JoliGEN
JoliGEN trains custom GAN and diffusion image-to-image models while preserving masks, labels and class annotations.
Pick JoliGEN when your annotations are the asset you cannot lose and you can put GPUs plus an ML engineer behind it. The semantics-conservation angle is the real draw: documented BDD100K runs keep label boxes through day-to-night and clear-to-snow, with object insertion and removal on FFHQ and VITON-HD. Pass if you need a hosted service or a result today.

Skip JoliGEN if you have no ML engineer to configure training runs and no GPU capacity of your own, and you just need images out of a browser prompt box today.
Running training yourself means paying for GPU hours directly — multi-GPU runs on BDD100K-scale datasets are where your cloud bill actually lands, not in the toolkit itself
JoliGEN is open-source infrastructure, so your real budget line is GPU compute and ML engineer time rather than a licence fee. That makes it cheap next to commercial generative-image platforms that charge per seat or per image, but expensive next to simply not training a model at all. Budget for the training cluster, not the tool.

What is JoliGEN?
JoliGEN — JoliGEN trains custom GAN and diffusion image-to-image models while preserving masks, labels and class annotations. Best for Computer vision teams augmenting datasets while keeping labels and masks intact, Enterprise R&D groups training custom image-to-image models on proprietary data, AR and virtual try-on work needing realistic object insertion or removal. Pricing not published.
JoliGEN is Jolibrain's open framework for training your own image-to-image generative models instead of prompting someone else's API. It covers both GAN and diffusion (DDPM) architectures across unpaired and paired translation, and the whole design leans on semantics conservation: conditioned generators, bags of discriminators, and configurable losses so output keeps image and object classes, masks and existing dataset annotations while style, weather or content changes. The documented results are concrete. Glasses removal with GANs, glasses insertion with diffusion on FFHQ, virtual try-on on VITON-HD, car insertion on BDD100K, satellite imagery inpainting with diffusion, Mario-to-Sonic translation that preserves the action, and day-to-night, clear-to-snow, clear-to-rainy and clear-to-overcast transforms on BDD100K that hold label boxes for cars, pedestrians and street signs. The workflow runs from dataset formats and multi-dataset loading through multi-GPU training, model export, inference and metrics, then onto serving via a bundled server with a REST API, a JoliGEN UI and Docker for reproducible setup. Code builds on pytorch-CycleGAN-and-pix2pix, CUT, AttentionGAN and MoNCE, with elements supported by the French National AI program Confiance.AI. This is a training toolkit with a serving layer for computer vision engineers and research teams, not a prompt box. Compared with commercial image-generation APIs, JoliGEN trades speed of first result for control over exactly what survives the transform. If your annotations are the asset you can't lose and you have GPUs plus an ML engineer, it is a serious option; for text-to-image in five minutes, look elsewhere.

Behind the verdict
Most image-generation tools are built to make pretty pictures. JoliGEN is built for the opposite problem: changing an image without breaking the thing your dataset depends on. That single design goal explains almost every choice here, from conditioned generators to bags of discriminators and configurable losses. We would reach for it when augmentation has to be label-safe. If you are stretching a self-driving dataset with snow, rain or night variants and your bounding boxes must still line up, the BDD100K style-transfer examples are the closest thing to a proof you will get. Same for simulation-to-reality work where metrics have to survive the transform. Object insertion and removal is the other strong use. Virtual try-on on VITON-HD, car insertion on BDD100K, glasses in or out on FFHQ - these are documented recipes, not canned demos, so you can retrain them on your own imagery. Be honest about the cost of entry. This is a command-line training toolkit with a large option surface. The docs even warn you to start with Quick Start rather than wade into the parameters. Budget for GPU time, a data pipeline, and someone comfortable debugging training runs. Where it bites: there is no hosted cloud where the vendor holds the GPUs, and no prompt-to-image path. You bring the infrastructure. Teams that just need a handful of synthetic images are paying a lot of setup for a small job. The closest alternative is a commercial image API or a general diffusion pipeline you fine-tune yourself. Those win on time-to-first-result. JoliGEN wins on controlling what stays fixed - and for label-dependent datasets, that is usually the whole ballgame.
Models under the hood
as of 2026-09-01
Limitations
- JoliGEN is a training framework, so it demands real technical work: the vendor's own navigation advises starting with Quick Start precisely because the option surface is large.
- You self-host, which means you supply the GPUs, and the docs assume familiarity with deep learning concepts rather than explaining them.
- The two documented tutorials (DDPM on VITON-HD, style transfer on BDD100K) are the guided ceiling; beyond them you are reading model, dataset, loss and inference docs.
- Integration with creative tools such as Photoshop is not documented in the scraped content, so moving outputs into a design workflow means building your own pipeline.
- The unit of output is a trained model, not a finished image, and the recorded example applications cluster around driving datasets, faces and satellite imagery.
- Metrics preservation is a documented strength for simulation-to-reality, but that guarantee applies to the specific pipelines described, not universally to every translation task you invent.

GeneratedReal-world workflow fit
Concrete scenarios for the personas JoliGEN actually fits — and what changes day-one when you adopt it.
You have a BDD100K-style labelled set and need night and snow conditions that do not exist in your data. You install JoliGEN with Docker, load the driving dataset through the documented dataloaders, and train a conditioned generator for day-to-night, then chain the generator for clear-to-snow.
Outcome: New training frames in night, snow, rain and overcast variants where the car, pedestrian and street-sign label boxes survive the translation.
You need glasses or garments placed realistically on faces and bodies. You follow the Quickstart GAN recipe to remove glasses from faces and the Quickstart DDPM recipe to add them on FFHQ, then adapt the DDPM tutorial on VITON-HD for try-on.
Outcome: A trained insertion or removal model you export and serve through the bundled REST API for your AR prototype.
Your simulator renders are domain-shifted from camera footage. You set up supervised or unpaired translation toward real imagery, using the documented metrics tooling to check that elements and metrics are preserved.
Outcome: Renders that look closer to real capture while the simulator's ground-truth elements and metrics still hold, so downstream detector evaluation stays valid.
Use cases
- Augment a labelled training set while keeping existing masks and object classes intact
- Insert or remove objects such as glasses or cars for AR and virtual try-on work
- Translate simulator renders toward photorealism without losing metrics or labels
- Convert day footage to night, snow or rain on BDD100K-style driving datasets
- Inpaint missing areas such as gaps in satellite imagery using diffusion
- Enrich a sparse test set or counter class imbalance with generated images
- Serve a trained image-to-image model behind a REST API for downstream apps
Setup time & first value
How long it actually takes to get something useful out of JoliGEN — broken out by persona, not the marketing-page minute.
With Docker, an experienced CV engineer can get from install to a first training run on a documented dataset in roughly half a day, and often faster if you copy the Quickstart GAN or DDPM recipe. Reaching a model that actually meets your metrics target is a multi-day tuning job, since the option surface is large and the vendor advises starting from Quick Start.
Switching to or from JoliGEN
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From pytorch-CycleGAN-and-pix2pix: JoliGEN builds on it, so existing dataset layouts and paired/unpaired setups map onto the documented dataloaders with modest rework
- →From CUT or AttentionGAN: those methods are part of what JoliGEN builds on, so porting means moving your config onto JoliGEN's model and loss options
- →From a hand-rolled PyTorch training script: re-express your dataloader and losses through the documented JoliGEN models and losses, then use the bundled server instead of writing your own inference route
- ↗To a commercial generative-image API: you lose annotation conservation unless the replacement exposes equivalent conditioning, so expect to add manual labelling back
- ↗To another self-hosted training framework: your dataset formats port cleanly, but exported JoliGEN checkpoints will not load directly and the model must be retrained
