Image-only models available in Vercel AI Gateway

You can now access image-only models via Vercel's AI Gateway with no other provider accounts required. In addition to multimodal models with image generation capabilities that are currently available in AI Gateway (e.g., GPT-5.1, Nano Banana Pro, etc.), these image-only models are exclusively for image generation. The models include: Black Forest Labs:

• 
  FLUX.2 Flex: bfl/flux-2-flex
  
  
• 
  FLUX.2 Pro: bfl/flux-2-pro
  
  
• 
  FLUX.1 Kontext Max: bfl/flux-kontext-max
  
  
• 
  FLUX.1 Kontext Pro: bfl/flux-kontext-pro
  
  
• 
  FLUX 1.1 Pro Ultra: bfl/flux-pro-1.1-ultra

To use these models, set model to the corresponding slug from above in the AI SDK. These models support generateImage.


AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.
