Fireworks Serverless recently retired mixtral-8x-7b-instruct, which was the default model for ChatFireworks.
langchain-fireworks 0.3 removes the default model altogether, so that the model must be explicitly specified on init:
ChatFireworks(model="accounts/fireworks/models/llama-v3p1-70b-instruct") # for exampleThis release also sets a null default for temperature, which previously defaulted to 0.0. This parameter will no longer be included in request payloads unless it is explicitly provided.
