[Meta releases open source AI model, core cutting-edge technology remains closed source‌] On October 16th, Meta Platform Company is opening up the weight files of its Muse Spark open source model for developers to download and modify again, while retaining its most advanced AI technology from being made public. Meta chief AI officer Alexandr Wang said that in principle, the company will not open source the most powerful models, but will continue to open slightly lower-performance model versions to the developer community. The release of Muse Spark Open is one of Meta's initiatives to convert investment in the AI ​​field into actual revenue. The model is currently open to developers on multiple platforms such as Amazon SageMaker AI and Google Cloud Model Garden.
