• [04:56–05:36] Generation of an editorial SaaS landing page (“Meridian”) evaluated inside the benchmark interface.
• [05:37–06:23] Demo of a playable 3D Sonic the Hedgehog-style browser game generated using Three.js and HTML5, complete with loops, collectable rings, and physics.
• [06:24–07:11] Review of clean front-end UI designs generated by MiMo showcased in Xiaomi’s technical report.
• [07:12–08:31] An interactive product landing page generated for an “RTX 5090”, featuring a rotatable 3D GPU render and animated cooling chamber diagrams.
• [08:32–09:32] A 3D “Endless Donut” Formula racing simulation in Three.js featuring audio, tire smoke, telemetry overlays, and multiple camera angles.
• [09:33–10:17] An interactive 3D isometric room study with object tooltips and environmental sound toggles.
• [10:18–10:48] An animated, interactive SVG landscape painting (“The Golden Vale of Lysmora”).
• [10:49–11:43] An animated NYC skyline vector illustration featuring a live day/night cycle and moving traffic.
• [11:44–12:46] A fully interactive Windows 95 desktop simulation containing functional dialogs, a file explorer, terminal, and retro browser.
• [13:06–13:34] Complex utility tool generations including a pathfinding algorithm visualizer and a scientific graphing calculator.
• [13:35–14:34] A 3D island management simulation game (Tropico-style) with building placement and resource management mechanics.

Claims & numbers

• The presenter notes that MiMo-V2.6 includes two natively omnimodal models (Pro and Flash), an exploration of the RSI (Recursive Self-Improvement) path, and scaled reinforcement learning on verifiable complex tasks.
• The presenter states MiMo-V2.6-Pro scores 46.32 on the Artificial Analysis Intelligence Index, making it the highest-scoring open-weights model to date, beating Kimi K3 and Qwen3.8-Max.
• The presenter states that Pro performs on par with Claude Opus 5 and GPT-5.6 Sol across most agent benchmarks.
• The presenter cites Xiaomi’s claims that MiMo-V2.6-Pro costs 1/20th to 1/60th as much as leading frontier models at comparable intelligence.
• The presenter reports that API pricing remains unchanged from V2.5: Flash costs $0.0028 per million cached input tokens ($0.14 cache miss) and $0.28 per million output tokens; Pro costs $0.0036 per million cached input tokens ($0.435 cache miss) and $0.87 per million output tokens; Pro-UltraSpeed delivers up to 20x faster generation at $0.036 input (cache hit) / $4.35 (cache miss) and $8.70 output per million tokens.
• Both models feature a 1-million-token context window.

Notable quotes

• [01:29] “We found it to be the best open-weight model currently, and it is something that excels in multiple domains...”
• [02:07] “...costs just 1/20th to 1/60th as much as leading international models at comparable intelligence.”
• [05:41] “...MiMo version 2.6 Pro was able to build out a full 3D Sonic-style game from scratch.”

Assessment This is an independent YouTube review and capability showcase of Xiaomi’s newly released open-weights models. The presenter demonstrates live, functional interactive web apps, 3D simulations, and coding evaluations generated by the model alongside official charts and benchmarks from Xiaomi’s release announcement.
