Claude Fable 5.1 maintains stable list pricing at $50 per million output tokens since its September 1, 2026 release, matching the earlier Fable 5 rate and positioning it as Anthropic’s premium tier for long-horizon agentic, coding, and reasoning workloads. Improved prompt caching at $0.25 per million reads delivers meaningful effective-cost reductions for cache-heavy usage, yet base output rates have not moved despite competitive models like Claude Opus 5.5 at $20 output. Traders are monitoring any year-end competitive responses, new frontier releases, or batch/caching policy tweaks that could alter the $50 level before December 31, 2026.
