Caution: details in this report are highly unusual and unverified.
Chinese outlet 新智元 reports OpenAI has launched GPT-6, codenamed Astra, with Greg Brockman calling it "the model history will remember" — though the official blog post reportedly 404'd briefly. Access is limited to Daybreak Access partners for now.
Key claims:
- Benchmarks: near-perfect scores on FrontierMath Tier4, ARC-AGI3, and ExploitBench (no specifics attached)
- Engineering: internal testers claim it handled PCB auto-placement and routing, drove Blender via MCP + Computer Use, and converted a 2D track map to 3D with a single prompt
- Agent demo: investor Matt Shumer says Astra-driven agents in Unreal Engine spontaneously coordinated to survive, and built a "Manhattan world" in a week; inference tiers run low to max
- Math (unverified): bounded prime gaps cut from 246 to 186; largest prime gap bounds improved by a log log factor, claimed as the first such advance since the 1930s, with Lean-formalized proofs. Noam Brown says its scientific discovery limits haven't been reached
