Today, we released the Astra Assistants API, a new service designed for users and organizations that want additional control over their data. The system uses DataStax Astra DB to store messages, assistants, threads, runs, and files, and its vector functionality for retrieval augmented generation (RAG). It calls out to OpenAI for large language model-related tasks like embedding generation and chat completion. About 70% of the OpenAI API's endpoints are currently supported by the Astra Assistants API, with plans to add more in future releases.
