Pricing

Usage-based

Check official pricing

FLUX 3 Image Klein API generation and editing cost US$0.008 per 768-square output, $0.009 at 1K, $0.011 at 1.5K, $0.014 at 2K and $0.036 at 4K. Local weights are free to download under the FLUX Kommunity License; qualifying commercial output use requires gross annualized revenue strictly below US$5 million including affiliates and compliance with its conditions. Commercial self-hosting at or above that threshold requires a separate license. Commercial weight distribution is outside the free grant; paid API/SaaS hosting needs case-specific clarification. FLUX.2 Klein 4B remains Apache 2.0. Other FLUX models and third-party services have separate prices and terms.

Why people pick it vs where it falls short

Why people pick it

  • Hosted and downloadable model options
  • Klein supports reference-guided generation, editing and layout controls

Where it falls short

  • Local setup, memory use and speed vary by model format, runtime and workflow
  • Klein edits can change unintended details; independent quality evidence remains limited
  • Model licenses differ, and FLUX 3 Klein commercial use has revenue and use restrictions
  • Not a full end-to-end design suite for non-technical production teams
