Info Update (May 2025): We’ve released a faster version of the Flux trainer — try it here.
The FLUX.1 family of image generation models was released earlier this month and took the world by storm, producing images surpassing the quality of existing open-source models. The community quickly started to build new capabilities on top of Flux, and not long after the release we announced Flux fine-tuning support on Replicate.
Fine-tuning Flux on Replicate is easy: you just need a handful of images to get started. No deep technical knowledge is required. You can even create a fine-tune entirely on the web, without writing a single line of code. The community has already published hundreds of public Flux fine-tunes on Replicate, plus thousands of private fine-tunes too.
One of the most exciting things about Flux is its capability to fine-tune on faces in a way that was not easily achievable with previous generations of open-source image generation models like Stable Diffusion or SDXL. Not since Dreambooth has it been this easy to get great results from just a handful of training images.
In this blog post I’ll walk you through the process of creating your own Flux fine-tune using images of yourself, so you can create novel and imaginative images of yourself as a superhero, a cartoon character, an adventurer, or just a regular person in a variety of interesting situations.
