Terminal Bench 4 Released: Removes 8 Tasks for Saturation and Refusals

cwolferesearch · x · 2026-08-30

Terminal Bench 4 has been released just a month after version 3, marking a shift to a continuous-style benchmark. No new tasks were added; instead, 8 tasks were removed based on feedback from TB3 to reduce noise. Removal reasons include task saturation (100% solve rate by latest models), high refusal rates, existing public solutions, and quality issues. The update focuses on fixing known issues and improving evaluation infrastructure.
