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

On the new coding-agent benchmark Opus 5.5 leads at 45.5% and Astra follows at 42.8%; on one bug Astra passed 5/5 at low reasoning but only 1/5 at maximum, where it deleted a public API.

A Korean user argues Codex has declined since the $200 plan usage changes, rates GPT-6 Astra below Opus 5.5, and plans to cancel in favor of Grok Bot plus Opus 5.5.

A Codex user claims GPT-6 Astra only drains tokens quickly, says Sol High and Terra perform better in testing, and recommends switching to Sol Medium/High.

A Codex user asks whether GPT-6.1 Terra is genuinely better than GPT-6 Astra at coding or just overhyped.

A video overview of OpenAI's agent ecosystem, from GPT-6 Astra and Sol/Luna models through Agents SDK, Codex, voice APIs, memory and safety frameworks.

A complaint post says Claude Opus 5.5 burns its 5-hour limit in 15–30 minutes, GPT-6 Astra exhausts a week's Codex quota in a day, and Gemini's weekly cap is just as tight.

OpenAI releases GPT-6.1 Terra, claiming computer-use on par with GPT-6 Astra, tasks finished over 3x faster than Astra and Sol, API at $1/$5 per million tokens, limited to ChatGPT Work and Codex on Plus and above.

The author says using Astra/6.1 Sol for Samsung reverse engineering got the account banned because normal technical terms tripped daybreak's content tripwire, while users who obfuscate their wording avoid problems.

Testing bug-hunting with GPT-6 Astra MAX on the $20 Codex plan used 17M tokens over 1.3 hours, about $22.26 of API usage, wiping out the weekly quota and leading the author to estimate only ~$90 of monthly value versus earlier subsidies.

The author used GPT-6 Astra for UI design, Codex plus OpenPencil to build it and Qwen-Image-2.1 Turbo for images to make a book recommendation site, sharing the tools and prompts along with a Codex Plus subscription plug.

After Anthropic banned his Claude Max account six times, the author tried Codex plus GPT-6 Astra for video editing, ended up with an unusable cut and deleted project files, and reflects on over-reliance on one model and model-driven skill gaps.

The author hands all vibe coding to an automated agent, Grok Bot, which drives ChatGPT Astra-6 sessions while Codex does the actual coding.
