; }; FLUX.2 brings powerful image editing capabilities across the entire model family. Describe what you want changed in natural language — swap backgrounds, replace objects, transfer styles, adjust lighting — and FLUX.2 makes it happen while maintaining photorealism. All **FLUX.2** variants support multi-reference image editing, allowing you to combine elements from multiple source images into a single coherent result. ## Reference Images per Model | Model | Reference Images (API) | Reference Images (Playground) | | ---------------------- | ---------------------- | ----------------------------- | | **FLUX.2 \[max]** | Up to **8** | Up to **10** | | **FLUX.2 \[pro]** | Up to **8** | Up to **10** | | **FLUX.2 \[flex]** | Up to **8** | Up to **10** | | **FLUX.2 \[klein] 9B** | Up to **4** | — | | **FLUX.2 \[klein] 4B** | Up to **4** | — | | **FLUX.2 \[dev]** | Recommended max **6** | — | More reference images means more control. Use multiple inputs to maintain character consistency, combine furniture from different photos, or transfer styles — all in a single generation. ## Single Editing Example ## Multi-Reference Example Full editing documentation with API examples, parameters, and multi-reference techniques.
