Why do you people always specify the size of the breasts? That ruins the accuracy. The model works best by inferring the size from how they look when clothed.

Even without mentioning size grok seems to add a few cup sizes

Grok i2i has never been top tier the current iteration is the best in terms of quality and realism

Nah like until couple of days ago I got realistic looking images, now everything comes out very smoothed out that looks AI as fuck, no matter the prompting like:

• Skin texture boosters: detailed skin texture, visible pores, subtle skin imperfections, natural skin details, fine skin texture, realistic pores and freckles, slight blemishes, peach fuzz, subsurface scattering, natural skin variations, matte skin, textured skin, lifelike skin
• Lighting & photo realism: natural lighting, soft diffused lighting, realistic shadows and highlights, candid photography style, film grain, 35mm film, dslr photo, fujifilm colors, kodak portra 400, raw photo, authentic photo, slight grain, natural imperfections
• Overall authenticity: photorealistic, hyperrealistic but authentic, true-to-life, everyday realism, no airbrushing, imperfect beauty, natural pose and expression
  
  Still turns out to be AI, using old prompts like its day and night of images i got a week ago and now....

Hmm. Maybe try describing bra sizes. Like A cup, B cup, C cup? Gonna try it out.

I noticed Grok likes things simple. It draws mostly from reference imagine given. The lesser the word salad, the better it works.

I had the same issue and had Grok try to make a list of different sizes. This has worked pretty well for me but even with the very descriptive “very small” size it can still take a few tries.

Desired size	Strongest prompt phrases (combine 2–4 of them) + negation boosters	Notes / success rate
Very small / A–AA	small breasts, tiny breasts, subtle chest, flat-chested, barely there, modest bust, small perky breasts, micromastia, plus negation boosters like: no large breasts, no medium breasts, no prominent bust, no voluptuous chest, no cleavage, no heavy breasts, no exaggerated proportions, realistic small chest without implants, flat chest realistic proportions, petite frame no bust emphasis, subtle barely noticeable breasts, avoid large or average bust	Often needs heavy negation of large/medium — phrase negations explicitly at the end of the prompt (e.g. ", no large breasts, no cleavage, realistic subtle proportions"). This pushes Flux away from its bias more reliably than positive descriptors alone. Pair with slim/petite/athletic body types for best consistency.
Small–medium / A–B	small-to-medium breasts, modest B-cup, petite chest, subtle cleavage	Works best on slim/petite bodies
Medium / B–C	medium breasts, average-sized breasts, natural C-cup, well-proportioned bust	Easiest range — default bias often lands here
Full / C–D	full breasts, generously sized bust, prominent D-cup breasts, voluptuous but realistic	Very reliable
Large / DD–F	large breasts, DD-cup, ample cleavage, heavy bust, voluptuous chest	Very strong response — easy to get
Very large / G+	huge breasts, massive bust, enormous chest, breasts bigger than head	Works, but often becomes cartoonish unless you add "realistic physics", "natural sag"
