Name: FLUX.2 [pro]
Author: Black Forest Labs

FLUX.2 [pro] is the production workhorse of the FLUX.2 family. It shares the same 32B rectified flow transformer and Mistral-3 24B VLM architecture as FLUX.2 Dev, but runs on Black Forest Labs' optimized infrastructure with faster inference and better quality tuning. It ranks #7 on LM Arena with a score of 1153 - four points above Dev, and only 15 below Max. At $0.03 per megapixel of output, it costs less than half of Max while delivering production-grade results.

TL;DR

Same 32B + 24B VLM architecture as Dev and Max, but tuned for production speed-to-quality ratio
LM Arena rank #7 (score 1153) - between Dev (#9) and Max (#4)
$0.03/MP output - less than half the cost of Max ($0.07/MP)
4-8 second generation, up to 4MP resolution
API-only (no open weights) - commercial use included in API pricing
Multi-reference, editing, and text-to-image in one model

Pro occupies the cost-performance sweet spot. It is 4 ELO points better than Dev at 2.5x the price, and 15 points behind Max at less than half the cost. For teams running thousands of generations per day, the $0.04 per-image savings vs. Max adds up fast.

Key Capabilities

Production-Grade Quality

Tuned for consistent, commercially viable output. Character faces, product photography, and marketing materials come out clean enough for direct use in campaigns and listings. The quality gap vs. Max is perceptible in side-by-side comparisons but rarely matters in production contexts.

Multi-Reference and Editing

Full support for combining up to 10 reference images, single-reference editing, style transfer, and inpainting - same as Dev and Max. The VLM integration enables contextually aware edits that understand spatial relationships and material properties.

Commercial API

Unlike Dev's non-commercial open weights, Pro's API pricing includes full commercial rights. No separate license negotiation required - you pay per megapixel and own the output.
