Workflow on Mivo
Open Generate Studio and switch to the AI Image tab. Select FLUX.2 Flex from the model list, choose your aspect ratio and resolution, then write your prompt. For image-to-image editing, upload reference images and describe the transformation you want.
Generate multiple images in parallel with different seeds for variety. The studio supports up to 5 concurrent jobs per model, so you can iterate quickly and pick the best result.
Once satisfied, download your image or publish it directly to your Mivo profile. All generated images are archived in your generation history for easy access.
Prompt guidance
FLUX.2 Flex responds well to descriptive, detailed prompts. Include subject, setting, lighting, mood, camera angle, and style references. Be specific about the final image you want, not the process of creating it.
For image-to-image editing, describe what you want to change or enhance. Reference images provide visual context, so your prompt should focus on the transformation rather than restating what is already in the images.

Best practices
Start with 1K for drafting and iteration. It is faster and cheaper, allowing you to explore multiple concepts before committing to higher resolution output for final production.
For multi-image reference editing, provide diverse angles and styles of your subject. The more visual context the model has, the better it can blend references into a cohesive output. Use all available reference slots when possible.
Always verify text rendering in generated images. While FLUX.2 Flex has good text capabilities, complex phrases and non-English text may still require post-processing with image editing tools for pixel-perfect results.
Pricing
14 credits for 1K, 25 credits for 2K per image — premium edit-focused model. Credit-based pricing on Mivo offers significant savings compared to accessing the Black Forest Labs API directly.
