Available quantizations

File	Quant	Size	Notes
`qwen3.5-4b-sft-fable5.q4_k_m.gguf`	Q4_K_M	2.59 GiB	Smallest here; the common choice for local inference on limited VRAM.
`qwen3.5-4b-sft-fable5.q5_k_m.gguf`	Q5_K_M	2.94 GiB	Balanced. The usual default when Q4_K_M feels lossy.
`qwen3.5-4b-sft-fable5.q8_0.gguf`	Q8_0	4.29 GiB	Largest, closest to the merged weights. Use when disk is not the constraint.

Sizes above are the actual file sizes in this repository, not estimates.

Limitations

Quantization is lossy: outputs will not match the source model exactly, and the effect grows as the quant level drops.
Primarily English training data.
Not safety-tuned. Use appropriate guardrails.
Research and prototyping, not production without further evaluation.
