Responses
Warning
This API is experimental and subject to changes based upon our experience as we integrate additional providers. Use with caution.
any_llm.responses(model, input_data, *, provider=None, tools=None, tool_choice=None, max_output_tokens=None, temperature=None, top_p=None, stream=None, api_key=None, api_base=None, api_timeout=None, user=None, instructions=None, max_tool_calls=None, parallel_tool_calls=None, reasoning=None, text=None, **kwargs)
Create a response using the OpenAI-style Responses API.
This follows the OpenAI Responses API shape and returns the aliased
any_llm.types.responses.Response
type. If stream=True
, an iterator of
any_llm.types.responses.ResponseStreamEvent
items is returned.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
model
|
str
|
Model identifier in format 'provider/model' (e.g., 'openai/gpt-4o'). If provider is provided, we assume that the model does not contain the provider name. Otherwise, we assume that the model contains the provider name, like 'openai/gpt-4o'. |
required |
provider
|
str | ProviderName | None
|
Provider name to use for the request. If provided, we assume that the model does not contain the provider name. Otherwise, we assume that the model contains the provider name, like 'openai:gpt-4o'. |
None
|
input_data
|
str | ResponseInputParam
|
The input payload accepted by provider's Responses API. For OpenAI-compatible providers, this is typically a list mixing text, images, and tool instructions, or a dict per OpenAI spec. |
required |
tools
|
list[dict[str, Any] | Callable[..., Any]] | None
|
Optional tools for tool calling (Python callables or OpenAI tool dicts) |
None
|
tool_choice
|
str | dict[str, Any] | None
|
Controls which tools the model can call |
None
|
max_output_tokens
|
int | None
|
Maximum number of output tokens to generate |
None
|
temperature
|
float | None
|
Controls randomness in the response (0.0 to 2.0) |
None
|
top_p
|
float | None
|
Controls diversity via nucleus sampling (0.0 to 1.0) |
None
|
stream
|
bool | None
|
Whether to stream response events |
None
|
api_key
|
str | None
|
API key for the provider |
None
|
api_base

None
|
instructions
|
str | None
|
A system (or developer) message inserted into the model's context. |
None
|
max_tool_calls
|
int | None
|
The maximum number of total calls to built-in tools that can be processed in a response. This maximum number applies across all built-in tool calls, not per individual tool. Any further attempts to call a tool by the model will be ignored. |
None
|
parallel_tool_calls
|
int | None
|
Whether to allow the model to run tool calls in parallel. |
None
|
reasoning
|
Any | None
|
Configuration options for reasoning models. |
None
|
text
|
Any | None
|
Configuration options for a text response from the model. Can be plain text or structured JSON data. |
None

Returns:
Type | Description |
---|---|
Response | Iterator[ResponseStreamEvent]
|
Either a |
Response | Iterator[ResponseStreamEvent]

Raises:
Type | Description |
---|---|
NotImplementedError
