## How the score was worked out Each result implies a score on its own, after adjusting for how hard that test is and who ran it. The model's score is their weighted average, with a small pull toward the middle for thinly tested models. Each test's weight is its *counts* column above; here it is added up by who ran the tests.

Install llama.cpp. Homebrew and winget installs name the commands llama-cli and llama-server instead. [Other ways to install](https://github.com/ggml-org/llama.cpp/blob/master/docs/install.md) ```sh # macOS / Linux curl -LsSf https://llama.app/install.sh | sh # Windows irm https://llama.app/install.ps1 | iex ``` 2. Run Kimi K3 (ud-q4_k_xl, needs ~1680.5 GB, from [huggingface.co/unsloth](https://huggingface.co/unsloth/Kimi-K3-GGUF/tree/main)) ```sh llama cli -hf unsloth/Kimi-K3-GGUF:UD-Q4_K_XL ``` 3. Or start a local server and open the address it prints (http://localhost:9931) ```sh llama serve -hf unsloth/Kimi-K3-GGUF:UD-Q4_K_XL ``` Other versions: ud-q2_k_xl (~840.5 GB) `llama cli -hf unsloth/Kimi-K3-GGUF:UD-Q2_K_XL` ### LM Studio 1. Install LM Studio. Open the app once before using the lms command. [Download it (macOS / Windows / Linux)](https://lmstudio.ai/download) 2. Run Kimi K3 (ud-q4_k_xl, needs ~1680.5 GB, from [huggingface.co/unsloth](https://huggingface.co/unsloth/Kimi-K3-GGUF/tree/main)) ```sh lms get https://huggingface.co/unsloth/Kimi-K3-GGUF@UD-Q4_K_XL -y ``` 3. Then run lms ls to see its name, and lms chat followed by that name Other versions: ud-q2_k_xl (~840.5 GB) `lms get https://huggingface.co/unsloth/Kimi-K3-GGUF@UD-Q2_K_XL -y` Model repository and documentation: [huggingface.co/moonshotai](https://huggingface.co/moonshotai/Kimi-K3) [interactive version](https://whatmodel.sh/model/kimi-k3) · [JSON](https://whatmodel.sh/api?format=json&all=1)
