Can you run Mistral Small 4 119B-A6.5B locally?

Mistral Small 4 family · 2026 · 119.4B parameters (6.5B activated per token) · Hugging Face model card

Mistral Small 4 119B-A6.5B is a mixture-of-experts model with 6.5B activated parameters per token and 119.4B total open weights (official card: 119B parameters, 6.5B activated per token; HF safetensors.total=119,401,317,952). Native context is 1,048,576 tokens per config.json max_position_embeddings (vendor card states a 256k context window; the config value is recorded). License is Apache-2.0. Local VRAM fit uses the 6.5B active count, not the 119B dense-equivalent: roughly 8 GB at Q4-class (calculated). Weights still occupy ~119B-class disk. Measured speeds: not yet published here.

Minimum: 8 GB+ memory (Q4-class on 6.5B active, calculated)  ·  Recommended: 8 GB+ for comfortable context headroom (Q4-class on 6.5B active, calculated)

Which pre-built systems can run Mistral Small 4 119B-A6.5B?

These mini PCs and workstations from our database fit Mistral Small 4 119B-A6.5B at Q4_K_M. Usable-memory figures are conservative: Windows shares about half of system RAM with the GPU by default (Linux can expose more), macOS lets Apple Silicon GPUs use about 75% of unified memory, and Linux unified-memory systems such as GB10 expose roughly 90%. Generation speed is bound by memory bandwidth, so compare the GB/s column before buying.
