OpenAI's GPT-5, the latest installment of the AI technology that powered the ChatGPT juggernaut in 2022, is set for an imminent release, and users will scrutinize if the step up from GPT-4 is on par with the research lab's previous improvements.

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.
