## Description (written by Gemini from the video)

**Summary**
In this video, creator World of AI reviews and tests Xiaomi’s open-weights model release, the MiMo-V2.6 series (including MiMo-V2.6-Pro and MiMo-V2.6-Flash). The presenter examines official benchmarks, pricing, and architecture details before putting the models through hands-on evaluation runs generating interactive front-end web pages, 3D browser games, algorithmic visualizers, and operating system clones.

**What is shown**
- [00:13–00:27] Xiaomi demo clips showing an interactive 3D open world, embodied robotic arm manipulation simulation, and a 3D RTS game interface.
- [00:28–00:45] Overview of the MiMo-V2.6 announcement tweet and blog post highlighting the Pro, Flash, and UltraSpeed variants.
- [01:18–01:46] Testing MiMo-V2.6 Pro on the presenter's custom "World of AI Bench" evaluation platform, highlighting an overall score of 83.3.
- [01:55–03:22] Review of official benchmark comparison tables across coding, agentic, visual coding, cyber, and the Artificial Analysis Intelligence Index.
- [03:23–04:04] Clip of a 3D open-world horse-riding game demo generated by MiMo-V2.6 Pro in Unity.
- [04:30–04:55] Breakdown of API token pricing and context window specifications from Xiaomi's open platform documentation.
- [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.
