A Promise that resolves to a BaseMessageChunk.
Return a new Runnable that maps a list of inputs to a list of outputs, by calling invoke() with each input.
Create a new runnable sequence that runs each individual runnable in series, piping the output of one runnable into another runnable or runnable-like.
A runnable, function, or object whose values are functions or runnables.

Optional options: Partial<CallOptions>A readable stream that is also an iterable.
Stream all output from a runnable, as reported to the callback system. This includes all inner runs of LLMs, Retrievers, Tools, etc. Output is streamed as Log objects, which include a list of jsonpatch ops that describe how the state of the run has changed in each step, and the final state of the run. The jsonpatch ops can be applied in order to construct state.
Optional options: Partial<CallOptions>Optional streamOptions: Omit<LogStreamCallbackHandlerInput, "autoClose">Default implementation of transform, which buffers input and then calls stream.

Wrapper around OpenAI large language models that use the Chat endpoint.
To use you should have the
openaipackage installed, with theOPENAI_API_KEYenvironment variable set.To use with Azure you should have the
openaipackage installed, with theAZURE_OPENAI_API_KEY,AZURE_OPENAI_API_INSTANCE_NAME,AZURE_OPENAI_API_DEPLOYMENT_NAMEandAZURE_OPENAI_API_VERSIONenvironment variable set.AZURE_OPENAI_BASE_PATHis optional and will overrideAZURE_OPENAI_API_INSTANCE_NAMEif you need to use a custom endpoint.Remarks
Any parameters that are valid to be passed to
openai.createChatCompletioncan be passed through modelKwargs, even if not explicitly available on this class.
