The reasoning engine behind Tanka just got a major upgrade. @miromind_ai just released MiroThinker-1.7 and MiroThinker-H1 — and the benchmark numbers speak for themselves: BrowseComp 88.2, GAIA top-tier, leading on financial and scientific research tasks. At Tanka, we've been building on MiroMind's reasoning infrastructure from the start. Better step-level accuracy and deeper verification directly translates to better results for our users — every search, every insight, every answer. This is what "AI that actually works" looks like under the hood. 🧠
