Two plan and price changes were confirmed this week, and OpenAI kept resetting Codex limits: five resets in seven days as Tibo's 28-day run heads into its last week.

Confirmed changes

• GitHub Copilot Free (Oct 21): GitHub no longer lists a fixed 50 chat requests. The plans page now says 2,000 completions a month with limited chat and agent usage. Paid plan prices didn't change. GitHub Copilot plans
• Mistral Large 4 API (Oct 21): the sale price ended. Input went from $0.68 to $1.36 per 1M tokens, cached input from $0.07 to $0.14 and output from $2.09 to $4.18. Mistral API pricing

The run ends Nov 1. Every day, reset or not: https://limitdigest.com/resets/codex/log/

Dates to watch

• ChatGPT Pro 200 grandfathered allowance ends Oct 29: if you had Pro 200 between Sept 22 and 10 AM PT on Sept 29, you keep the old, larger allowance through Oct 29. After that it drops to the lower allowance, still at $200 a month. OpenAI Help
• DeepSeek Search and Fetch billing starts Oct 31 at 12 PM ET (Nov 1, midnight Beijing time). Search and fetch calls from DeepSeek Harness, Claude Code or Codex on the DeepSeek API are free until then, then $0.75 per 1,000 requests. DeepSeek pricing
• 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 at $20 this week

Claude Pro again: about $170 of API usage a week vs about $58 on ChatGPT Plus (Codex), based on community measurements via wokey.ai, Oct 19. These are estimates, not vendor numbers. At $100 and $200 there is no clear winner. This week's picks

• Codex credits: what they cost and when to buy them: every Codex credit rate is 25x the model's API price, so a credit is worth about $0.04 of API usage by our math. If you'd top up more than about $80 a month, Pro 100 is the better deal.
• Claude extra usage: what it costs and when Max is cheaper
• Codex Pro 100 vs Claude Code Max 5x: the two $100 coding plans side by side.
• GPT-6 Astra vs Claude Opus 5.5: price, coding and limits.
• ChatGPT usage limit reached: what to do
