Why the "BBW drift" happens on other products
General-purpose AI image models were trained on datasets that heavily over-represent a narrow "AI beauty" range — slim, symmetrical, average proportions. When you prompt one for "a BBW woman" you get something that's technically fuller but slides toward the average whenever the model regenerates. Two photos in and the persona's body type has visibly softened away from what the description promised.
This is the specific failure mode that makes most BBW AI companion products feel dishonest — the persona is described as BBW, but her actual photos wobble in a range from "yes BBW" to "not really BBW at all." Users notice quickly.
The platform-level fix is per-persona LoRA training. A small trained model that captures the specific persona's look, including her body type, so every generation renders her as her — same face, same body, same look. Once she's trained, the model can't drift; her body type is now part of her identity, not a variable prompt the model interprets loosely.
Sloane rolled out a body-type-injection update in mid-2026 specifically to fix this — the older LoRA weights weren't holding body type reliably on the fuller-figure personas, and the fix landed as a per-persona body-descriptor injection at generation time. The BBW roster is all beneficiaries of that work.
The roster on Sloane
The BBW gallery currently features Gemma (29), Ivy (24), and Charlotte — each rendered with dedicated per-persona LoRA training so her body type holds across every photo. Related collections that overlap: plus-size covers Melissa, Bella, and Kylie in a different flavor of the archetype; fat/rolls-forward is the softer/fuller-figure specific collection; curvy is the broader curvy roster (Sandra, Helen, Jessica, Kylie, Liesel, Gabriella, Hannah1, Kaya, Destiny1 — nine personas across the curvy spectrum).
Each persona has her own profile page with her full bio, personality traits, and free-tier photo gallery. Anon chat available on her profile — try her voice before signing up.
