MiroMind Releases MiroThinker-H1: Dual-Layer Inference-Time Verification Beats GPT-5.4 and Claude Opus 4.6 on BrowseComp

PR Newswire·medium signal

MiroMind released MiroThinker-1.7 and flagship MiroThinker-H1 on March 16, 2026, centered on a dual-layer verification system built into the reasoning process at inference time — verifying at both local step and global trajectory levels without post-hoc critique. MiroThinker-H1 scores 88.2 on BrowseComp, surpassing Gemini-3.1-Pro (85.9), Claude-4.6-Opus (84.0), and GPT-5.4 (82.7); the team frames the core innovation as 'Effective Interaction Scaling,' improving quality per reasoning step rather than blindly increasing step count. Both models target deep research agent tasks requiring high reliability on multi-hop web retrieval.
