Use Lumenfall image models inside llms.py - both the CLI and the web UI. Generate and edit images with any Lumenfall model in a single command.See the llms.py integration guide for setup and usage.General availability
Lumenfall is now generally available. Access all top models from the Artificial Analysis Text to Image and Image Editing leaderboards through a single, OpenAI-compatible API.Each model is backed by multiple providers with automatic failover and zero markup on model costs.Model features like requesting a specific output size or format are normalized across models and providers, so they always just work.OpenAI-compatible API
Multi-provider routing
- Six providers: Google Vertex AI, OpenAI, Replicate, fal.ai, Fireworks AI, and Runware
- Automatic failover when a provider doesn’t respond or returns an error
- Force a specific provider by prefixing the model slug (e.g.,
vertex/gemini-3-pro-image-preview)
Unified model behavior
- Feature emulation ensures all models behave consistently
- Request any size (e.g., “1920x1080”) and we map it to each provider’s and model’s expected format
- Output format conversion (PNG, JPEG, WebP, AVIF) across all providers
- Get responses as URL or base64 (
response_format), regardless of provider support
- Standardized error responses following OpenAI conventions
