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

Redis creator antirez had Astra rework the safety argument for the original RedLock algorithm, assuming clients finish work before the lock auto-expires and clocks are imprecise but error-bounded, calling it an interesting start.

The author argues Astra is unusually sensitive to stale rules in skills and AGENTS.md, that constraints written for weaker models overconstrain it and burn context, and that input above 272K tokens is repriced at 2x.

Tibo announced that GPT-6 Astra and 6.1 Sol on ChatGPT subscriptions get a default speed boost from 30 to 50 tokens per second, effective within two hours and also covering third-party tools that sign in with ChatGPT.

A video demo shows a 3D airport scene generated with Astra and Opus 5.5, presented as a side-by-side showcase of model output.

Codex and ChatGPT are now faster across the board, rising from 30 TPS to 50 TPS, with no quota reset today.

On the first day of the 28-day challenge, output speed for both models rose noticeably, and the author jokes that OpenAI is no longer at risk of going bankrupt.

A user says subscription speeds are up by half by default, and that this is only day one of a 28-day improvement plan.

A team member says inference for GPT-6 Astra and 6.1 Sol has been optimized to be 50% faster, rolling out across ChatGPT sign-in and plans over the next few hours.

The poster says they will accept the speed boost in place of a quota reset and is waiting to see what the team ships tomorrow.

The user says GPT-6 Astra and 6.1 Sol got roughly a 50% speed boost to about 50 tokens/s, still only half of Opus 5.5's speed, and thinks a quota reset is deserved.

The author built a visual concept where Astra explores options and Opus checks and repairs them, with 24 routes that rewind to the last useful fork when one hits a dead end, discarding bad branches while keeping useful work.

A Japanese user notes that on day one OpenAI made Astra and GPT-6.1 Sol 1.5x faster for all subscription users, and wonders whether Ultra Fast gets the same boost.
