Most agents demo look great. You type a request, the agent calls a few tools, and a clean answer comes back. Then real users show up with a real data, and things break in ways you never tested. The agent picks the wrong tool, loops on a failling API, leak data it should not see, […] The post How to Evaluate AI Agents For Enterprise appeared first on Analytics Vidhya .

Google has introduced Gemini 4 Hydrogen, its latest AI model designed for faster execution, coding, and agentic workflows. Released on November 12, 2026, the model is rolling out across Google Search, the Gemini app, and developer tools. Alongside it, Google introduced Antigravity Orchestrator, which can switch between Hydrogen and a more powerful reasoning model within […] The post Gemini 4 Hydrogen: Hands-On Review appeared first on Analytics Vidhya .

arXiv:2611.15189v1 Announce Type: new Abstract: Document editing is among the most common knowledge-work tasks, yet existing benchmarks for evaluating autonomous agents on Word document editing provide fully specified attribute-modification instructions. They do not evaluate agents' ability to infer the appropriate attributes from document context, a capability essential in real-world editing where users expect consistency without spelling out every attribute. We introduce WordInferBench, a…

arXiv:2611.15178v1 Announce Type: new Abstract: Reinforcement learning sharpens LLM reasoning, but parameter updates are expensive, forgetful, and opaque; training-free libraries swap gradients for a textual store but still use trajectory-level, correlation-based admission and flat structure. To address both, we propose HyperSkill, a Training-Free Omnimodal GRPO framework that keeps the backbone frozen and replaces gradient updates with auditable edits to a Hypergraph-Indexed Skill-Library,…
