Together AI
Inference-as-a-service for open-weights models. Fastest Llama, DeepSeek, and Mixtral access.
By C.W. Jameson · Published 19 May 2026 · Last reviewed 19 May 2026
Together AI is the inference service that open-weights model operators reach for when latency matters. They maintain optimised GPU clusters for the most-demanded open models and consistently offer lower latency than self-hosting on equivalent hardware. The business model is pure infrastructure: no proprietary models, no lock-in, just fast execution of whatever the community is running this week.
