> [!IMPORTANT]
> **Compatibility:** These GGUF files require a `llama.cpp` build with K2 Horizon architecture support. Until upstream support lands, use the [MBZUAI-IFM fork](https://github.com/MBZUAI-IFM/llama.cpp/tree/model/K2Horizon).

# K2-Horizon-3.7B GGUF

GGUF quantizations of [IFM/K2-Horizon-3.7B](https://huggingface.co/IFM/K2-Horizon-3.7B), a 3.7B dense decoder-only model for reasoning, coding, long-context work, and tool use. The source checkpoint supports a native context length of **524,288 tokens (512K)**.

## Benchmarks

![IFM/K2-Horizon-3.7B benchmark results](assets/k2-horizon-3.7b-benchmarks.png)

*Benchmark results reported by IFM for the original IFM/K2-Horizon-3.7B checkpoint.*

## GGUF files

| Quantization | File | Size |
| --- | --- | ---: |
| Q4_0 | [K2-Horizon-3.7B-Q4_0.gguf](K2-Horizon-3.7B-Q4_0.gguf) | 3.02 GB |
| Q4_K_M | [K2-Horizon-3.7B-Q4_K_M.gguf](K2-Horizon-3.7B-Q4_K_M.gguf) | 3.16 GB |
| Q5_K_M | [K2-Horizon-3.7B-Q5_K_M.gguf](K2-Horizon-3.7B-Q5_K_M.gguf) | 3.64 GB |
| Q6_K | [K2-Horizon-3.7B-Q6_K.gguf](K2-Horizon-3.7B-Q6_K.gguf) | 4.16 GB |
| Q8_0 | [K2-Horizon-3.7B-Q8_0.gguf](K2-Horizon-3.7B-Q8_0.gguf) | 5.39 GB |

## Chat template

Each GGUF embeds the llama.cpp-compatible chat template. [`chat_template.jinja`](chat_template.jinja) is a matching external copy for tools that require one. The original source template is retained as [`chat_template.upstream.jinja`](chat_template.upstream.jinja) for runtimes with full Jinja support.

`xml` is the default tool-call format. Use `--chat-template-kwargs` to select `json` or `xml_typed` when required.

## Usage

Use the [IFM K2 Horizon llama.cpp fork](https://github.com/MBZUAI-IFM/llama.cpp/tree/model/K2Horizon).

```bash
llama-cli \
  -m K2-Horizon-3.7B-Q4_K_M.gguf \
  -c 8192 -n 512 --jinja \
  -p "Explain why reproducible builds matter."
```
