ThinkingMachines' Distilled Small Model Beats Large Model in Coding and Reasoning

量子位 · wechat · 2026-07-31

ThinkingMachines released the Inkling-Small model (276B total parameters, 12B active). Surprisingly, this distilled model outperforms its larger teacher model on certain metrics: scoring 31.6% on HLE (vs. 29.7% for the large model) and breaking 80% on SWEBench Verified (vs. 77.6%).

This isn't just cherry-picking benchmarks; at equivalent compute costs, the small model's test-time compute curve consistently stays above the large model's. The official recipe for this success involves leveraging the time gap to adjust pre-training data ratios, applying online policy distillation using the large model as a teacher, and finishing with two extra weeks of RL specifically for agentic coding.

However, the announcement also notes the small model's limits: on hard knowledge and factual tasks that rely on parameter scale (like SimpleQA Verified), the large model still holds a decisive advantage.
