picoDiffusion is licensed under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International licence (CC BY-NC-SA 4.0).

In plain language, this means:

• You can use it. Run it, learn from it, tinker with it, break it, fix it.
• You can share it. Give it to friends, fork it, post it somewhere.
• You can modify it. Change the code, add features, make it yours.
• You must give credit. If you share it or a modified version, credit lacquerlabs and link back to the original project.
• You cannot sell it. No charging for it, no wrapping it in a paid product, no "I made this" followed by a price tag.
• Same licence forward. If you modify it and share your version, it has to use the same licence.

The full licence text is available on a separate page.

picoDiffusion is provided as-is, without warranty of any kind, express or implied. This includes, but is not limited to, warranties of merchantability, fitness for a particular purpose, and non-infringement.

In plain language: we built this, we think it works well, and we use it ourselves. But we make no promises that it will work perfectly on your system, that it will not break, or that it will do exactly what you expect. Software is complicated and hardware varies.

You use picoDiffusion entirely at your own risk. We are not responsible for:

• Any damage to your hardware (though the tool does not do anything that should cause hardware damage under normal use)
• Any data loss
• Any content generated by the models you choose to run
• Any consequences of exposing the tool to a network (which you should not do — see below)
• Any issues arising from third-party models, LoRAs, or VAEs you download and use

We do not indemnify you against any claims, damages, or losses arising from your use of picoDiffusion. You are responsible for how you use this tool and what you generate with it.

The images you generate are produced by AI models that you choose to download and run. We do not create, curate, or control those models. The content they generate is your responsibility.

If you use generated images commercially, check the licence of the specific checkpoint you used. Each model has its own licence terms set by its creator. We have no involvement in or control over those terms.

picoDiffusion depends on open-source libraries including PyTorch, HuggingFace Diffusers, FastAPI, and others. Each of those has its own licence and its own terms. We do not warrant the behaviour of those libraries. We just use them, same as you.

Checkpoint, LoRA, and VAE files are created and distributed by third parties. We recommend downloading .safetensors files rather than .ckpt files, because the safetensors format cannot execute arbitrary code. Older .ckpt files use Python pickle, which can contain and execute arbitrary code when loaded. Download model files from sources you trust.

We may update this disclaimer at any time. If you are using picoDiffusion, it is your responsibility to check back occasionally. We will not send you a notification because we do not have your email address, we do not want your email address, and honestly we would probably forget anyway.
