The Harness Buys You One Model Generation

Manazir Ali bet that a swappable weak model wrapped in a strong harness, deterministic retrieval, curated tools, verification loops on a Laptop, could deliver frontier behavior. The published evidence graded the bet for him: the harness closes knowledge, format, and verifiable tasks, worth roughly one model generation, then hits a model-bound wall on multi-turn coherence and long-horizon autonomy.…
