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

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).

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)
