OpenAI leaks GPT-6.2 Bell model with 10 trillion parameters, 87% benchcad 2.0 score
The piece reports that OpenAI's next model, codenamed "Bell", was leaked in late October and early November 2026. The leak includes a 10 trillion‑parameter architecture and a reported 87% score on BenchCAD 2.0, a benchmark for 3D physical design.
Key points
- openai leaks gpt-6.2 bell model with 10 trillion parameters
- benchcad 2.0 score jumps from 59% to 87%
- 10,000 ai agents solved navier-stokes problem in 88 hours
The article also notes that 10,000 AI agents collaborated for 88 hours to solve the Navier‑Stokes problem, a long‑standing mathematical challenge. It claims the model may shift OpenAI’s focus toward safety, citing the shelving of GPT‑6.1 for safety reasons.
If the claims hold, the model could move AI from auxiliary tools to full designers in manufacturing, and accelerate autonomous research. The piece warns that the name "Bell" and the ".2" suffix do not necessarily signal a small improvement, echoing past Opus 5.5 lessons.
