About INT21

We are building self-improving AI systems for the software beneath modern AI. Our first product generates and optimizes low-level GPU software, then proves its work with tests and benchmarks. Today, we are launching INT21: the first company to achieve self-improving AI agent swarms, applied to AI infrastructure. That software has an outsized effect on speed and cost. The first four implementations produced by PTX Kernel Factory are open source today. The product is also entering beta, with early access available at int21.ai.

Blink, speed, charge, stealth, each with its own use. 3 Submit & battle Upload scripts, run training matches against built-in bots, or queue ranked matches.
