Kimi Dev 72B GGUF

🚀 ik_llama.cpp imatrix Quantizations of Kimi - Dev - 72B

This project offers quantized versions of the Kimi - Dev - 72B model. It focuses on providing high - performance quantizations that require a specific fork of ik_llama.cpp to function properly.

✨ Features

Quantization Requirements

This quant collection REQUIRES the ik_llama.cpp fork to support advanced non - linear SotA quants and Multi - Head Latent Attention (MLA). Do not download these big files and expect them to run on mainline vanilla llama.cpp, ollama, LM Studio, KoboldCpp, etc! Though might work in Nexesenex's croco.cpp kobold fork (untested).

📦 Installation

Quickstart

# Clone
git clone git@github.com:ikawrakow/ik_llama.cpp.git
cd ik_llama.cpp

# Build (might try adding -DGGML_CUDA_IQK_FORCE_BF16=1 for 3090s and older)
cmake -B build -DGGML_CUDA=ON -DGGML_CUDA_F16=ON -DGGML_SCHED_MAX_COPIES=1
cmake --build build --config Release -j $(nproc)

# Run (set threads to number of CPU physical cores, mmap is fine for faster startup, adjust ctx/ngl as needed)

Quality

I tested perplexity for a bunch of experimental quants, decided this one was a decent trade - off between quality and speed.

FAQ

1. Why is it smol?

• I ran out of names making a bunch of similar sized quants for the Perplexity graph above lol.

2. Will you make larger GGUFs?

• Naw, you can get good mainline llama.cpp GGUFs from others already like bartowski and bullerwins.

3. Where can I get those hot new EXL3 quants?

• Check out ArtusDev's collection

4. What about the new iqK_kt QTIP Trellis style quants?

• I may release something eventually, but they are still pretty fresh gonna wait a minute to see if any breaking changes happen before releasing.
• Also the column dimension of the ffn_down tensor is not divisible by 256 so had to use iq4_nl unless something changes.
