Asynchronously pass a sequence of prompts to a model and return generations.
This method should make use of batched calls for models that expose a batched
API.
Use this method when you want to:
take advantage of batched calls,
need more output from the model than just the top generated value,
are building chains that are agnostic to the underlying language modeltype (e.g., pure text completion models vs chat models).
Parameters

name: str - The name of the runnable that generated the event.
run_id: str - randomly generated ID associated with the given execution ofthe runnable that emitted the event.

llm = ChatOllama(model='llama2')
# Without bind.
chain = (
llm

Asynchronously pass a sequence of prompts to a model and return generations.
This method should make use of batched calls for models that expose a batched

Use this method when you want to:
take advantage of batched calls,
need more output from the model than just the top generated value,
are building chains that are agnostic to the underlying language modeltype (e.g., pure text completion models vs chat models).
Parameters
prompts (List[str]) – List of string prompts.
stop (Optional[List[str]]) – Stop words to use when generating. Model output is cut off at the
first occurrence of any of these substrings.
callbacks (Union[List[BaseCallbackHandler], BaseCallbackManager, None, List[Optional[Union[List[BaseCallbackHandler], BaseCallbackManager]]]]) – Callbacks to pass through. Used for executing additional
functionality, such as logging or streaming, throughout generation.

name: str - The name of the runnable that generated the event.
run_id: str - randomly generated ID associated with the given execution ofthe runnable that emitted the event.

step, and the final state of the run.
The jsonpatch ops can be applied in order to construct state.
Parameters

config (Optional[RunnableConfig]) – The config to use for the runnable.
diff (bool) – Whether to yield diffs between each step, or the current state.
with_streamed_output_list (bool) – Whether to yield the streamed_output list.
include_names (Optional[Sequence[str]]) – Only include logs with these names.
include_types (Optional[Sequence[str]]) – Only include logs with these types.

llm = ChatOllama(model='llama2')
# Without bind.
chain = (
llm
