FLUX.2 [Klein]: Upcoming fully open-source model under Apache 2.0 license. Smaller and faster.

Multi-Reference Generation Breakthrough

FLUX.2 supports multi-reference conditioning of up to 10 images. This solves the "stochastic drift" problem—when generating the same character twice produces different results.

What This Means:

• Same actor across 50 ad variations without face morphing
• Product remains identical in beach, city, and studio scenes
• Character looks identical regardless of pose, lighting, or background

FLUX.2 Technical Capabilities

Resolution: Up to 4 megapixels (4MP). Professional print quality.

Text Rendering: Clean, readable typography with proper baseline alignment, kerning, and font weight that holds up at high resolution.
