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

The author tracked Astra's Ultrafast mode over two days and found it usually delivers under 90 TP/s, occasionally 140, far short of the claimed 350 TP/s.

The author says GPT-6 Astra scored 0% on the same football analysis-modeling tasks measured under real conditions on their open-source eval bench.

On the same bug, un-nerfed Astra found and fixed the issue on its own, while Opus 5.5 needed two or three corrections to diagnose it but proactively suggested more ways to prevent recurrence.

A developer asks whether Astra will again swing between total failure and one-shot success instead of solving problems steadily and incrementally.

On VulcanBench Frontier v4's 23 behavior-refactoring tasks, Grok 4.7 leads Opus 5.5, GPT-6 Astra and GPT-6.1 Sol at every tier from Extra-high to Low, but takes longer per task.

A developer says he runs a custom script every 15 minutes to add every app and process to the allowlist just to use Computer Use, and calls on OpenAI to loosen Codex permissions and release 6.1 Astra immediately.

The author says he built a watch-wait-act-ask loop over a weekend using GPT-6 Astra with Jev as the scheduler, cutting his monthly cost from $400 to $8.

A Codex Plus user says that after nearly an hour of testing, 30% of the 5-hour window's quota remained, calling Astra Light's limits very generous.

A rundown of how many days each GPT generation stayed current, from GPT-1's 248 days to GPT-6 Astra's 19 days and GPT-6 Sol's 7, with the author noting the pace keeps accelerating.

kaimcpheeters is streaming GPT-6 Astra taking on Pluto, described as the best StarCraft bot in the world, with a link to the broadcast.

The author gave Claude Opus 5.5 and ChatGPT-6 Astra the same prompt to build a luxury real-estate landing page with 3D parallax and says the difference is clear.

The user says Astra was good but needed babysitting, while Opus 5.5 is the better model with more generous limits, so they are not renewing ChatGPT Pro.
