Five coding models build a Three.js KAFD flyover: DeepSeek V4.1 Flash ranks fourth
Five models were asked to build and render a 15-second Three.js flyover of Riyadh's KAFD from OpenStreetMap data; DeepSeek V4.1 Flash, run on 4 DGX Sparks, placed fourth behind Sonnet, MiMo and Haiku, ahead of Qwen.
I gave 5 AI coding models the same brief: build a 15-second cinematic flyover of KAFD, Riyadh’s financial district, from real OpenStreetMap data in Three.js, then render it to video. Claude Sonnet and Haiku ran in Claude Code desktop. DeepSeek v4.1 flash on 4 DGX sparks, Qwen 3.8 flash next on 2 dgx sparks and MiMo v2.6 Pro are open models that I ran in OpenCode. My ranking: Claude Sonnet MiMo (best open model, so it gets the big window) Claude Haiku DeepSeek Qwen Sonnet looks the most like the real district. MiMo is the closest open model.
