About
PrimeIntellect is building what it describes as an open superintelligence stack—the infrastructure typically developed internally by frontier AI labs, made available to external teams. Its platform, Lab, unifies compute, environments, evaluations, secure sandboxes, high-performance training, and deployment into a single full-stack system for post-training at frontier scale, supporting workflows from supervised fine-tuning and reinforcement learning to tool use and agent workflows. The company's stated focus is on open-source models trained end to end for long-horizon tasks. Based on its current hiring for a full-stack software engineer, the team is actively expanding its engineering capacity to support this platform.
