Qwen 3.8 27b nvfp4 vs Grok 4.6 Someone tell me how this local model that is 100x smaller and 10x slower made a better animation?! Elon Musk help us solve this, both with their highest thinking mode (xhigh vs max)

Two models. One DGX Spark One identical voxel Eiffel Tower prompt. Qwen3.8-27B xhigh: 83K tokens, 41m29s, 33.4 tok/s Ornith 1.5 35B-A3B: 47K tokens, 10m35s, 74.0 tok/s Thinking on, no token ceiling, matched camera. Ornith finished much faster; Qwen spent far more tokens.

This is the worst model I have ever tested, even 9b models outperform it. What even is this pagoda? Same prompt I always use. - Total time: 9 min 21 s (560.9s) - Tokens: 6,891 completion (710 reasoning + ~6,181 answer) | 84 prompt - Speed: ~12.3 tok/s end-to-end - First token: 0.15s - Output: 22,094 chars answer / 17.2KB HTML, natural stop (finish_reason=stop, no cap hit)

Same quality class as full precision. Half the size of FP8. ~4× smaller than BF16.

Deepseek-v4.1 local vs Opus 5 chess: 2nd match Thinking on Reasoning low DeepSeek wins with checkmate in 22. So far thinking off Opus won Reasoning low Deepseek won Tiebreaker with thinking high underway. I’ll make a tournament style match off with more models. Best out of 3

Qwen3.8-Flash-Next (176B, NVFP4, 2× DGX Spark): 40,265 thinking tokens, 21,091 answer. Qwen3.8-27B on the same prompt: 42,988 thinking, 6,040 answer. Same question, same deliberation, 3.5× the output. 55 min vs 37 min. The 176B shipped a genuine leapfrog wave equation on a 512² lattice with reflections and interference. The 27B shipped a solid ripple tank. Both run 60fps in a single HTML file Generated on DGX Sparks on my desk.

16 people chatting with Qwen3.6-35B at once ONE DGX Spark. This is a real capture, not a mockup: every token you see replays at its actual measured arrival time. Peaks ~440 tok/s total. A single user gets 105 tok/s. NVFP4 + MTP-3 on vLLM.
