Google−Free Gemini users limited to Flash-Lite
Google removed Flash and Pro models from the free Gemini app tier from October 9, 2026, leaving Flash-Lite. AI Plus keeps Flash but not Pro; AI Pro is the cheapest plan with all three models.
OpenAI±New Pro 500 tier; Pro 200 allowances changed
OpenAI added a $500/month Pro plan with the highest included usage of the Pro plans and brought back Pro 200 at an unchanged price with changed included allowances.
Anthropic−Claude Code weekly limits settle 25% above old baseline
The temporary 50% weekly boost ended and was replaced on September 14 by a permanent 25% increase over the original allowance, about 17% less than during the promotion. Anthropic first called it a raise, then posted a clarification acknowledging the 17% reduction.
Google±Gemini Notebook switches to compute-based limits
Daily feature-generation counts are replaced by compute-based limits that refresh every five hours, rolling out from September 2. A status line now warns when you are near the limit and shows when it resets, and Studio outputs show an expected-cost indicator.
OpenAI−5-hour Codex limit returns for ChatGPT Plus
OpenAI brought back the rolling 5-hour limit for Plus users of Codex and ChatGPT Work, in full effect August 25, and reset weekly limits that day. The 5-hour limit stays off for both Pro tiers for the coming months.
OpenAI+OpenAI temporarily drops the 5-hour Codex limit
After demand for GPT-5.6 Sol surged, OpenAI's Codex lead said the 5-hour usage limit was temporarily removed for Plus, Business and Pro plans and usage was reset for everyone. Weekly limits still applied.
OpenAI+Codex adds banked rate-limit resets
Eligible Plus and Pro users can bank rate-limit resets, with one free reset at launch, and banked resets last 30 days. Usage-limit errors now also show when the limit resets, where available.
Anthropic·/usage stops showing percent of limit used
A user reported that in Claude Code v2.1.160 the /usage command no longer showed a progress bar or percentage of the session and weekly limits, only cost and category breakdowns. The report was closed as a duplicate.
Google+Google eases new Gemini limits after complaints
Google capped how much quota a single Gemini 3.1 Pro prompt can use, stopped charging failed requests, and made Flash-Lite prompts free. It said the gemini.google.com/usage page only gives a high-level overview and promised more detailed breakdowns.
Anthropic·/usage adds breakdown of what drives limit use
Claude Code v2.1.149 added a per-category breakdown to /usage showing what is driving limits usage: skills, subagents, plugins and per-MCP-server cost. The date is the npm release date of that version.
Google±Gemini app moves to compute-based 5-hour/weekly limits
Google replaced daily prompt limits with a 'compute-used' model that refreshes every five hours until a weekly limit is reached. The two AI Ultra tiers get 5x and 20x the AI Pro limit, and users can check usage at gemini.google.com/usage.
Anthropic+Temporary 50% boost to Claude Code weekly limits
Anthropic raised Claude Code weekly limits by 50% starting May 13, 2026 for Pro, Max, Team and seat-based Enterprise users. Five-hour limits and other Claude products were unchanged; the promotion was later extended several times.
Anthropic+Claude Code 5-hour limits doubled, peak cut removed
Anthropic doubled Claude Code's five-hour rate limits for Pro, Max, Team and seat-based Enterprise plans, effective the same day. It also removed the peak-hours limit reduction for Claude Code on Pro and Max.
OpenAI±New $100 Pro tier with 5x Plus Codex usage
OpenAI added a $100/month Pro plan with 5x the Codex usage of Plus (up to 10x through May 31), while the $200 Pro plan offers 20x. Plus usage was rebalanced to spread sessions across the week rather than allow long single-day sessions.
Anthropic−Claude 5-hour session limits drain faster at peak hours
An Anthropic engineer said on X that the 5-hour session limit runs down faster on weekdays 5am-11am PT, while weekly limits stay the same. He said about 7% of users would hit session limits they would not have hit before.
Google−Gemini CLI free tier limited to Flash models
The Gemini CLI team announced on March 18 that from March 25, Gemini Pro models are only available with a paid subscription and free users are limited to Flash. Traffic is also prioritized by license type, so some users may hit capacity limits at busy times.
Anthropic−Anthropic adds weekly limits on top of 5-hour limits
Announced July 28, 2025: two weekly limits, one overall and one for Opus 4, were added on top of the 5-hour limits starting August 28. Anthropic estimated Pro gets about 40-80 hours of Sonnet 4 a week in Claude Code and said fewer than 5% of subscribers would be affected.
OpenAI+GPT-5 Thinking cap for Plus raised to 3,000 a week
Sam Altman said the GPT-5 Thinking limit for ChatGPT Plus users went from 200 messages per week at launch to 3,000 per week, and that rate limits may change depending on usage.
Anthropic−Claude Code limits tightened without notice
From Monday July 14, heavy Claude Code users, many on the $200 Max plan, hit stricter usage limits that Anthropic had not announced. Users saw only a 'Claude usage limit reached' message with a reset time, and Anthropic gave no details.
