# VibeThinker-3B achieves 80.2 on LCBv6 > Source: > Published: 2026-06-16 21:08:26+00:00 ⭐ VibeThinker-3B is released — a dense 3B model for frontier-level verifiable reasoning. 🚀 Reasoning: 94.3 on AIME’26, 76.4 on IMO-AnsBench, and 80.2 Pass@1 on LCB v6; with CLR, AIME‘26 improves to 97.1 and IMO-AnsBench to 80.6. 💻 OOD Coding: On recent unseen LeetCode weekly B passes 123/128 (96.1%) first-attempt Python submissions. ⚡ Efficiency: Only 3B parameters, yet reaching the performance range of much larger top-tier reasoning models. 🧠 Perspective: Small models are not just cheaper substitutes. In parameter-dense domains with clear verification signals, SLMs offer a path to frontier-level reasoning that complements traditional Scaling Law. Model :
