The two new models from OpenAI are available under the Apache 2.0 license, a popular choice for open-weight models. With Apache 2.0, models can be used for commercial purposes, redistributed, and included as part of other licensed software. Open-weight model releases from Alibaba’s Qwen as well as Mistral also operate under Apache 2.0.

Developers rejoice—OpenAI has just released two new open-weight models. Unlike most of OpenAI’s models, these new products can be downloaded and used without needing to pay API fees to OpenAI. The models can even run locally on laptops and phones.

For the first time in five years, OpenAI has released two new free and open-source AI models that are lightweight and designed to be easily integrated into other software programs.
