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

A user says they cancelled $300/month SuperGrok Heavy for the $200 ChatGPT Pro plan, citing GPT-6 Astra as the world's second-best model, unlimited Chat and Dot usage, and stronger voice and image generation.

Peter Yang updates his review of four personal agents, noting Muse Wonder is good but Opus/Astra is better.

Citing an original post, the author says GPT-6 Astra accepts 88.3% of reasonable counterarguments and is open to discussion, while Grok's built-in first-principles thinking makes it even more conversational.

The poster predicts a big release week with Claude Fable 5.5, OpenAI 6.1 Astra or Ben, and Grok 4.8 or 5, and asks which one people are most excited about.

The author treats LLMs as information retrievers and rates Opus 5.5, Grok 4.7, GLM, DeepSeek, Kimi, Qwen, Nemotron, Gemini, plus OpenAI's Luna, Astra and Sol, calling Astra great but saying GPT-6.1 Sol doesn't click for them.

The author says they hand coding to SWE-2 and Grok 4.7, arguing that insisting on frontier models like Opus 5.5, Fable 5.1 or GPT-6 Astra costs more in price and limits.

A comparison of which model tier OpenAI, Anthropic, SpaceXAI and Google offer at the same subscription price, with a jab that Google's $20 Pro plan only gives Gemini 3.8 Flash.

The author breaks down about $175 a month in AI and software subscriptions, mainly ChatGPT Pro for GPT-6 Astra and OpenCode Go, with X payouts covering the cost.

The author uses Grok bots for automated trading, price comparison, research and community management, but still relies on Astra Ultra and Claude for complex deep discussions and development.

Grok 4.7 ranks first on the Harvey legal benchmark, ahead of Claude Opus 5.5, GPT-6 Astra and Muse Spark 1.3.

Under a new method requiring answers free of material hallucinations, Grok 4.7 leads at 9.4%, with GPT-6 Astra third at 8.6% and only 4 material hallucinations across 120 tasks.

A robotics data generation team says it will plug Grok 4.7 into its pipeline and compare it with OpenAI's GPT-6 Astra on success rate, accuracy and cost per task.
