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

The author argues dots' biggest advantage is living inside ChatGPT with Astra and memory behind it, but cramming Codex, Work and dots into ChatGPT makes it hard for ordinary users to get started.

The author says Astra-Medium noticed a formula didn't add up, and together they traced it to an error in the official documentation that may cause many models to underestimate runoff by 15-25%.

A monthly budget setup that pairs Claude or Codex with OpenCode, using GPT-6 Astra or Opus 5.5 as the orchestrator and DeepSeek as the implementer, claimed to yield around 2 billion tokens a month without hitting limits.

On the Code Arena WebDev leaderboard, GPT-6.1 Sol (Max) scores 1759 points for third place, 30 points behind GPT-6 Astra at 80% lower blended token cost.

Researchers who re-audited mitigations for their reasoning extraction attack say reasoning can still be extracted from Astra and Sol-6.1 through third-party API providers, and they have disclosed the findings to OpenAI and Anthropic.

In an update to the "stolen thoughts" series, the authors claim they again extracted raw reasoning traces, this time including those of GPT-6 Astra, with a PDF for details.

A new benchmark tests frontier LLMs on 20 realistic 3D production workflows; GPT-6 Astra leads overall, while Claude Opus 5.5 wins modeling and cloth simulation.

A user who has used both ChatGPT and Claude for years says Astra's recent quality makes them feel Sam Altman has lost the AI race.

Mercor's tests show GPT-6.1 Sol scoring 60.0% Pass@1 on APEX-Agents, 4.7 points behind Astra, beating Astra in investment banking at one-fifth of its token price.

The author gave Claude Opus 5.5 Max and GPT-6 Astra High the same prompt, "imagine the future of humanity," and had each generate a 30-second video for a side-by-side comparison.

On the same prompt, Opus 5.5 got it right on the first try for $14.30, while Astra needed two follow-up prompts and cost $32.88 in total.

A reply argues that games are essentially math and data, and that GPT-6 Astra and Claude 5.5 are strong in both, so they can be used to mod games.
