GA

Legacy: its model page reads 'Legacy. Released July 24, 2026' and 'Although Claude Opus 5 is still available, you should consider migrating to Claude Opus 5.5 for improved performance'; the deprecations table still reads Active with a tentative retirement not sooner than July 24, 2027, so status stays ga (legacy is not a lifecycle stage in that table). $5 in / $25 out per MTok; 5m cache $6.25, 1h cache $10, cache hits $0.50/MTok; Batch $2.50/$12.50; Fast mode $10 in / $50 out. Adaptive thinking; effort defaults to high. 1M context, 128K max output (300K via the Batch API beta header). Reliable knowledge cutoff May 2026. Tool-use system prompt overhead 286 tokens (auto/none) or 406 (any/tool). Added 2026-10-02, ten weeks after release: the delay is ours, and until today this catalog carried Opus 4.8 as the newest Opus.
