Cohere
Parameter reference for the Cohere model class, covering request, client, and retry settings.
The Cohere model provides access to Cohere's language models.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
id | str | "command-a-03-2025" | The ID of the Cohere model to use |
name | str | "cohere" | The name of the model |
provider | str | "Cohere" | The provider of the model |
api_key | Optional[str] | None | The API key for Cohere (defaults to CO_API_KEY env var) |
max_tokens | Optional[int] | None | Maximum number of tokens to generate |
temperature | Optional[float] | None | Controls randomness in the model's output |
top_p | Optional[float] | None | Controls diversity via nucleus sampling (0.01 to 0.99) |
top_k | Optional[int] | None | Controls diversity via top-k sampling |
seed | Optional[int] | None | Random seed for best-effort repeatability. Identical requests can still differ |
frequency_penalty | Optional[float] | None | Reduces repetition by penalizing frequent tokens (0.0 to 1.0) |
presence_penalty | Optional[float] | None | Reduces repetition by penalizing present tokens (0.0 to 1.0) |
logprobs | Optional[bool] | None | Return log probabilities of the output tokens |
strict_tools | bool | False | Enforce strict tool schemas in requests |
add_chat_history | bool | False | Currently unused. Request construction does not read this value |
request_params | Optional[Dict[str, Any]] | None | Additional parameters to include in the request |
client_params | Optional[Dict[str, Any]] | None | Currently unused. Client construction does not merge this mapping |
http_client | Optional[Union[httpx.Client, httpx.AsyncClient]] | None | Custom HTTP client for requests |
client | Optional[CohereClient] | None | Pre-configured Cohere client |
async_client | Optional[CohereAsyncClient] | None | Pre-configured async Cohere client |
model_type | ModelType | ModelType.MODEL | Functional role of this model (e.g. MODEL, OUTPUT_MODEL, PARSER_MODEL). Set by the agent |
supports_native_structured_outputs | bool | False | Whether the model supports structured outputs natively |
supports_json_schema_outputs | bool | False | Whether the model uses JSON schema for structured outputs |
system_prompt | Optional[str] | None | System prompt from the model added to the agent |
instructions | Optional[List[str]] | None | Instructions from the model added to the agent |
tool_message_role | str | "tool" | Role of tool messages |
assistant_message_role | str | "assistant" | Role of assistant messages |
cache_response | bool | False | Cache model responses to avoid redundant API calls during development |
cache_ttl | Optional[int] | None | Time-to-live for cached responses, in seconds |
cache_dir | Optional[str] | None | Directory for the response cache. Defaults to ~/.agno/cache/model_responses |
retries | int | 0 | Number of retries to attempt before raising a ModelProviderError |
delay_between_retries | int | 1 | Delay between retries, in seconds |
exponential_backoff | bool | False | If True, the delay between retries is doubled each time |
retry_with_guidance | bool | True | Retry a failed model invocation once with a guidance message appended |
retry_with_guidance_limit | int | 1 | Number of times to retry the model invocation with guidance |
add_chat_history does not affect message construction, and client_params is not passed to either Cohere client.
