FLUX.2 produces the most photorealistic and compositionally precise social media imagery of any model on Martini. It cannot render text inside images (use Ideogram V3 for that), but for visual-first content — lifestyle flat-lays, product showcases, mood boards, scenic backgrounds — it consistently outperforms competitors. FLUX.2 has no style presets or quality sliders, so the prompt itself is your only creative control. This simplicity is an advantage: you focus entirely on describing what you see, and FLUX.2 renders it with minimal artistic interpretation.
FLUX.2 supports 1:1, 4:3, 3:4, 16:9, and 9:16. For social media, the ratio choice affects more than cropping — FLUX.2 adjusts its composition strategy based on the ratio. Instagram feed posts perform best at 4:3 (takes up more vertical space in the feed than 1:1, increasing engagement). Stories and Reels need 9:16. YouTube thumbnails and Twitter headers use 16:9. Choose the ratio before writing your prompt because the same scene description produces very different compositions at different ratios.
FLUX.2 is trained on natural language, not the comma-separated tag style that older models expect. For social media, this means you should describe the scene as if briefing a photographer: "A warm overhead shot of a morning coffee setup on a marble countertop — latte with rosetta art in a handmade ceramic cup, a croissant on a linen napkin, sunlight casting diagonal shadows, shallow depth of field." The more sentence-like and specific, the better FLUX.2 places each element relative to the others.
End your prompt with a style anchor that tells FLUX.2 what visual language to use. "Editorial lifestyle photography" produces clean, magazine-style imagery. "Moody product photography, dark background" creates premium e-commerce aesthetics. "Bright airy photography, pastel tones" matches wellness and beauty brands. This single phrase has more impact on the output than anything else — it sets the overall color palette, contrast, and mood.
Set the count to 2-4 to generate multiple variants from the same prompt. FLUX.2 introduces natural variation across outputs — slightly different compositions, lighting angles, and color balance. Place the Image nodes side by side on the Martini canvas to compare. Pick the strongest composition, then iterate by tweaking one element (swap "warm golden hour" for "cool blue hour") to refine toward your exact vision. FLUX.2 is the lowest-cost image model on Martini, so iterating is affordable.
Lifestyle flat-lay — the natural language structure ("latte art in a ceramic cup, open notebook with handwritten notes") tells FLUX.2 exactly how to arrange elements spatially. Adding "shallow depth of field" creates the blurred-edge look that performs well on Instagram. "4:3" takes up more feed space than square.

Before/after split — FLUX.2 excels at this format because it follows spatial instructions literally. "Left side" and "right side" with a "clean dividing line" produces an actual split composition. Most models would blend the two halves together. 16:9 works for Twitter, LinkedIn, and YouTube community posts.

Product showcase — the specific material details ("dark slate surface," "rain droplets for texture") and lighting direction ("dramatic side lighting creating long shadows") give FLUX.2 enough information to create a premium product shot without needing a real studio setup.

FLUX.2 has zero configurable parameters — no style presets, no quality sliders. The prompt is your only control surface. This means prompt quality matters more with FLUX.2 than with any other model.
4:3 outperforms 1:1 on Instagram feed posts — it takes up approximately 20% more vertical screen space, increasing the chance users stop scrolling. Use 1:1 only when you need a clean grid aesthetic on your profile.
For social media consistency, create a "style template" prompt suffix you reuse across posts: e.g., "warm editorial photography, shallow depth of field, pastel earth tones." This creates a cohesive feed aesthetic without any built-in style presets.
FLUX.2 is the lowest-cost image model on Martini with a "low" price indicator. Use it for high-volume social content where you need 10-20 images per session. Switch to Midjourney v7 when you need artistic flair for a hero post.
FLUX.2 produces the cleanest, most photorealistic social media imagery — precise compositions with accurate colors and well-separated elements. The trade-off is that it cannot render text inside images (letters come out garbled), so use Ideogram V3 for any graphic that includes headlines or captions. The ideal social media workflow uses both: FLUX.2 for visual-only posts (lifestyle shots, product photos, scenic content) and Ideogram V3 for text-heavy graphics (carousel covers, quote cards, announcements). For posts that need artistic, painterly effects rather than photorealism, switch to Midjourney v7.

Ideogram V3 is the only image model that reliably renders readable text directly inside generated images. This makes it the clear choice for social media graphics where typography is part of the design — Instagram carousel covers, YouTube thumbnails with bold titles, LinkedIn quote cards, and branded promotional graphics. Where FLUX.2 and Midjourney produce gorgeous imagery but garble any text you include, Ideogram V3 treats text as a first-class element, generating clean, stylized typography that looks like it came from a design tool.

Midjourney v7 creates the most aesthetically striking social media visuals of any AI model. Every generation produces 4 images simultaneously, giving you a curated set to choose from — a workflow that mirrors how professional creative teams select hero shots. Its natural tendency to "beautify" outputs makes it ideal for mood boards, brand aesthetics, and visually rich posts where artistic impact matters more than photorealistic accuracy. Midjourney v7 is classified as a "high" cost model (3 credits/image on Fast, 6 on Turbo), so it pairs well with cheaper models for drafting: use FLUX.2 for volume exploration, then switch to Midjourney for the final hero image.
