Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.
It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
Claude Code just dropped Remote Control π Start a session on your laptop, continue from your phone while walking your dog. The future of coding isn't at a desk.
The 1000x engineer isn't the one who codes fastest. They're the one who can: Write specs at scale. Orchestrate 50 agents. Hold business context in their AI stack. The bottleneck moved - it's not writing code, it's architecting.
The best developers aren't writing more code - they're writing better instructions. Prompt engineering isn't a buzzword, it's the new debugging. If your AI keeps making the same mistake, you haven't written the rule yet.
