grug-27b-nvfp4

grug brain in NVIDIA four-bit float rock. Blackwell GPU eat this format raw = big speed, small memory, quality mostly keep.

• source: grug-27b (v2.1)
• scheme: NVFP4 (W4A4) via llm-compressor one-shot
• calibration: 512 samples of grug's own training distribution (agent sessions + grug reasoning) so scales match real usage
• kept high precision: lm_head, vision tower, router gates
