Together AI SDK Patterns

Quick Guide: Use the together-ai npm package to access 200+ open-source models (Llama, Qwen, Mistral, DeepSeek) via Together AI's fast inference API. The SDK mirrors the OpenAI API shape -- client.chat.completions.create() for chat, client.images.generate() for images, client.embeddings.create() for embeddings. Use response_format: { type: "json_schema" } with Zod-generated schemas for structured output. Function calling uses the same tools parameter shape as OpenAI. You can also use the OpenAI SDK directly by pointing baseURL to https://api.together.xyz/v1.

CRITICAL: Before Using This Skill

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

(You MUST use the together-ai package (import Together from "together-ai") -- NOT the OpenAI SDK -- unless explicitly building an OpenAI-compatible integration)

(You MUST include the JSON schema in BOTH the response_format parameter AND the system prompt when using structured output -- the model needs both)

(You MUST handle errors using Together.APIError and its subclasses -- never use bare catch blocks without error type checking)

(You MUST never hardcode API keys -- always use environment variables via process.env.TOGETHER_API_KEY)
