Prime Intellect

Prime Intellect offers an integrated stack for training, evaluating and serving your own AI models, with GPU compute, reinforcement learning environments, hosted training and an OpenAI-compatible inference API. It targets teams post-training agents for their own tasks.

The Prime CLI turns any task into an RL environment built on the open-source Verifiers library, and the Hub hosts more than 2,500 community environments. Hosted evaluations benchmark 100+ open models with a public leaderboard, and managed training runs come with support from the company's research team.

For inference, Prime hosts models such as GLM-5.3 and routes to third-party models through a gateway behind one API. The company is known for open research on decentralised training and is backed by Founders Fund, NVIDIA and individual researchers including Andrej Karpathy.
