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

A user complains that Astra ultrafast on the $500 plan does not live up to its name and questions whether the money is worth it.

A chart ranks Opus 5.5, GPT-6 Astra and GPT-6.1 Sol by aaii score, comparing each reasoning level's score and cost per task, colored by best value.

A user says running GPT-6 Astra Ultrafast on the $500 ChatGPT Pro Max plan used up the entire weekly quota in under half an hour, with a screenshot showing 0% left.

A Japanese list walks through all 20 DevDay announcements: always-on Dots agents, GPT-6.1 Sol, 8x faster Astra, reusable Codex cloud environments and security scanning, and the $500 Pro plan.

The author argues Dots lets no-code users plug an always-on cloud agent into any task and says the launch threatens many startups.

A Japanese developer walks through the 20+ announcements from DevDay 2026, highlighting the GPT-6 Astra-powered dots, Sol-6.1 and Codex/API upgrades, and says the event offered few surprises.

The author lays out a Codex setup where the main session and three subagents run 6.1 Sol (high/medium) and Astra does an independent xhigh review only before major changes, with a ready-to-paste config prompt.

The post says Sol is usable day to day and far cheaper than Astra, with solid scores on terminal-bench 4.0 and DeepSWE.

OpenAI announced dots, an always-on agent built on GPT-6 Astra that runs tasks in the background 24/7, learns as it is used, can start work on its own, and has configurable scope.

A developer lists an ideal Dev Day lineup — GPT 6.5 Astra, Cerebras at 1500 tok/s, a new open-source model, GPT Bel 6.5 and doubled limits on all plans — and calls OpenAI's showing a generational fumble.

A $20-plan subscriber says Sol matches Sonnet 5.5 at one-tenth the cost and is five times cheaper than Astra, and plans to test it.

Dots runs on GPT-6 Astra and can connect to calendars and messengers inside ChatGPT, running tasks in the background and sending results; GPT-6.1 Sol also launched at one-fifth the price of the flagship.
