Claude Opus 4.7 and later Opus models, Claude Fable 5, Claude Mythos 5, Claude Mythos Preview, and Claude Sonnet 5 use a newer tokenizer that contributes to their improved performance on a wide range of tasks. This tokenizer produces approximately 30% more tokens for the same text. The exact increase depends on the content and workload shape. Claude Sonnet 4.6 and earlier models use the previous tokenizer.
Fast mode , in research preview, provides significantly faster output for Claude Opus 4.8 and Claude Opus 4.7 at premium pricing. Fast mode pricing applies across the full context window, including requests over 200k input tokens. Fast mode is not available on Claude Platform on AWS.
Fast mode for Claude Opus 4.7 is deprecated and will be removed on July 24, 2026. As of June 29, 2026, fast mode is not available on Claude Opus 4.6: requests to claude-opus-4-6 with speed: "fast" run at standard speed and are billed at standard rates. See Fast mode .

Claude Fable 5, Claude Mythos 5 , Claude Mythos Preview , Claude Opus 4.8, Opus 4.7, Opus 4.6, Sonnet 5, and Sonnet 4.6 include the full 1M token context window at standard pricing.
