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

The author shows a fully automated trading architecture that lets GPT-6 Astra place orders with $20,000 in real crypto markets, with a video explaining how to build it.

Given the same prompt, Sonnet 5.5, Opus 5.5 and GPT-6 Astra each built a 3D planet, and the author asks whether Sonnet at max effort now beats Opus.

A Claude user says Sonnet 5.5 is on par with or better than GPT-6 Astra at 3D and promises a formal comparison test.

A Brazilian developer poses a hypothetical: if OpenAI released an Astra 6.1 that consumed at the same tier as Opus 5.5, would you choose Claude Code or Codex?

The poster says Opus 5.5 and Sonnet 5.5 have made Astra and Sol look useless, and predicts Anthropic's upcoming models will keep pressuring OpenAI.

Agent Arena measured GPT-6 Luna across 8,000 real agent sessions, finding a +1.6% net improvement and 23rd place, with a median cost of $0.05 per task, 98% cheaper than Astra.

ValsAI ran GPT-6 Astra and Opus 5.5 at every reasoning level on its MysteryMechanism benchmark, finding longer thinking improves accuracy but can cost up to 20x more.

The new World of AI Bench leaderboard puts Opus 5.5, GPT-6 Astra, Sonnet 5.5 and GPT-6 Sol in the top four, with the author noting Sonnet 5.5 burns more tokens to edge Sol by 0.4 points.

Using the same prompt on a 3D Cerebras chip benchmark, the author compares Astra Ultra and Sonnet 5.5 XHigh and finds both Anthropic and OpenAI clearly ahead of the rest on efficiency, quality and cost.

A user notes that Astra made a grammatical error answering a question in Polish, and jokes that AGI is still far off.

A joking post lists 20 imagined OpenAI announcements, from Astra 6.1, Sol, Luna and a $500 plan to OpenAI acquiring Google.

A poster says OpenAI will reveal its always-on agent, "o" or "Aeon", tomorrow, and expects Astra to get an update to show it still leads.
