The Future Is Self-Improving. AI999X Labs builds tiny, fast scientific AI that runs on anyone's device, anywhere, with no internet and no big tech in the middle: ONNX on any CPU, Safetensors for research and fine-tuning. Next: models that improve themselves and do their own research, fully offline and anonymous.
39 scientific models · 3,438 capabilities · 7 fields — and growing. Each is a compact model that answers questions in its field — in plain English or as a typed call — with exact answers, steps, units and LaTeX, fully offline on any CPU, and says so when it cannot answer instead of guessing.
