Prime Intellect

Prime Intellect is an integrated platform for training, deploying and improving custom AI models. Its stack combines GPU compute, reinforcement learning environments, hosted evaluations, hosted training, inference and sandboxes, all reachable through a command line tool installed with pip install prime. The vendor describes its goal as an open superintelligence stack in which customers own their own models. The platform is built for AI labs, researchers and engineering teams that want to post train agents on their own tasks. The Environment Hub offers more than 2,500 community RL environments, built on the open source Verifiers library, that can be created, developed, evaluated and pushed from one CLI loop. Hosted evaluations benchmark models across more than 100 open source models without infrastructure setup, and a public leaderboard is available. Hosted Training runs managed training workflows with visibility and control and support from the applied research team. Inference serves Prime hosted models, starting with GLM 5.3, plus gateway access to third party models through one OpenAI compatible API. Compute is priced per hour per GPU, with the home page listing on demand single node and multi node capacity across several GPU types, spot pricing on some, and reserved clusters available on request. Rates vary by GPU model and are shown on the site. The vendor offers a book a call option for larger engagements, and a status page tracks the platform, API, training, inference, evaluations and sandboxes.
