FLUX.2 is the go-to model when you need your prompt followed precisely. Unlike Midjourney, which interprets and embellishes, FLUX.2 renders exactly what you describe — every element, spatial relationship, and style directive is respected. This makes it the strongest choice for concept art with specific compositions, multi-subject scenes, and illustrations that need to match a creative brief.
FLUX.2 is trained on natural language, not the comma-separated keyword style used by older diffusion models. Instead of "fantasy forest, mushrooms, glowing, blue light, fox, detailed," write: "A mystical forest at twilight where bioluminescent mushrooms cast soft blue light on ancient tree roots, with a small fox watching from behind a mossy rock." The more sentence-like your prompt, the better FLUX.2 understands spatial relationships between elements.
FLUX.2 doesn't have style presets like Ideogram or Midjourney. Instead, specify the artistic medium directly in your prompt: "oil painting with visible brushstrokes," "watercolor illustration on textured paper," "cel-shaded digital art," or "charcoal sketch on rough paper." This single phrase has more impact on output style than any other part of the prompt.
Aspect ratio shapes the composition more than you'd expect. Use 2:3 or 3:4 portrait for character art (gives room for full body + environment), 16:9 for landscape panoramas, and 1:1 for centered portrait close-ups. FLUX.2 adjusts its composition strategy based on the ratio — a character prompt in 16:9 will naturally include more environmental context.
FLUX.2 is highly sensitive to prompt changes — even swapping one adjective produces a noticeably different image. Use this to your advantage: generate a baseline, then tweak one variable (lighting, color palette, camera angle) per generation. Place multiple Image nodes on the Martini canvas to compare results side by side.
Demonstrates FLUX.2's strength: multiple specific elements (mushrooms, fox, roots) are all rendered with correct spatial relationships. Try changing "digital painting" to "watercolor" or "charcoal sketch" to see instant style shifts.

The natural-language structure "hands covered in clay" and "light streaming through dusty windows" guides FLUX.2 to render these specific details. Keyword-style prompts would lose these relationships.

"Isometric perspective" is a technical term that FLUX.2 interprets accurately, unlike models that default to natural camera angles. Good for architectural or infographic-style art.

FLUX.2 has no quality sliders or style presets — the prompt itself is your only control surface. Invest time in prompt wording rather than looking for parameter tweaks.
For character art, always specify the character's pose and expression in words. FLUX.2 follows pose descriptions ("arms crossed, looking over shoulder") more literally than any other model.
Include both subject and environment in every prompt. FLUX.2 rarely invents a good background on its own — "a knight in a forest" gets a bland background, but "a knight on a moss-covered stone bridge over a misty ravine" tells a story.
FLUX.2 images have a distinctive "clean" look — precise lines, accurate colors, and well-separated elements. Compared to Midjourney (which adds dreamy, painterly effects), FLUX.2 output looks more like a professional digital illustration. Text rendering is among the best, though Ideogram V3 is still superior for text-heavy designs. Generation takes 5-10 seconds.

Midjourney v7 is the most aesthetically opinionated image model available. Where other models faithfully reproduce your prompt, Midjourney actively interprets it — adding dramatic lighting, compelling composition, and artistic flair that transform simple descriptions into gallery-worthy images. This makes it ideal for concept art, illustration, and any project where visual beauty matters more than literal accuracy.

Ideogram V3 is the only AI model that reliably renders readable text inside images. Every other model — FLUX, Midjourney, GPT Image — struggles with text accuracy, often producing garbled letters. Ideogram V3 solves this, making it the clear choice for poster art, book covers, logo concepts, infographics, and any visual design where typography is part of the composition.
View guideNano Banana 2 is Martini's default image model and the best all-rounder for most users. It supports both text-to-image and image-to-image editing, accepts up to 10 reference images, outputs at up to 4K resolution, and costs as little as 10 credits per image. Where Midjourney prioritizes aesthetics and FLUX prioritizes prompt fidelity, Nano Banana 2 balances both — producing photorealistic, detailed images that closely match your description.

GPT Image 1.5 is built on OpenAI's language model architecture, giving it the deepest natural language understanding of any image generator. While FLUX and Midjourney interpret prompts as visual keywords, GPT Image 1.5 reads them as full sentences — understanding context, metaphor, spatial relationships, and narrative intent. This makes it the best choice for complex scenes with specific compositional requirements, abstract concepts, and multi-element illustrations.
