Released in mid-April 2026 and superseded by Opus 4.8 just six weeks later, Opus 4.7 mainly matters now for what it introduced: the new tokenizer that all subsequent Anthropic frontier models (Opus 4.8, Fable 5, Mythos 5) use, and always-on adaptive thinking in place of the extended-thinking toggle.\n\nThe tokenizer is the trap. The same text produces roughly 30% more tokens than on Opus 4.6 and earlier, which raised effective costs by up to 35% for some workloads despite the unchanged $5/$25 rate card. Teams that skipped 4.7 still hit this when migrating from 4.6 to 4.8. Its reliable knowledge cutoff is January 2026 -- notably fresher than Opus 4.6's May 2025.\n\n**When to pick something else:** Almost always. Opus 4.8 is a config-only upgrade -- same API surface, tokenizer, context window, and pricing -- with better capability and cheaper Fast Mode. There is no reason to start a new project on 4.7.","content_length":2815,"generated_at":"2026-06-22"}
