The Cube AI API has significantly reduced its pricing for token usage due to the availability of more efficient models like Claude 3.5 Sonnet and GPT-4o, now allowing five requests per CCU for all Cube Cloud customers. The API, already enabled for paying customers, includes features like Value Search to improve data access and interaction by indexing specific dimensions for more effective queries. Customers can also bring their own LLMs to further customize and potentially reduce costs. Additionally, Cube has launched a Slack app to facilitate stakeholder interaction with the AI API, providing a seamless way for users to query and receive data through direct messaging, with options for follow-up questions and feedback.
