Alibaba Cloud Announces the Tongyi Qianwen Large Model Has Passed the First Batch of Record-Keeping and Is Officially Open to the Public. Users Can Log in to the Tongyi Qianwen Website for Experience, and Corporate Users Can Access the Tongyi Qianwen API Through Alibaba Cloud. In April this year, Alibaba Cloud's Tongyi Qianwen began an invitation-only testing phase. More than 200,000 enterprise and institutional users applied for access to the testing, and partnerships have been established with OPPO, Dewu, DingTalk, and others. Alibaba Cloud will open-source a version of the large model with a larger parameter scale, hoping to collaborate with the entire industry to build an open-source ecosystem for large models.
