For the first time in more than five years, OpenAI is launching a new open language model that appears to be state-of-the-art.

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.

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.
