Model overview

The flux-dev-lora is a version of the flux-dev text-to-image model from Black Forest Labs that supports fast fine-tuned LoRA inference. This model is designed to provide a faster and more efficient way to generate images from text prompts compared to the original flux-dev model. It utilizes LoRA (Low-Rank Adaptation) technology to enable quick fine-tuning on specific datasets or styles, while still maintaining the high-quality image generation capabilities of the original model.

Similar models from Black Forest Labs include the flux-schnell-lora, which is optimized for speed, the flux-dev model, and the flux-schnell model, which is tailored for local development and personal use. Another related model is the flux-dev-lora created by Lucataco.

Model inputs and outputs

The flux-dev-lora model takes a text prompt as the primary input, along with optional parameters like aspect ratio, guidance, and image-to-image mode. The model can then generate one or more images based on the input prompt and other configuration settings.

Inputs

Prompt: The text description for the image to be generated.
Aspect Ratio: The desired aspect ratio for the generated image.
Image: An input image for image-to-image mode.
Prompt Strength: The strength of the input prompt when using image-to-image mode.
Num Outputs: The number of images to generate.
Num Inference Steps: The number of denoising steps to perform during the image generation process.
Guidance: The guidance strength, which controls the balance between the input prompt and the model's learned representation.
Seed: A random seed for reproducible generation.
Disable Safety Checker: An option to disable the model's built-in safety checker.
Go Fast: An option to enable faster predictions using a quantized model version.
Lora Scale: A scaling factor for the LoRA adaptation.
Lora Weights: The LoRA weights to use for fine-tuning the model.
Megapixels: The approximate number of megapixels for the generated image.
Output Format: The format of the output images (WEBP, JPG, or PNG).
Output Quality: The quality of the output images (0-100).
