After months of requests by developers, and plenty of trolling from the larger AI community, OpenAI has finally released an open model.<\/p>\n\n\n\n
OpenAI has released two open-weights models. The GPT-oss-120b is a large open model designed to run in data centers and on high-end laptops and desktops. The GPT-oss-20b is a medium-sized open model that can run on most desktops and laptops. The models are supported by the Apache 2.0 license, allowing developers to build freely on them. Both models are reasoning models.<\/p>\n\n\n\n
“Gpt-oss is a big deal; it is a state-of-the-art open-weights reasoning model, with strong real-world performance comparable to o4-mini, that you can run locally on your own computer (or phone with the smaller size). We believe this is the best and most usable open model in the world,” OpenAI CEO Sam Altman said <\/a>on the release.<\/p>\n\n\n\n The models are designed for agentic tasks, and leverage powerful instruction following, including web search and Python code execution. Users can adjust the reasoning effort in the models to low, medium or high. The models can also be customized to specific use-cases with full-parameter finetuning.<\/p>\n\n\n\n In a demo, OpenAI showed off the model being run on a laptop, and controlling the user’s screen.<\/p>\n\n\n\n
