Hermes 3 8B

In non-nerd speak

Who makes it: Nous Research. The files come from the maker's own Hugging Face account.

License: Llama Community License. Meta's own license. You can download and use it for free, but Meta sets the rules. The Open Source Initiative says it is not open source.

Business use: Yes for most businesses. If your products had over 700 million monthly users, you need a separate deal with Meta. You must follow Meta's use policy and show "Built with Llama" if you share it.

Training data: We have not found a full public data release. Not yet checked in depth.

Will it run on my computer?

Pick a computer with at least 8 GB of memory. On a Mac, that is the unified memory. On a PC, a graphics card with that much VRAM is fastest. A PC with only normal RAM will also work, just slower.
