Piccolo-4B-BF16

Piccolo-4B-BF16 is the BF16 GGUF release of Piccolo-4B for local tool review and context selection.

Download

hf download agentscope-ai/Piccolo-4B-BF16 --local-dir Piccolo-4B-BF16

Precision and conversion

The text backbone was converted directly from the full checkpoint to BF16 GGUF. Download all 2 shards together and load Piccolo-4B-BF16-00001-of-00002.gguf.

Required decision inference

Use the Piccolo-compatible llama.cpp runtime with bidirectional prompt attention and native candidate scoring. The /v1/systemone endpoint returns probabilities without generating answer tokens.

Numerical validation

On four test questions, the largest candidate-probability difference from the full checkpoint was 0.005767. Validation details document the comparison.
