Can I run it?
Can I run Kwaipilot KAT Coder V2.5 Dev on AMD Ryzen AI Max+ 395?
Runs
Runs fully in unified memory on your AMD Ryzen AI Max+ 395 at Q8_0, 8K context, about 9.3–13 tok/s. Weights 34.4 GB plus 0.19 GB of KV cache — 35.2 GB of 48.0 GB usable. Up to 256K context still fits.

Assumptions
- Estimate from memory bandwidth, not a benchmark. Decode speed uses 55–75% of peak bandwidth.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- Q8_0 size is the real GGUF file size from Hugging Face.
- Unified memory uses 75% for the GPU by default, and always leaves about 5 GB for the OS.
- Speed is quoted at 8K context, not at the maximum context that still fits.
