Payment fraud detection combines rule-based systems, machine learning, and real-time monitoring to block unauthorized transactions. Learn about major fraud types, detection techniques, and prevention strategies.

An AI agent harness is the software infrastructure that wraps around a large language model (LLM) and enables it to act on tasks, not just respond to prompts. This article explains the core components—tools, memory, sandboxes, and guardrails—and how they enable reliable action through a reason-act-observe loop. It covers eight building blocks, common failure modes, and why harness design is critical for enterprise AI strategy.

Today, we’re announcing inline payload support for Amazon SageMaker AI Async Inference. Customers can now send inference payloads directly in the request body of the InvokeEndpointAsync API, removing the need to upload input data to Amazon Simple Storage Service (Amazon S3) before each invocation.

Amazon Quick introduces autonomous agents that work continuously, a prioritized activity feed, and cross-data source insights from a single question, helping users reclaim hours daily.

Databricks and NVIDIA are expanding their collaboration to deliver an end-to-end AI platform that accelerates model training, inference, and agentic AI development on governed enterprise data. New capabilities include Multinode training in AI Runtime, GPU support in Databricks Free Edition, Model Serving Enhancements, and support for NVIDIA technologies such as NVIDIA Agent Toolkit. Customers can leverage NVIDIA’s industry-specific AI frameworks directly within Databricks to accelerate use cases across healthcare, life sciences, supply chain, robotics, digital twins, and document intelligence.

GitHub Copilot is improving efficiency by reducing redundant context through prompt caching and deferred tool loading, and by introducing Auto model selection that routes tasks to the best-fit model based on intent and real-time health, saving credits without sacrificing quality.

Cloudflare is opening up its Agents SDK primitives for any agent framework to build on, with Flue as the first open-source framework targeting the SDK. Flue, built on the Pi harness, leverages Durable Objects for durable execution, dynamic code execution via Code Mode, and a virtual filesystem via @cloudflare/shell, enabling production-grade agent deployment.
