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.

It’s the first such models it’s launched in over five years, as pressure in the US grows to respond to China’s dominance in open models.

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.
