GPT-6 Astra in Practice: Tests, Use Cases, and Feedback

A user estimates that running Astra for about three hours per problem to solve decade-old math questions costs roughly $800 at API prices, which would fit inside a $500 monthly subscription.

The author used the unreal-home-wizard skill with Codex (GPT-6 Astra and Luna) and Blender to turn a single room image into a walkable Unity 3D scene, then added a sliding door and a connected second room.

The author compares community reactions to new OpenAI and Anthropic model releases, arguing that discussion around GPT-6 Astra was noticeably quieter than for its competitor.

River claims its API can fine-tune open-weight models to outperform GPT-6 Astra and Claude Opus 5.5 on custom tasks at less than 1% of the cost.

A researcher used Astra to produce a cleaner 2.5-page version of the 2005 proof that an edit distance embedding into l1 is optimal, checking steps in Lean and still seeking peer review.

SEAR is a new benchmark and framework for evaluating how LLM agents self-evolve on robots, testing 7 frontier models on 330 simulation tasks, 2 physics engines and real hardware; Astra did best at watching and correcting moves live, while Fable did best at writing its own code tools first.

The author used GPT-6 Astra with JavaScript, Canvas and WebGL to recreate a game scene, spending roughly 1.5 weekly limits and 20 hours of work, and says the result is not a 100% perfect clone.

The author lists eight GitHub repos, including OpenAI Agents SDK, Mem0, Graphiti, Composio and E2B, arguing that the model sets the ceiling while the architecture decides whether the system actually works.

Scale AI released Humanity's Sixth Sense, a benchmark of 522 open-ended image and video tasks, where the strongest model, GPT-6 Astra, scores 53.6% and the median model just 30.9%, far behind humans at 93.1%.

A joke comparison: Astra refuses outright, Opus 5.5 does it while agonizing over ethics, and GLM-5.3 jumps straight to MITM.

A user spotted GPT-6 finally showing up in ChatGPT's model list, but the label only says GPT-6 Thinking, so it's unclear whether it's Sol or Astra.

On day three of the rollout, OpenAI says combined active users across Codex and ChatGPT Work reached a new high of 40M and is loading a banked reset into all paid accounts.
