Can I run Kwaipilot KAT Coder V2.5 Dev on GeForce RTX 3070?

Expert offload

Expert offload on your GeForce RTX 3070: Q3_K_L keeps shared weights on the GPU and about 10.0 GB of experts in system RAM. About 24–33 tok/s. Active-parameter speed is approximate.

Run commands

# Expert offload is approximate. llama.cpp can pin experts to CPU:
#   -ot "\\.ffn_.*_exps\\.=CPU"
llama-server -hf bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF:Q3_K_L -c 8192 -ngl 99

lms get bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF
# Then load quant Q3_K_L

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%.
• Q3_K_L size is the real GGUF file size from Hugging Face.
• 0.5 GB is reserved because this GPU also drives a display, then 5% of the rest is left free.
• Speed is quoted at 8K context, not at the maximum context that still fits.
• Mixture-of-experts split is approximate: shared layers on the GPU, expert tensors in system RAM. Speed reads more than the active-parameter slice, because shared layers stay on the bus.
