Claude Opus 5.5: the top tier got 40% cheaper and the subscriber limits went up
Anthropic introduced Claude Opus 5.5 on 22 September as the first model of the 5.5 family, priced at $4 per million input and $20 per million output — 40% below Opus 5 — and claims output arrives more than 30% faster. Alongside the model, the five-hour usage limits on Pro, Max, Team and seat-based Enterprise plans were increased.
For anyone on a subscription rather than the API, the limit change is the story. Price cuts on a model you do not buy per token are irrelevant; the wall you actually hit is the rolling usage window, and it moved in your favour. This is also the clearest example this month of why our profiles separate "what the API costs" from "what your plan lets you do".
