What is Together AI?

Together AI runs open-weight models on its own GPU fleet and sells access through an OpenAI-compatible API. Beyond serverless inference it offers dedicated endpoints, fine-tuning, and rented GPU clusters for teams that want reserved capacity. The catalogue leans toward open models - Llama, Qwen, DeepSeek, Mistral - including large parameter counts that are impractical to self-host. The differentiator is the combination: you can prototype on serverless endpoints, fine-tune a variant, then move the same workload onto dedicated hardware without changing providers.

  • Pricing is often lower than frontier closed-model APIs

Watch out for

  • Quality ceiling is set by the open models available
  • Busy periods can affect serverless latency
  • Dedicated capacity requires a real spending commitment

FAQ

Which models can I run?

Mostly open-weight models such as Llama, Qwen, Mistral and DeepSeek, including large parameter counts, plus image and embedding models. The mix changes as new open releases appear.

Can I move from serverless to dedicated capacity?

Yes. You can prototype on serverless endpoints, then reserve dedicated GPUs for the same model when traffic justifies it, without changing providers or rewriting your integration.

Is it cheaper than closed-model APIs?

For comparable quality it is often cheaper per token, particularly on larger open models. Heavy sustained usage can be cheaper still on reserved capacity, but idle reservations still bill.
