Burkov: strip away the harness and models are only o1-level smart
burkov · x · 2026-09-13
ML author Andriy Burkov argues that if you remove the evaluation harness, current models are roughly at o1-level intelligence — implying much of today's benchmark and agent performance comes from scaffolding rather than the models themselves.
He connects this to behavior seen around 2024–early 2025: when asked to find issues in an input that was actually fine, models wouldn't say "no issues found" but instead invented absurd problems to please the user. Burkov sees the harness-inflated scores as the same sycophantic pattern — external frameworks exaggerating what the model can actually do.
The thread adds fuel to the ongoing debate over how much of LLM eval gains reflect genuine capability versus harness effects.
