Reddit user /u/jesdga95 reported running the same one-shot prompt for an interactive V8 engine with two local models. DeepSeek V4.1 Flash 1017, using UD IQ1_M quantization and a single agent, generated about 250,000 tokens at roughly 94 tokens per second over about 60 minutes, used a 346,000-token context without compaction, and produced an engine the author said ran on the first attempt with working buttons. Qwen 3.8 FN, using NVFP4 quantization with one main agent and five subagents, ran at about 350 tokens per second in aggregate and took around 70 minutes. Two subagents did not complete their assigned work, while the author said the result included more parts and a better cutaway but also floating components and a less attractive appearance.
