Your hardware powers the AI

3Start chatting
Once the model is loaded enjoy free, unlimited chat. All data stays local.
Why FreeWeights is different
Your chat stays 100% local and the service is free- powered by your own hardware.
Most web-based LLMs either charge an exorbitant subscription fee, or harvest your data. FreeWeights is different: after a one-time download, the model runs inside your browser, powered by your own device.
Modern open-source language models now rival the performance of state-of-the-art models from just a few years ago. That means there’s no need to pay for the latest and greatest, if your use case doesn’t require the most powerful models.
What you need
A modern browser, a few gigs of storage, and sufficient VRAM
Browser
FreeWeights works best on Chrome, Edge, Safari, or similar browsers with WebGPU support.
Storage/Cache
AI models can be large. Typical models require around 1-6GB of available cache, some even more.
Sufficient VRAM
Phones and older laptops should start with smaller models. Apple Silicon and other GPUs with dedicated VRAM can handle large models.
Why FreeWeights?
A simple way to try free, private AI chat
Some local AI tools are made for power users and require installs, setup steps, or command-line work. FreeWeights is meant to be easier: open the site, choose a model, and chat.

Frequently Asked Questions
Is FreeWeights really free?
Yes. FreeWeights is built around free open-source AI models. You do not need a paid chatbot subscription or an API key to try supported models in your browser.
Do I need to understand AI models to use it?
No. You can start with one of the smaller recommended models. If you want to learn more later, the app shows model size, memory needs, and device guidance.
Are my messages private?
FreeWeights is designed so your prompts and replies stay in your browser after the model is loaded. That is different from many web chatbots, where every message is sent to a company server for the AI to answer.
Does FreeWeights use the internet?
FreeWeights needs internet connectivity temporarily to download the model files. But, once the model is loaded, all inference happens offline and no internet connectivity is required.
What does "running on my device" mean?
It means your computer or phone does the work of generating the AI reply. The technical name is local inference. FreeWeights uses browser technology called WebLLM and WebGPU when your browser supports it.
Will every device run every model?
No. Browser support, graphics hardware, available memory, and model size all matter. FreeWeights includes model and resource guidance to help you choose.
