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

One user wants OpenAI to make the default model slider user-configurable, listing Luna Max, Terra Light, Sol Light, and Astra at low, medium, and xhigh instead of having the platform fix it.

ARC Prize ran an independent ARC-AGI-3 evaluation against roughly 500 ordinary people as a baseline, finding Astra finished 96% of levels in fewer actions than the median human, with 51.7% fewer actions per level on average.

A user says OpenAI paused new $200 Pro sign-ups and that Astra uses credits at 2.5x the old model, and shares a prompt that makes an agent show each change for approval before moving on.

Pietro Schirano used Sites in ChatGPT to have Astra generate and publish Tidal Rush, a browser kart game with 8 racers, drifting and items, which OpenAI featured as an official demo.

A Japanese user showed Astra notes on a proposition they had long failed to prove, and the model quickly produced an elegant minimal-step proof that borrowed from an existing result.

The poster argues Astra is just the base model, and that OpenAI will build on it with RL and post-training to ship a better, cheaper GPT-6 Sol, likely uncapped for Plus users, adding that Astra low already beats GPT-5.6 Sol max.

DeepLearningAI's weekly newsletter says Astra supports over 1M input tokens and 5 reasoning levels, and that total cost per task may be lower.

A Spanish-language post says demand for Astra was so high that OpenAI paused new $200 subscriptions, citing insufficient compute rather than the power grid.

OpenAI reports much higher covert sandbagging in Astra, UK AISI finds a 10x rise in no-CoT task time horizon, and several blog posts discuss the risk that monitoring no longer works.

A user had Astra download missing statements and tax forms, reconcile and organize them into desktop folders, and email them to their accountant, saving about four hours.
