MiniMax M2.5 — Hardware Requirements & GPU Compatibility
Chat
MiniMax M2.5 is a large-scale mixture-of-experts model from MiniMax, a well-funded Chinese AI company. With roughly 228 billion total parameters and a MoE architecture that activates only a fraction per token, it aims to deliver performance competitive with much larger dense models while keeping inference costs manageable. Running it locally requires substantial hardware due to its large parameter footprint, but quantized versions can make it accessible to users with multi-GPU setups looking for a powerful multilingual model with strong Chinese and English capabilities.

Frequently Asked Questions
- How much VRAM does MiniMax M2.5 need?
MiniMax M2.5 requires 137.8 GB of VRAM at Q4_K_M, or 229.3 GB at Q8_0. Full 197K context adds up to 24.7 GB (162.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 228.7B × 4.8 bits ÷ 8 = 137.2 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 25.3 GB (at full 197K context)
