Prepared for researchers and practitioners who want to keep up with the fast moving world of autonomous AI agents. This issue delivers a deep dive into the latest papers and industry updates, emphasising new capabilities, open challenges, and future directions.

What a week for AI agents! Researchers introduced frameworks that teach language models to use tools via reinforcement learning, optimise their planning to reduce latency and cost, and learn from their mistakes through structured self reflection.

Evaluation platforms grew more realistic, requiring agents to operate in asynchronous, dynamic worlds or to perform actual occupational tasks. Domain specific agents automated entire research pipelines in health informatics and other verticals, while multi agent architectures improved reasoning quality without ballooning token usage.

Beyond academia, top labs and companies rolled out open source frameworks, memory tools and integrations that signal a maturing ecosystem. The through line of these developments is clear: the field is moving from controlled benchmarks to real world deployments, focusing on reliability, efficiency and adaptability.

Below, we survey the most impactful research papers and recent updates, explaining the core innovations, why they matter and how they fit into the broader trajectory of agentic AI.

Note: This is an XXL issue with even more content than usual. More frontier research, more practical scenarios, more domain-specific applications - more everything.
