Is anything I type sent to a server?
No. OLMo 2 0425 1B Instruct runs on your own GPU inside the browser tab. The only network traffic is the one-time download of the model files from Hugging Face; your prompts and the answers never leave the device, and the chats are stored in this browser.
Which build of OLMo 2 0425 1B Instruct should I choose?
