I lead product for Claude subscriptions. Today we're renaming our Max plans, and I want to explain why.
When we launched our top plan in April 2025, it had a single limit: 5 hours. It gave you 20x Pro's limit, so we called it Max 20x. When we added weekly limits to Max 20x, we set them to 10x Pro's (the 5-hour limit stayed at 20x).
I get that some new users assumed 20x applied to both limits. We could have done better here, and I'm sorry.
The Ultra plan keeps the weekly limit (10x Pro), but we're removing the 5-hour limit so you can keep building without getting blocked mid-session. This starts today and rolls out in stages. To help prevent fraud and abuse, a temporary limit applies until we've verified your account. You'll get an email when your limit is removed.
We've got more cooking and can't wait to share it. Thanks for building with Claude 🙏
We’re renaming our Max plans:
Max 5x → Max
Max 20x → Ultra
Max is still $100/month, and Ultra is still $200. If you’re a subscriber, there’s nothing you need to do.
We’re also removing the 5-hour limit for verified Ultra accounts, starting today with most existing subscribers. Newer accounts keep a temporary limit until they’re verified, which helps us prevent fraud and abuse. You'll get an email when it's removed.
Weekly limits remain unchanged. View our plans here: https://t.co/niRpyGF5Me
🚨 EXCLUSIVE: OpenAI's next frontier pretrain, internally codenamed "Bullsheet," is being prepped for release as GPT-6.2 Cosmos
Details I can share:
• Cosmos slots in above Astra as the new top tier • Pricing being floated internally: $20 / 1M input, $167 / 1M output (subject to change) • Training wrapped weeks ago. Release was delayed after a faction on the alignment team escalated concerns and leadership agreed to an extended safety eval window
• Early internal evals have it as the strongest model OpenAI has ever trained, by a wide margin, beating every frontier model on every major benchmark 👀
Multiple people familiar with the matter have confirmed. Can't say more yet without burning sources.
Timeline: "soon" 🌌
And of course none of this is true. Almost nobody here knows what's happening inside the labs, so did you really think random accounts are getting top secrets out of multi-billion-dollar companies?
