Model Details

Property	Value
Quantization	Q4_K_M
File	brick-complexity-extractor-Q4_K_M.gguf
Size	494 MB
Bits per weight	5.5
Original model	regolo/brick-complexity-extractor
Base model	Qwen/Qwen3.5-0.8B
Output classes	3 (easy, medium, hard)
License	CC BY-NC 4.0

4-bit k-quant mixed precision. Best quality/size ratio. Ideal for edge and resource-constrained deployments.

This is a full merged model (base Qwen3.5-0.8B + LoRA adapter merged and quantized), so no separate adapter loading is needed.

All Available Quantizations

Model	Quant	Size	BPW
BF16-GGUF	BF16	1.5 GB	16.0
Q8_0-GGUF	Q8_0	775 MB	8.0
Q4_K_M-GGUF	Q4_K_M	494 MB	5.5

Note on GGUF Inference

The GGUF model uses generative text output (generates "easy", "medium", or "hard") rather than logit-based classification used by the original LoRA adapter. For production deployments requiring maximum accuracy, consider using the original LoRA adapter with the PEFT library.
