Open-source AI is now matching GPT-4 — and you can run it privately for free

This Reddit post discusses how open-source AI models have advanced to rival GPT-4-level performance and can be run locally for free using Ollama — a tool that lets users download and manage large language models with a single command. OpenAI's GPT-OSS models, released under a permissive Apache 2.0 license, give developers access to state-of-the-art open-weight LLMs completely free to use and run locally. Thanks to Ollama, users can run fully capable open-source AI models right on their own laptop or desktop, completely offline, completely private, and completely free — with no API costs, subscriptions, or data leaving their machine.
