What Is FLUX.2?
FLUX.2 is the most consistently praised model for realism, particularly skin texture, metal and glass, and natural light falloff. It is also the most tunable model on this site: Guidance, Steps, Strength and Safety Tolerance are all exposed, so if you are willing to turn knobs you can get closer to what you actually pictured.

FLUX.2 Settings Explained
Guidance
How hard the model sticks to the prompt. 2.5–3 for realism, 4+ for graphic and illustrative work.
Steps
28 is the value-for-money knee. Pushing to 50 rarely pays off.
Image Strength
Image-to-image only. 0.3–0.5 keeps the original composition; above 0.8 is effectively a repaint.
Safety Tolerance
Shifts the content filter threshold. Keep the default for commercial assets.
The panel above shows only the parameters FLUX.2 actually supports. Switch versions and unsupported controls disappear rather than sitting there doing nothing.
FLUX.2 Prompt Examples
Photoreal portrait
Portrait of a woman in her 30s, natural skin texture, soft window light from the left, 85mm lens, shallow depth of field, muted color grading
Keep Guidance around 2.5–3; higher makes skin look fake.
Material study
A brushed titanium watch on dark slate, single hard light source, sharp specular highlights, macro detail
FLUX.2 Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for FLUX.2, so this page shows no scores. We do not publish numbers we have not measured.

- GPT Image vs FLUX.2 — the same prompt, side by side
FLUX.2 Limitations
- In-image text is weaker than Ideogram or Nano Banana Pro
- Many parameters means a steeper learning curve
- High Guidance quickly produces a plastic look

Can FLUX.2 render text in the image?+
Short headlines, yes. For long copy or non-Latin scripts, switch to Ideogram 3 or Nano Banana Pro.
What Guidance value should I use?+
2.5–3 for realistic scenes, 4–5 for illustration. Fix the seed first so you can compare values fairly.
