On 1 Oct 2026 @claudeai said that for two weeks, starting a design, deck, or doc in the Claude app makes the work that follows in that conversation use 50% less of usage limits. The post points people at Claude Sonnet 5.5.

Hit the 5-hour wall and Claude Code tries to land the plane

The cutoff still happens. It just borrows next week's meter to finish the sentence.

On 25 Sep 2026 @ClaudeDevs said Claude Code will try to find a graceful stopping point when a 5-hour limit hits mid-task, instead of cutting off mid-edit. The wrap-up uses a small, fixed allowance pulled from the weekly limit.

Opus 5.5: 20% more session, 25% further, one reset in the drawer

On 22 Sep 2026 Anthropic launched Claude Opus 5.5 and raised five-hour usage limits on Pro, Max, and Team. @ClaudeDevs said session limits increase 20% that day, Opus 5.5 goes 25% further inside limits because it is priced lower than Opus 5, and paid plans get a reset they can apply any time until 22 Oct.

Capacity theater, act three: the encore is a credit and a percentage.

Fable 5 rolled into Max and Team Premium at 50 percent of limits from July 20. Pro and Team Standard get usage credits and a one-time $100 credit. Staged access blamed on unpredictable demand. Claude Code weekly limits stay 50 percent higher through August 19.
