Notes
Claude Fable 5 released June 9, 2026 — Anthropic's first public Mythos-class model, positioned above Opus. Most expensive model on Anthropic's price list: $10/$50 per 1M tokens (2x Opus 4.8). Batch API halves both to $5/$25. Cache hits drop to $1/M. US-only inference at 1.1x. Available to Pro, Max, Team, and Enterprise users. Was suspended June 13 for 18 days under US export-control order, returned July 1. [2026-07-13] Context Window 200,000 → 1,000,000 and Max Output 64,000 → 128,000 per platform.claude.com docs + OpenRouter (Fable 5: 1M context, up to 128K output per request). Prices unchanged ($10/$50, cache read $1). [2026-07-20] Backfilled Cache Write 5m = $12.50, Cache Write 1h = $20.00 (explicit per pricing aggregators, consistent with Anthropic's standard 1.25×/2× write multipliers) and Batch Discount % = 50 (already documented in these notes). Prices unchanged ($10/$50, cache read $1). Data completion, not a market change — no snapshot written.
