Can you run MiMo V2.6 Pro RL locally?
MiMo V2.6 family · 2026 · 1.02T parameters (42B activated per token) · Hugging Face model card
MiMo V2.6 Pro RL is a mixture-of-experts reasoning model with 42B activated parameters per token and ~1.02T total open weights (official card: Sparse MoE, 1.02T total / 42B activated; HF safetensors.total=1,024,216,603,392). Native context is 1,048,576 tokens (card: 1M). License is MIT. Local VRAM fit uses the 42B active count, not the 1.02T dense-equivalent: roughly 32 GB at Q4-class (calculated). Weights still occupy ~1T-class disk. Measured speeds: not yet published here.
Minimum: 32 GB+ memory (Q4-class on 42B active, calculated) · Recommended: 32 GB+ for comfortable context headroom (Q4-class on 42B active, calculated)
How much VRAM does MiMo V2.6 Pro RL need at each quantization?
MiMo V2.6 Pro RL needs 677.7 GB of VRAM at Q4_K_M. The table below lists weights-only size and total VRAM including overhead for each common quantization level with 4k and 32k token contexts.
| Quantization | Bits / weight | Weights only | Total + KV @4k ctx | Total + KV @32k ctx |
|---|---|---|---|---|
| Q4_K_M | 4.8 | 614.5 GB | 677.7 GB | 690.1 GB |
| Q5_K_M | 5.7 | 729.8 GB | 804.5 GB | 816.8 GB |
