3 Models Available
Design eye-catching social media visuals in seconds. Each guide covers platform-specific dimensions, styles, and prompt techniques for different AI models.
Ideogram
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.
Black Forest Labs
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.
Midjourney
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.
