Defaults to `false`. response_format : typing.Optional[ResponseFormat] safety_mode : typing.Optional[ChatStreamRequestSafetyMode] Used to select the [safety instruction](https://docs.cohere.com/docs/safety-modes) inserted into the prompt. Defaults to `CONTEXTUAL`. When `NONE` is specified, the safety instruction will be omitted. Safety modes are not yet configurable in combination with `tools`, `tool_results` and `documents` parameters. **Note**: This parameter is only compatible with models [Command R 08-2024](https://docs.cohere.com/docs/command-r#august-2024-release), [Command R+ 08-2024](https://docs.cohere.com/docs/command-r-plus#august-2024-release) and newer. **Note**: `command-r7b-12-2024` only supports `"CONTEXTUAL"` and `"STRICT"` modes.

The `role` identifies the sender (`CHATBOT`, `SYSTEM`, or `USER`), while the `message` contains the text content. The chat_history parameter should not be used for `SYSTEM` messages in most cases. Instead, to add a `SYSTEM` role message at the beginning of a conversation, the `preamble` parameter should be used. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments conversation_id : typing.Optional[str] An alternative to `chat_history`. Providing a `conversation_id` creates or resumes a persisted conversation with the specified ID. The ID can be any non empty string. Compatible Deployments: Cohere Platform prompt_truncation : typing.Optional[ChatRequestPromptTruncation] Defaults to `AUTO` when `connectors` are specified and `OFF` in all other cases. Dictates how the prompt will be constructed. With `prompt_truncation` set to "AUTO", some elements from `chat_history` and `documents` will be dropped in an attempt to construct a prompt that fits within the model's context length limit. During this process the order of the documents and chat history will be changed and ranked by relevance. With `prompt_truncation` set to "AUTO_PRESERVE_ORDER", some elements from `chat_history` and `documents` will be dropped in an attempt to construct a prompt that fits within the model's context length limit. During this process the order of the documents and chat history will be preserved as they are inputted into the API. With `prompt_truncation` set to "OFF", no elements will be dropped. If the sum of the inputs exceeds the model's context length limit, a `TooManyTokens` error will be returned. Compatible Deployments: - AUTO: Cohere Platform Only - AUTO_PRESERVE_ORDER: Azure, AWS Sagemaker/Bedrock, Private Deployments connectors : typing.Optional[typing.Sequence[ChatConnector]] Accepts `{"id": "web-search"}`, and/or the `"id"` for a custom [connector](https://docs.cohere.com/docs/connectors), if you've [created](https://docs.cohere.com/v1/docs/creating-and-deploying-a-connector) one. When specified, the model's reply will be enriched with information found by querying each of the connectors (RAG). Compatible Deployments: Cohere Platform search_queries_only : typing.Optional[bool] Defaults to `false`. When `true`, the response will only contain a list of generated search queries, but no search will take place, and no reply from the model to the user's `message` will be generated. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments documents : typing.Optional[typing.Sequence[ChatDocument]] A list of relevant documents that the model can cite to generate a more accurate reply. Each document is a string-string dictionary. Example: ``` [ { "title": "Tall penguins", "text": "Emperor penguins are the tallest." }, { "title": "Penguin habitats", "text": "Emperor penguins only live in Antarctica." }, ] ``` Keys and values from each document will be serialized to a string and passed to the model. The resulting generation will include citations that reference some of these documents. Some suggested keys are "text", "author", and "date". For better generation quality, it is recommended to keep the total word count of the strings in the dictionary to under 300 words. An `id` field (string) can be optionally supplied to identify the document in the citations. This field will not be passed to the model. An `_excludes` field (array of strings) can be optionally supplied to omit some key-value pairs from being shown to the model. The omitted fields will still show up in the citation object. The "_excludes" field will not be passed to the model. See ['Document Mode'](https://docs.cohere.com/docs/retrieval-augmented-generation-rag#document-mode) in the guide for more information. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments citation_quality : typing.Optional[ChatRequestCitationQuality] Defaults to `"accurate"`. Dictates the approach taken to generating citations as part of the RAG flow by allowing the user to specify whether they want `"accurate"` results, `"fast"` results or no results. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments temperature : typing.Optional[float] Defaults to `0.3`. A non-negative float that tunes the degree of randomness in generation. Lower temperatures mean less random generations, and higher temperatures mean more random generations. Randomness can be further maximized by increasing the value of the `p` parameter. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_tokens : typing.Optional[int] The maximum number of tokens the model will generate as part of the response. Note: Setting a low value may result in incomplete generations. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments max_input_tokens : typing.Optional[int] The maximum number of input tokens to send to the model. If not specified, `max_input_tokens` is the model's context length limit minus a small buffer. Input will be truncated according to the `prompt_truncation` parameter. Compatible Deployments: Cohere Platform k : typing.Optional[int] Ensures only the top `k` most likely tokens are considered for generation at each step. Defaults to `0`, min value of `0`, max value of `500`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments p : typing.Optional[float] Ensures that only the most likely tokens, with total probability mass of `p`, are considered for generation at each step. If both `k` and `p` are enabled, `p` acts after `k`. Defaults to `0.75`. min value of `0.01`, max value of `0.99`. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments seed : typing.Optional[int] If specified, the backend will make a best effort to sample tokens deterministically, such that repeated requests with the same seed and parameters should return the same result. However, determinism cannot be totally guaranteed. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments stop_sequences : typing.Optional[typing.Sequence[str]] A list of up to 5 strings that the model will use to stop generation. If the model generates a string that matches any of the strings in the list, it will stop generating tokens and return the generated text up to that point not including the stop sequence. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments frequency_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. The higher the value, the stronger a penalty is applied to previously present tokens, proportional to how many times they have already appeared in the prompt or prior generation. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments presence_penalty : typing.Optional[float] Defaults to `0.0`, min value of `0.0`, max value of `1.0`. Used to reduce repetitiveness of generated tokens. Similar to `frequency_penalty`, except that this penalty is applied equally to all tokens that have already appeared, regardless of their exact frequencies. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments raw_prompting : typing.Optional[bool] When enabled, the user's prompt will be sent to the model without any pre-processing. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments return_prompt : typing.Optional[bool] The prompt is returned in the `prompt` response field when this is enabled. tools : typing.Optional[typing.Sequence[Tool]] A list of available tools (functions) that the model may suggest invoking before producing a text response. When `tools` is passed (without `tool_results`), the `text` field in the response will be `""` and the `tool_calls` field in the response will be populated with a list of tool calls that need to be made. If no calls need to be made, the `tool_calls` array will be empty. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments tool_results : typing.Optional[typing.Sequence[ToolResult]] A list of results from invoking tools recommended by the model in the previous chat turn. Results are used to produce a text response and will be referenced in citations. When using `tool_results`, `tools` must be passed as well. Each tool_result contains information about how it was invoked, as well as a list of outputs in the form of dictionaries. **Note**: `outputs` must be a list of objects. If your tool returns a single object (eg `{"status": 200}`), make sure to wrap it in a list. ``` tool_results = [ { "call": { "name": , "parameters": { : } }, "outputs": [{ : }] }, ... ] ``` **Note**: Chat calls with `tool_results` should not be included in the Chat history to avoid duplication of the message text. Compatible Deployments: Cohere Platform, Azure, AWS Sagemaker/Bedrock, Private Deployments force_single_step : typing.Optional[bool] Forces the chat to be single step. Defaults to `false`. response_format : typing.Optional[ResponseFormat] safety_mode : typing.Optional[ChatRequestSafetyMode] Used to select the [safety instruction](https://docs.cohere.com/docs/safety-modes) inserted into the prompt. Defaults to `CONTEXTUAL`. When `NONE` is specified, the safety instruction will be omitted. Safety modes are not yet configurable in combination with `tools`, `tool_results` and `documents` parameters. **Note**: This parameter is only compatible with models [Command R 08-2024](https://docs.cohere.com/docs/command-r#august-2024-release), [Command R+ 08-2024](https://docs.cohere.com/docs/command-r-plus#august-2024-release) and newer. **Note**: `command-r7b-12-2024` only supports `"CONTEXTUAL"` and `"STRICT"` modes.
