# 🚀 CPU optimized quantizations of [DeepSeek-V2-Chat-0628](https://huggingface.co/deepseek-ai/DeepSeek-V2-Chat-0628) 🖥️

### Currently ranked #7 globally on LMSYS Arena Hard! 🏆


>### 🚄 Just download this IQ4XM 132Gb version, it's the one I use myself in prod:
>🐧 On Linux `sudo apt install -y aria2`
>
>🍎 On Mac `brew install aria2`
>
>These links will download 9x faster, feel free to paste them all in or one at a time

>[!TIP]
>//then to have a commandline conversation interface all you need is:
```bash
git clone https://github.com/ggerganov/llama.cpp && cd llama.cpp && make -j
./llama-cli -m ~/r/deepseek_0628_cpu_optimized_iq4xm-00001-of-00004.gguf -t 62 --temp 0.4 -co -cnv -i -c 3000 -p "Adopt the persona of a full-stack developer at NASA JPL."
```
### 🧠 This IQ4XM version uses GGML TYPE IQ_4_XS 4bit in combination with q8_0 bit for blazing fast performance with minimal loss, leveraging int8 optimizations on most newer server CPUs.
### 🛠️ While it required some custom code wizardry, it's fully compatible with standard llama.cpp from GitHub or just search for nisten in lmstudio.

>[!TIP]
>
>📁 No need for file concatenation - just point llama-cli at the first file and watch the magic happen!
>
>💻 Ready to delve in baby? Here's your command-line spell for interactive mode (prompt.txt is optional, but recommended for maximum sorcery):
>```bash
