summary: "The latest flagship AI assistant delivers performance parity with Fable 5.1 for most general tasks and operates 30% faster than the previous Opus 5 iteration. Anthropic priced the model at $4 per million input tokens and $20 per million output tokens, a 20% reduction from Opus 5, while cache reads dropped 60% to $0.20 per million tokens. The system is now the default for Pro, Max, and Team subscription plans, which include a 20% increase in 5 hour usage limits. The launch introduces a safety mechanism where the model falls back to less capable versions for specific frontier LLM development tasks, including kernel coding. In enterprise trials by Box, the model used 63% fewer tokens and reduced verbosity by 42% for knowledge work tasks. General availability has extended to third party integrations such as GitHub Copilot, Cursor, and Devin."
