Claude Opus 5.5 becomes the default Claude model
Understand this story
Anthropic has made Claude Opus 5.5 the default model for Claude on the Pro, Max, Ultra, and Team plans, and recommends it as the everyday workhorse model for research, analysis, and document production. Anthropic says that on these plans, more expensive models consume usage limits faster; on the Pro plan and on standard seats of the Team and seat-based Enterprise plans, the limits do not include Fable 5.2 except under limited-time launch offers, and using Fable 5.2 draws on usage credits. On the Team and Enterprise plans, connectors must be enabled by an administrator before members can use them.

- Claude BlogFeaturedUsing Claude Opus 5.5 as your daily driver for knowledge work
Anthropic says Claude Opus 5.5 is now the default model on Pro, Max, Ultra, and Team plans and recommends it for daily knowledge work such as research, analysis, and producing memos, reports, spreadsheets, and decks, priced at $4/$20 per million input/output tokens. The post describes internal tests on research reports and a fictional merger analysis, plus guidance to start at Medium effort, drop "think hard" prompts, and attach charts rather than retyping them. It also walks through a demo project where Opus 5.5 tested four theories for slowing retail growth and proposed an alternative explanation involving new stores opening too close to existing ones.
