OpenAI announces GPT-6 Astra and puts it on the Plus allowance table

You do not need a new plan to try it, but Plus buys less of Astra than of any other model on that page. OpenAI's docs pricing page lists GPT-6 Astra on ChatGPT Plus at 5 to 45 local messages per five hour period, the lowest allowance in that column at both ends, while every other model listed there starts at 10 or above. The Pro tiers, at $100 and $200 a month, are listed at 25 to 225 and 100 to 900 on the same basis. The spread inside each range is real: OpenAI says simple prompts may take only a fraction of an allowance while large projects and long sessions take significantly more per message. It also says these are estimates rather than fixed limits, and that prompt length alone is not a reliable guide, naming model choice, context, reasoning, tool use, retrieval and caching as the other things that move the number. Our ChatGPT plans table carries the full allowance list with the date it was read.
