RFD 1043 details: the model, the interface, the open quality question

The model

Property	Value
Parameters	27.0 B, published
bf16	54.0 GB, never built
Q4_K_M	14.85 GB, the ship format
License	Apache 2.0

The count covers the edit backbone and the vision language encoder that reads the instruction. The encoder is not optional, because the instruction is text and the edit is spatial.

The interface

Input	Type	Default
image	Path	none
instruction	str	none
strength	float	0.8
steps	int	20
seed	int	-1

instruction is a sentence, and not a tag list. “Make the jacket red” works. “jacket, red” does not, because the encoder reads language.

The quality question stays open

No measurement compares Q4_K_M against bf16 for this model. The saving is certain, and the quality cost is not.

Measure before the catalog depends on it. Run 20 edits in each format, and compare them by eye. RFD 1027 permits both formats, thus a bf16 build stays legal if the measurement demands it.
