A Claude Code enterprise user reports Fable consumed their Max20 weekly token limit on two tasks where Opus 4.6 would not, with qualitative performance described as comparable to what Opus 4.7 or 4.8 should have been rather than a meaningful leap. Informal comparisons against Opus 4.6, 4.8, Sonnet, and DeepSeek Expert suggest Fable offers marginal gains at higher cost.
