ChatGPT maker OpenAI is launching two open-source models (gpt-oss-120B and gpt-oss-20B), which it claims outperform similarly sized models on reasoning through complex tasks.
The US frontier AI firm said the two models, called gpt-oss models, were its “most capable” open-source models to date.
The launch of OpenAI’s open source models has been highly anticipated, along with the expected launch of GPT-5.
OpenAI founder Sam Altman has previously tweeted about a delay to the release of its open-source model.
Altman said: "We're excited to make this model, the result of billions of dollars of research, available to the world to get AI into the hands of the most people possible. As part of this, we are quite hopeful that this release will enable new kinds of research and the creation of new kinds of products.
"Going back to when we started in 2015, OpenAI's mission is to ensure AGI that benefits all of humanity. To that end, we are excited for the world to be building on an open AI stack created in the United States, based on democratic values, available for free to all and for wide benefit."
The new open-source models mark the first open-source models for OpenAI since 2019 and put it up against the likes of Meta’s Llama models and Mistral’s AI models.
It also comes as Chinese open-source models increasingly gain traction.
Unlike closed models, open-sourced models are available to developers, so they can build on top of them to improve their own products and tools.
OpenAI said the two open-source models were trained using a mix of reinforcement learning and techniques informed by OpenAI’s most advanced internal models, including o3 and other frontier systems.
OpenAI said the two open-source models outperform similarly sized open models on "reasoning tasks, demonstrate strong tool use capabilities, and are optimised for efficient deployment on consumer hardware".
On the virtues of releasing open-source models, OpenAI said they give developers a “wider range of tools to accelerate leading-edge research, foster innovation and enable safer, more transparent AI development across a wide range of use cases”.
The models also lower barriers for use in emerging markets, OpenAI said.
The models will be available for developers in Europe and other countries to freely download and run locally.
