Generative AI agents, pivotal in today's AI revolution, are categorized into reactive and proactive types, with the latter being more transformative due to their ability to anticipate needs and act on evolving contexts rather than just responding to prompts. Proactive agents, unlike reactive ones, require real-time context to function effectively, as outdated data can lead to flawed decisions, missed opportunities, and eroded trust. DeltaStream is introduced as a solution to provide this real-time context by continuously ingesting and processing data from various sources, ensuring AI agents have access to the most current and comprehensive information. This enables the development of autonomous agents capable of anticipating needs and driving outcomes, heralding a future where AI operates with up-to-the-second awareness.
