README:

flux-fine-tuner

This is a Cog training model that creates LoRA-based fine-tunes for the FLUX.1 family of image generation models.

It's live at replicate.com/ostris/flux-dev-lora-trainer.

It also includes code for running inference with a fine-tuned model.

Features

• Automatic image captioning during training
• Image generation using the LoRA (inference)
• Optionally uploads fine-tuned weights to Hugging Face after training
• Automated test suite with cog-safe-push for continuous deployment
• Weights and biases integration

Getting Started

If you're looking to create your own fine-tuned model on Replicate, you don't need to do anything with this codebase.

Check out these guides to get started:

👉 Fine-tune Flux to create images of yourself

👉 Fine-tune Flux with an API

Contributing

If you're here to help improve the trainer that Replicate uses to fine-tune Flux models, you've come to the right place.

Check out the [contributing guide](CONTRIBUTING.md) to get started.
