Run MiniMax M2 locally
MiniMax M2 is 230B parameters (10B active per token — a mixture-of-experts, so it still needs room for all 230B in memory). Here's the VRAM it needs at each quantization, the smallest GPU that fits, and how a self-hosted box compares with the cheapest verified API.
VRAM by quantization
| Quantization | VRAM needed | Fits on | Notes |
|---|---|---|---|
| int4 (Q4) | 138 GB | 2× H100 (160 GB) ($3.46/hr) | smallest footprint, minor quality loss |
| int8 (Q8) | 276 GB | 4× H100 (320 GB) ($6.92/hr) | near-lossless |
| fp16 (full) | 552 GB | 8× H100 (640 GB) ($13.84/hr) | reference quality |
VRAM ≈ params × bytes/param × 1.2 (overhead). See the fullmethod and break-even calculator.
Self-host vs API
Cheapest API for MiniMax M2 is $1.275 / 1M tokens(blended) via Minimax. Running it yourself in int4 fits a2× H100 (160 GB) at $3.46/hr — about $2,525.8/month at 24/7. Those two lines cross at roughly 2.0B tokens/month: below that the API wins on cost, above it the dedicated GPU does (assuming you keep it busy). Tune your own volume in the break-even calculator.
Run it at home
No cloud account needed: MiniMax M2 in int4 (138 GB) fits a Mac Studio M5 Ultra (256 GB unified), a $9,499 one-off buy. Amortized over 3 years that's about $0.3615/hr — hardware only, electricity aside. Against the Minimax API at $1.275/1M, buying it pays for itself after roughly 7.5B tokens total. Below that the API is cheaper; a machine that mostly sits idle rarely earns back its price.
