In the digital age, misinformation spreads rapidly, making it increasingly difficult to ensure the integrity of information. AI presents new opportunities to support fact-checking and news classification. Giovanna Monti and Lucian Precup shared their insights from their work developing an AI-driven platform integrating search capabilities, an intelligent assistant and a RAG system.

Apache Flink is uniquely positioned to serve as the backbone for AI agents, equipping them with the powerful new tool of stream processing. At Berlin Buzzword 2025, Steffen Hoellinger discussed how Flink jobs can be transformed into “Agents”—autonomous, goal-driven entities that dynamically interact with data streams, trigger actions, and adapt their behaviour based on real-time insights.

Reproducibility in embedding benchmarks is challenging, especially with embedding models that are instructional and increasingly large. At #bbuzz, Isaac Chung explained how MTEB addresses prompt variability, scaling issues and large datasets to ensure fair and consistent scores, setting a standard for benchmarking embeddings.

RAG has revolutionised AI by merging search and generation. Agentic behaviour takes this search to the next level by enabling LLMs to make decisions and call tools. At Berlin Buzzwords 2025, Bilge Yücel discussed how agentic behaviour enhances pipelines, what it means for a system to act as an 'agent', and core concepts such as routing, tool calling and reasoning, along with a live demo.
