K2-Horizon-7B — GGUF Quantizations

GGUF quantizations of IFM/K2-Horizon-7B,

a dense 7B-parameter causal decoder (K2HorizonForCausalLM, model_type: k2_horizon).

Quantized by NANI-Nithin using a custom pipeline built on the

MBZUAI-IFM llama.cpp fork (branch model/K2Horizon).

---

Model Details

| Property | Value |

|---|---|

| Base model | IFM/K2-Horizon-7B |

| Architecture | K2HorizonForCausalLM (k2_horizon) |

| Parameters | ~7B (dense decoder, no MoE) |

| Original dtype | BF16 |

| BF16 GGUF size | ~18.01 GB |

| Source GGUF | IFM/K2-Horizon-7B-GGUF |

| llama.cpp fork | MBZUAI-IFM/llama.cpp @ model/K2Horizon |

> Note: These GGUFs carry the k2-horizon architecture token and require

> the MBZUAI-IFM fork (or upstream llama.cpp once support is merged) to run.

> Vanilla upstream llama.cpp (as of September 2026) does not support

> K2HorizonForCausalLM.

Quantization Method

• Source: IFM's official BF16 GGUF (K2-Horizon-7B-BF16.gguf).
• imatrix: Computed from Salesforce/wikitext

(wikitext-2-raw-v1, 500 rows) with 12 GPU layers offloaded on an RTX 4060 Laptop (8 GB VRAM)

due to the 18 GB model size. Applied to all K-quants below Q6 and all IQ quants.

• Fork: MBZUAI-IFM/llama.cpp, branch model/K2Horizon.

---

Usage

> Requires the MBZUAI-IFM llama.cpp fork (model/K2Horizon branch).

git clone -b model/K2Horizon https://github.com/MBZUAI-IFM/llama.cpp
cd llama.cpp && cmake -B build -DGGML_CUDA=ON && cmake --build build --config Release

./build/bin/llama-cli \
  -m K2-Horizon-7B-Q4_K_M.gguf \
  -p "Hello, I am" \
  -n 128 \
  -ngl 35
