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

Pro 200 Codex and Work limits drop from 20x to 10x the Plus tier, existing users receive 62,500 Credits as compensation, and OpenAI also launches Pro 500 and the Astra-powered Dot.

An observation that GPT-6 Astra was everywhere three weeks ago but now barely anyone talks about it.

A post relays an unverified claim that Anthropic engineers share all Claude sessions and can take tasks from each other's queues, and rounds up OpenAI DevDay releases including Dots, ChatGPT Space and GPT-6.1 Sol.

A Japanese thread ranks all 25 announcements from OpenAI DevDay 2026 by interest, including GPT-6.1 Sol, the new Pro 500 plan and Ultrafast speedups.

The author speculates that 6.1 Sol was not trained in seven days but is Astra Minor, originally positioned between Sol and Astra, renamed and price-cut after Opus 5.5 launched.

Aimed at US and A-share traders, the author hints at a stock-trading prompt set that only works well with the GPT-6 Astra model, but the post does not include the prompts themselves.

From GPT-5.6 Sol to GPT-6.1 Sol, releases came thick and fast over two months, with the three major labs resuming launches about a week after calling for a slowdown.

A user canceled their $200/month ChatGPT subscription, saying Claude delivers about ten times the output and is simply better, declaring Astra dead and Opus 5.5 the successor.

OpenAI announced that Dots usage won't count toward eligible plans' usage allowances for the first month, and since Dots are powered by GPT-6 Astra, users speculate it amounts to unlimited Astra calls.

GPT-6 Astra reportedly gains an 8x-speed Ultrafast mode, alongside a Pro 500 plan priced at 84,000 yen per month with a higher token limit.

A critical post says Tibo spent weeks teasing GPT-6.1 Astra without releasing it, Sol iterated too fast, and the $200 tier was cut before a $500 plan was offered.

An analysis says OpenAI's new Ultrafast tier runs on Nvidia GPUs rather than Cerebras, weakening the case that fast inference requires wafer-scale chips, and asks which hardware will power Astra.
