Six plan and price changes were confirmed this week. The big ones: Claude's $200 plan is now called Ultra and drops the 5-hour limit for verified accounts, and OpenAI doubled Work and Codex usage on ChatGPT Pro. Tibo's 28-day Codex run also ended on Nov 1 with two banked resets.

Confirmed changes

• Claude Max 20x is now Claude Ultra (Oct 30): Anthropic renamed Max 5x to Max ($100) and Max 20x to Ultra ($200). Prices didn't change. Verified Ultra accounts no longer have a 5-hour limit, rolling out from Oct 30 to most existing subscribers; newer accounts keep a temporary limit until verified. Weekly limits are unchanged: Ultra 10x Pro, Max 5x. @claudeai
• ChatGPT Pro: Work and Codex usage doubled (Oct 29): 2x the Work and Codex allowance on Pro 100 and Pro 500, and the Pro 200 cut announced Sep 29 is canceled, so every Pro 200 account is on the higher allowance. Plus is unchanged. Tibo said Business Premium doubles too; the Help Center doesn't cover Business yet. OpenAI Help
• Mistral Large 4 API price cut (Oct 29): input went from $1.36 to $0.70 per 1M tokens, cached input from $0.14 to $0.07 and output from $4.18 to $2.10. Mistral API pricing
• Free API credits on ChatGPT Pro and Business (Oct 28): $100, $200 or $500 a month on the Pro tier of the same price, $20 per paid Business Standard seat and $100 per Premium seat, pooled and capped at $500 per workspace. Credits expire each billing cycle and don't raise ChatGPT or Codex limits. OpenAI docs
• GPT-6.1 Terra in Codex and ChatGPT Work (Oct 26): on Plus, Pro, Business, Enterprise and Edu. OpenAI estimates 35 to 285 local Terra messages per 5 hours on Plus, vs 15 to 160 for GPT-6.1 Sol. Overall plan limits are unchanged. Codex pricing
• GPT-6.1 Terra API (Oct 26): new model at $1 input, $0.05 cached and $5 output per 1M tokens up to 272K, half the price of GPT-6.1 Sol. OpenAI

Also: Mistral deprecated Mistral Medium 3.5 on Oct 31 and points users to Mistral Large 4. It's off the pricing page, and its model page doesn't show a retirement date yet. Our guide

The Codex 28-day run, last week (staff posts)

All from Tibo (@thsottiaux) at OpenAI, for paid Codex and ChatGPT Work users. Times are ET.

• Day 22, Oct 26: GPT-6.1 Terra launched. Post
• Day 23, Oct 27: reset posted at 10:42 PM; Tibo said "And it's done" at 2:29 AM on Oct 28. Post
• Day 25, Oct 29: the Pro limit doubling above. Post
• Day 27, Oct 31: "Banked 1/2", posted at 8:43 PM. Post
• Day 28, Nov 1: "Banked 2/2", posted at 6:27 PM, closing the run. Post

OpenAI hadn't posted that the two banked resets landed when we sent this. Banked resets show in Settings > Usage once they do. Every day of the run: https://limitdigest.com/resets/codex/log/

Dates to watch

• Codex banked reset from Oct 7: our estimate is that it expires around Nov 6 (about 30 days after the grant). OpenAI says expiry varies and shows in Settings > Usage. OpenAI Help
• GPT-5.6 Sol promo rate for purchased Codex credits runs at least through Nov 21, per OpenAI's rate card.

Best value this week

• $20: Claude Pro, about $155 of API usage a week vs about $55 on ChatGPT Plus.
• $200: Claude Ultra, about $1,549 a week vs about $581 on ChatGPT Pro 200.

Both are community measurements via wokey.ai, Nov 2. They're estimates, not vendor numbers. At $100 there's no clear winner. This week's picks
