outputs

Output classes are used to represent the output of a language model call and the output of a chat.

The top container for information is the LLMResult object. LLMResult is used by both chat models and LLMs. This object contains the output of the language model and any additional information that the model provider wants to return.

When invoking models via the standard runnable methods (e.g. invoke, batch, etc.): - Chat models will return AIMessage objects. - LLMs will return regular text strings.

In addition, users can access the raw output of either LLMs or chat models via callbacks. The on_chat_model_end and on_llm_end callbacks will return an LLMResult object containing the generated outputs and any additional information returned by the model provider.

In general, if information is already available in the AIMessage object, it is recommended to access it from there rather than from the LLMResult object.

outputs.generation.Generation	A single text generation output.
outputs.generation.GenerationChunk	Generation chunk, which can be concatenated with other Generation chunks.
