Together AI
One API for the whole open-model universe — Llama, DeepSeek, Qwen and more.
Together AI is a hosted inference cloud for open models: one OpenAI-compatible API serving Llama, DeepSeek, Qwen, Mistral and dozens more, priced from about $0.05 to $9 per million tokens (Llama 3.3 70B around $0.88). The platform itself is commercial, but everything it serves is open-weight — so unlike a closed lab API, your exit is real: the same model you call today can run on your own GPUs tomorrow. A strong bridge for teams not ready to operate vLLM themselves.
What it does well
- +Huge open-model catalog behind one OpenAI-compatible API
- +The models are open — migrating to self-hosting later is realistic
- +Often far cheaper than closed frontier APIs for comparable tasks
Where it falls short
- −A hosted US cloud — your prompts transit their infrastructure
- −Quality/cost varies widely across the catalog; you do the picking
