Can I Run MiMo-V2.5-Pro 1T on AMD Ryzen AI Max+ 395?
Written by Jakub Rusinowski · Last updated September 6, 2026
No. MiMo-V2.5-Pro 1T needs 610.3 GB at 8K context (603.8 GB weights + 6.5 GB KV cache/overhead) at Q4_K_M and the AMD Ryzen AI Max+ 395 has only 128 GB. No quantization we publish closes a gap that size.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 128 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the AMD Ryzen AI Max+ 395: 8K 610.3 GB ✗ · 32K 627.6 GB ✗ · 128K 696.9 GB ✗. Past 8K it no longer fits 128 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
