flux-2-klein

What problem does it solve?

It helps you generate high-quality images with Black Forest Labs’ Flux 2 Klein by providing model-specific prompting guidance and invoking the correct RunComfy endpoints for faster creative iteration.

Core Features & Use Cases

• Low-latency concepting vs polish workflows: Uses Flux 2 Klein 4B for rapid iteration (around 4 steps) and Flux 2 Klein 9B for higher-fidelity refinement (around 25 steps).
• Subject-first prompt patterns: Improves output consistency by using the model’s preferred declarative structure and specificity-focused guidance.
• Multi-reference style guidance: Supports up to 4 reference images in a single call to maintain consistent brand styling and composition.
• Smart routing guidance: Recommends when to switch to Flux 2 Pro, Seedream 5, GPT Image 2, or Nano Banana Pro based on quality, text, aspect, and resolution needs.
• Hands-off execution via RunComfy CLI: Runs the correct API request and downloads generated outputs from approved RunComfy hosts.
