DeepSeek V4.1 Flash vs Kimi K3.1 Pro on a Three.js 3D engine lab
Same prompt in AgenC Core to build an interactive Three.js V8 engine lab: DeepSeek took 48 min, $0.86 and 67.2M tokens; Kimi took 31 min, $2.16 and 3.5M tokens, with a more polished UI while DeepSeek built a more detailed dyno cell.
DeepSeek V4.1 Flash vs Kimi K3.1 Pro tested both models with the same prompt at max effort in AgenC Core: build an interactive 3D V8 engine lab in Three.js. both delivered working simulations with RPM controls, slow motion, exploded views and part inspection. but the resource usage was VERY different > DeepSeek took 48 mins and cost $0.86 > Kimi took 31 mins and cost $2.16 DeepSeek used 67.2M total tokens, while Kimi used just 3.5M. Kimi had the more polished UI and a combustion sequence panel, while DeepSeek built a more detailed dyno cell. one thing to note: DeepSeek was still refining its result when it was stopped, while Kimi finished on its own. which one would you pick? 👀
