I've been playing around with OpenAI's gpt-oss:20b the last couple of days. As the company's first open-source model, it's the first chance we've had to try it out without going through the API or a tool like ChatGPT or Copilot.
It's based on GPT-4 and has, so it says, a knowledge cutoff of June 2024, which actually bests some of the other open source models out there right now. But it can also use web search to fill in some gaps, if you wish.
