Astra vs Fable: one follows your typo literally, the other quietly fixes it

bclavie · x · 2026-09-05

Developer bclavie shares a hands-on behavioral comparison of Astra and Fable: Astra is more "task-intelligent" while Fable feels more human in intuition.

In one example, after a typo, he requested pass@40 (4) from Astra, which dutifully acknowledged and started. Fable instead replied: "I am going to interpret pass@40 as a typo and measure pass@4." A neat illustration of strict instruction-following vs. commonsense correction tradeoffs.
