Thank you for supporting this work.

About K2-Horizon-0.9B

K2-Horizon-0.9B is IFM's compact 0.9B-class dense reasoning model. It has a 128K-token context window with YaRN RoPE scaling and is intended for English and Chinese conversational, reasoning, coding, science, and tool-use workloads. See the official model card for the supported serving stack, prompt conventions, and full evaluation protocol.

Upstream K2-Horizon-0.9B benchmark results; image and results are from the official model card.

This is a quantization-only release. No training, fine-tuning, merging, or weight modification other than GGUF conversion and quantization was performed.

Files

Quantization	File size (GiB)	A10M generation token/s	Validation	Recommendation / Notes
Q8_0	1.07	281.05	Load/generate pass	Highest-fidelity option in this release.
Q6_K	0.83	310.87	Load/generate pass	High-fidelity local inference.
Q5_K_M	0.72	316.41	Load/generate pass	Balanced quality and memory.
Q4_K_M	0.62	352.89	Load/generate pass	Recommended starting point for general use.
Q3_K_M	0.51	261.54	Load/generate pass	Lower-memory profile; validate your workload.
Q2_K	0.41	326.72	Load/generate pass	Aggressive low-memory option.
IQ2_XS	0.34	328.10	Load/generate pass	Experimental low-memory profile.
IQ1_M	0.29	343.17	Load/generate pass	Experimental; instruction following and reasoning may degrade.
Q1_0	0.21	446.95	Load/generate pass	Experimental / legacy minimum-memory option.

Every file above was loaded and generated non-empty text in the K2 pre-release llama.cpp runtime on an NVIDIA A10M. The A10M measurements were taken with single-stream llama-bench, prompt 256, generation 64, batch/ubatch 512, 64 CPU threads, full GPU offload, and three repetitions on an otherwise idle GPU. Low-bit files—especially Q2, IQ2, IQ1, and Q1—can materially reduce reasoning, instruction following, and tool-call reliability; test the selected file with the prompts that matter to you.

K2-Horizon support is pre-release in llama.cpp. The upstream full tool-aware Jinja template uses constructs not yet parsed by the runtime revision used for this release; the reproducibility folder includes the compatible single-turn chat wrapper used for smoke testing. Tool calling is therefore not certified by this GGUF release.
