Chat Completion Implementation Guidance

via “chat completions with multi-turn conversation management and system prompts”

The official Python library for the together API

Unique: Exposes chat completions as a resource attribute (client.chat.completions.create()) with full type safety via Pydantic ChatCompletion models. Supports tool calling via a tools parameter that accepts OpenAI-compatible tool schemas, enabling function calling without custom serialization.

vs others: Identical API surface to OpenAI SDK (client.chat.completions.create()), making it a drop-in replacement for developers migrating from OpenAI to Together, with the added benefit of supporting multiple open-source models.
