How to Cut GenAI and Agent Token Spend Without Cutting Capability

The practical controls that reduce context, model calls, loops, and unit cost while preserving task quality. GenAI prototypes rarely fail a cost review because of one expensive prompt. They fail when that prompt becomes a workflow. A production agent may add system instructions, conversation history, memory, retrieved documents, tool definitions, tool results, reasoning, retries, validation

Now, defenders are embracing the prompt injection, too

Prompt injections, the malicious commands attackers embed into content to entice LLMs to follow them, have been attackers’ go-to tool for turning AI platforms against their users. A well-phrased command sneaked into an email or calendar invitation is often all it takes to cause the LLM to exfiltrate sensitive data or follow other harmful actions.

Simulating everything, sort of: The promise and limits of world models

Over the past few years, many of us have gotten a crash course in what we now call artificial intelligence—but really, it has mostly been a crash course in large language models. Increasingly, however, LLMs are no longer the only category of AI drawing high expectations, massive funding rounds, and significant research and product development.

VMware vSphere Build Numbers in 2026: An Operational Runbook for Version Drift and Patch Validation

Build numbers are easy to treat as trivia until they become the deciding factor in a support case, security review, failed upgrade, or lifecycle audit. Most teams know whether they are running “vSphere 8” or “vSphere 9.” Fewer teams can quickly answer the more useful operational question: Which exact vCenter and ESX/ESXi builds are running

The VCF 9.1 Upgrade Is an Operating Model Project, Not a Patch Window

TL;DR A VCF 9.1 upgrade should not be treated like a normal maintenance window where each team updates its component, checks a dashboard, and leaves. The sequence matters. The ownership model matters. The readiness evidence matters. For VCF 9.1, VCF Operations is not a side task after the platform upgrade. Existing Aria Operations instances must
