K2-Horizon-3.7B GGUF

GGUF quantizations of 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).

GGUF files

| Quantization | File | Size |

| --- | --- | ---: |

| Q4_0 | K2-Horizon-3.7B-Q4_0.gguf | 3.02 GB |

| Q4_K_M | K2-Horizon-3.7B-Q4_K_M.gguf | 3.16 GB |

| Q5_K_M | K2-Horizon-3.7B-Q5_K_M.gguf | 3.64 GB |

| Q8_0 | K2-Horizon-3.7B-Q8_0.gguf | 5.39 GB |

Chat template

Each GGUF embeds the llama.cpp-compatible chat template. chat_template.jinja is a matching external copy for tools that require one. The original source template is retained as 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.

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