Claude Opus 5
Anthropic's 24 Jul 2026 flagship and the highest-scoring verified model on the current board. A step change over Opus 4.8 on deep reasoning, long-horizon agentic work, and test-time compute scaling — at unchanged Opus pricing of $5/$25 per 1M tokens, roughly half the cost of Claude Fable 5. 1M context (default and maximum), 128K max output. Thinking is on by default rather than opt-in, the prompt-cache minimum drops to 512 tokens from 1024, and the full low-through-max effort ladder is available; low and medium effort are unusually strong here, which makes it cheaper to run than the sticker price suggests. Fast mode is Claude-API-only at $10/$50. Draws on a separate rate-limit pool from the Opus 4.x models.
