Together AI Client

[marklysze]

This is a Together AI Client that provides a way to use the Together AI cloud inference service, which provides options to use many LLMs, such as Google's Gemma, Meta's Llama 2/3, Qwen, Mistral.AI's Mistral, and Mixtral, NousResearch's Hermes models.

This client supports text generation and function/tool calling (when using certain models as noted by Together AI).

Token costs are also implemented.

Will be used in the upcoming blog post #2965.
