Summary
Matthew Berman’s livestream captures the GPT-6 Astra launch in real time, walking through benchmark scores, pricing, and a large collection of live demos. Astra achieves near-saturation on ARC AGI 3 (99.9%), Frontier Math Tier 4, and Terminal Bench 4.0 (57.9% at lower API cost than Claude Fable 5.1’s maximum-effort score of 55.8% at $950). Berman also notes Astra’s contributions to prime number research and covers the rollout timeline for paid OpenAI users.
The demo portion of the stream is extensive: a Fall Guys-style multiplayer game built from a single prompt, a walkable 3D ASCII-character city called After Hours, and a seven-biome interactive environment comparable to outputs from GLM 5.3 and Fable 5.1. A playable Fall Guys clone—polished with a second prompt covering camera controls and platform physics—runs live in the browser during the stream. All demos are hosted via Here.now and accessible to viewers.
As a livestream, the format is more conversational and audience-interactive than Berman’s edited review of the same model, with live Q&A on availability, benchmark methodology, and comparisons against GPT-5.6 Soul and Claude Fable 5.1 across coding, math, and agent benchmarks.
