Fable 5.1 day one: best model ever, but 30% quota gone in a day
momkeeeeeeee · reddit · 2026-09-02
A heavy user calls Fable 5.1 the best model he's ever used on day one: it cleaned up his memory store, connected three blood panels, and excelled in Claude Code — but burned 30% of his monthly usage in a day, partly because he keeps stopping it from spawning Opus 5 subagents that ruin projects. His thesis: if Opus 5.1 fixes personality, communication, dishonesty and overreach, the "Fable thinks, Opus does" stack wins over many users; otherwise Fable stays a 4-day ration. He sees Anthropic's rough patch ending only if Opus 5.1 lands well.
