Ideogram 3 vs. FLUX.2 — text inside images, done right

Posters, logos, ads, memes — any image with legible text is a special case. Ideogram and FLUX.2 both do it well. Here is who wins what. Before using AI-generated marks commercially, do a basic USPTO search (or ask a lawyer) — a Swoosh on a shoe is still a Nike problem regardless of who rendered the pixels.

Text in images used to be a mess

If you tried to generate a sign that said HAPPY BIRTHDAY in 2023, you got HAPPP BURTHDY or worse. By 2025 the typography problem was mostly solved by two specialists: Ideogram (founded explicitly to fix the problem) and FLUX (inherits solid text rendering from the diffusion transformer research lineage).

Head to head on text

Dimension	Ideogram 3.0	FLUX.2 Pro
Text accuracy	Best in class — rarely misspells	Excellent, occasional digit slip
Typography control	Fonts, kerning, layouts are strong	Good, more photoreal framing
Photoreal quality	Clean, product-style	Photorealistic, broader aesthetic
Per-image cost	$0.02 via API	$0.05 via API
Access	Web + API	API, fal.ai, Replicate
Best use case	Logos, social posts, signs	Mockups, ads, photoreal with text

Pick Ideogram when

You are making logos or wordmarks where every letter has to be perfect
You need multiple variations of a poster with different headlines
You want the cheapest per-image cost ($0.02)

Pick FLUX.2 Pro when

You need photoreal context around the text (product in hand, billboard in city)
You are already using FLUX for broader image generation
Aspect ratio flexibility matters (FLUX handles anything)

A poster workflow

import requests

# Ideogram API
headers = {"Api-Key": os.environ["IDEOGRAM_API_KEY"]}
payload = {
    "image_request": {
        "prompt": "concert poster, bold sans-serif headline 'MIDNIGHT OAK', below it in small italics 'Saturday March 14, The Vintage Room, 21+'",
        "aspect_ratio": "ASPECT_2_3",
        "model": "V_3",
        "style_type": "DESIGN"
    }
}
r = requests.post("https://api.ideogram.ai/generate", json=payload, headers=headers)
image_url = r.json()["data"][0]["url"]Two nested objects in the payload, one style_type for design work — Ideogram will preserve exactly that headline text.

What was the primary reason Ideogram was founded?
1. To generate video content from text prompts
2. To fix the problem of text rendering in AI images
3. To create photorealistic product images
4. To compete with Midjourney on artistic style
A designer needs to generate a logo where every letter must be perfect. Which model should they pick?
1. FLUX.2 Pro because it handles aspect ratios better
2. Ideogram 3.0 because it has the best typography control

4. Stable Diffusion 3.5 because it is open source
Which model inherits its solid text rendering from diffusion transformer research?
1. Stable Diffusion
2. FLUX
3. DALL-E
4. Ideogram
A marketing team wants to create a billboard ad showing a product in a realistic city scene with text overlay. Which model is the better choice?
1. Ideogram because it rarely misspells
2. Ideogram 3.0 because it is cheapest
3. Stable Diffusion because it is open source
4. FLUX.2 Pro because it excels at photoreal context with text
What issue does FLUX.2 Pro occasionally have that Ideogram 3.0 does not?
1. Creating inconsistent aspect ratios
2. Misspelling entire words
3. Generating blurry images
4. Slipping digits in numbers
Which platform is NOT listed as an access point for FLUX.2 Pro?
1. Ideogram's website
2. Replicate
3. fal.ai
4. API directly
A student creates an AI-generated image of a Nike swoosh on shoes and wants to sell the designs. What does the lesson warn?
1. It could still be trademark infringement regardless of who rendered the pixels
2. It is fine since the AI created it
3. It is legal if you change the color
4. It only matters if the shoes are physically printed
Which term from the lesson refers to the spacing between individual letters in text?
1. Wordmark
2. Aspect ratio
3. Photorealism
4. Kerning
For generating multiple variations of a poster with different headlines, which model is recommended?
1. FLUX.2 Pro because of its photoreal quality
2. Midjourney because of its artistic style
3. Ideogram 3.0 because it is best for multiple poster variations
4. Stable Diffusion because it is free
What does the lesson recommend doing before using an AI-generated logo commercially?
1. Do a USPTO trademark search or ask a lawyer
2. Change at least three elements
3. Wait 30 days to see if anyone complains
4. Post it on social media for feedback
Which model is described as having cleaner, product-style images rather than broad photorealism?
1. FLUX.2 Pro
2. Ideogram 3.0
3. Stable Diffusion 3.5
4. All models have equal photoreal quality
The lesson mentions a specific example: a coffee shop storefront with an A-frame chalkboard. Which model will 'nail the full text'?
1. Midjourney before V8
2. Ideogram 3.0
3. FLUX.2 Lite
4. Stable Diffusion 3.5
What does the term 'wordmark' mean in the context of this lesson?
1. A watermark on an image
2. A searchable database of words
3. A written email signature
4. A logo that consists primarily of text/words
Why might a user already using FLUX for general image generation choose to stick with FLUX.2 Pro for text tasks?
1. They want consistency across their workflow and FLUX handles text well enough
2. FLUX is the only model that can generate text
3. FLUX is more expensive so it must be better
4. Ideogram does not work with APIs
