Notice

Remember when interacting with a model you are experimenting with AI, so content mistakes are possible. The feature is subject to various limits (including requests per minute, requests per day, tokens per request, and concurrent requests) and is not designed for production use cases. GitHub Models uses Azure AI Content Safety. These filters cannot be turned off as part of the GitHub Models experience. If you decide to employ models through a paid service, please configure your content filters to meet your requirements. This service is under GitHub's Pre-release Terms. Your use of the GitHub Models is subject to the following Product Terms and Privacy Statement. Content within this Repository may be subject to additional license terms.
