GPT0

AI that stays on your device.

GPT0 runs open AI models inside your browser. There’s no account to create and no charge per message.

Choose a model

Start small on a phone or a less powerful computer. Larger models need more memory and take longer to download.

Download once, then chat

The first load downloads model files. Your browser can keep them for later visits. Downloads can use a lot of mobile data, so Wi-Fi is a good idea.

Keep your conversations here

Prompts, replies, and text attachments are processed on your device. Saved chats stay in this browser profile. Export anything you want to keep before clearing site data.

Privacy and practical limits

GPT0 does not send your chat text or attached files to an AI service. The site host and model download providers receive ordinary connection information, such as your IP address, when serving the page or files.

Anyone using this browser profile may be able to open its saved chats. Browser storage is not a backup and may be cleared by you or your browser.

A compatible browser with WebGPU is required. Speed and model availability depend on your hardware. These models can be wrong, don’t browse the live web, and don’t run code or open apps for you.

GPT0 uses WebLLM. It is an independent project and is not affiliated with OpenAI.
