01 / The short version

What happened

llama-modchip v2.4.0 enables CPU-only inference of large models without GPUs. The publisher claims DeepSeek-V4-Flash 284B runs on 64 GB RAM using 56.56 GiB disk space and 57.61 GiB peak VmRSS at 256K context, with prefill speeds of 44.36 tok/s and decode speeds of 9.06–14.7 tok/s. Nemotron-3.5-30B-A3B reportedly runs at 25.0–60.4 tok/s on 16-core Zen 5 hardware using 14.35 GiB RAM. The software uses Fractal-64 quantization and Stockfish-PVS speculative decoding. A pre-compiled Linux binary and Hugging Face GGUF models are available via GitHub Release v2.4.0. Performance claims are attributed to the publisher and have not been independently validated.

02 / Key takeaways

What you need to know

  1. 01

    DeepSeek-V4-Flash 284B reportedly fits in 64 GB RAM at 57.61 GiB VmRSS.

  2. 02

    Nemotron-3.5-30B-A3B reportedly achieves 25.0–60.4 tok/s on pure CPU.

  3. 03

    Custom GGUF tensor type 40 requires patched binaries and will fail in unpatched llama.cpp, Ollama, or LM Studio.

Keep in perspective

What to watch for

Performance figures are publisher-claimed; independent benchmarks are needed to verify speed and memory usage.
