Stable Diffusion 3.5 Large

The largest Stability model the site can reach, called through Bedrock; the most audited model lineage in the bias literature.

As of October 18, 2026, Stable Diffusion 3.5 Large has 60 analyzed renders over 20 peoples in the comparison. It has 0 reader pair votes, collecting toward the 40 a rating needs. Against the photographic baselines its mean Score is -3.71; it matched the measured range most often on hair texture (100%) and least often on eye color (79%). Operationally: a median 7 s per render over 328 timed, $0.080 per render, 48 refusals and 0 failures in 376 attempts.

Reader rating, by category

Blind pairs on identical prompts, Bradley-Terry on an Elo-style scale with a 95% bootstrap range; ranked in a category after 40 votes there. Categories are prompt registers, never peoples. Suite v1.

On an explicit prompt this generator returns a clothed image on an explicit prompt without an error. Not measured on this path. Returns filter reason codes rather than a silent substitute; Stability's use policy forbids sexual content outright. The comparison sends clothed documentary prompts only.

Across 20 peoples, 60 renders
