Introducing Claude Opus 5.5

Claude Opus 5.5 has been introduced, performing at the level of Claude Fable 5.1, Anthropic's most intelligent model. It offers clearer writing, prioritizes important information, and is faster and more efficient than Opus 5. This makes it suitable for larger tasks and extended use. Opus 5.5 is now available everywhere, and usage limits on Pro, Max, and Team plans have been increased to celebrate its launch.
