Together AI
A cloud for running and fine-tuning open models with fast, hosted inference.
Together AI runs a broad set of open-weight models behind a fast, OpenAI-compatible API, and supports fine-tuning and dedicated endpoints. It positions itself as the hosted home for the open-model ecosystem.
For teams that want open models without operating GPUs, it is a direct alternative to self-hosting vLLM.
Where it fits
A fit when you want hosted access to many open models, with fine-tuning, instead of running inference yourself.
Where it does not fit
A hosted service: ruled out when models must run inside your own environment.
