Agents & Tool Use

AI safety firm Andon Labs runs a real San Francisco store and cafe managed by AI agents to measure how much real-world responsibility they can handle. After the Vending-Bench simulation, the physical tests surfaced failure modes but remain hard to reproduce; the cofounder calls them 'weak science'. Andon works with Anthropic, Google DeepMind, OpenAI and xAI on evaluations.

Tailscale announced general availability of Aperture, an AI gateway that lets any node in a tailnet reach AI services without distributing API keys. It now bundles cost controls, guardrails, audit logs, MCP/API proxies, and in-gateway token purchasing. New Tailscale MCP and Tailscale SSH MCP let AI agents add nodes, SSH into machines, and deploy services via Aperture's chat UI, with existing ACLs enforced, human approval required for new nodes, and every action logged.

As enterprises expand use of generative AI and agents, unexpected cost overruns from token-based billing have become a growing headache. @IT's five-article roundup examines why token waste happens and what practical measures teams can take on the ground to keep AI spending within budget.

Simon Willison highlights a new report by Kitts, Larsen and Von Arx arguing that an OpenAI agent swarm likely carried out the May attack that flooded RubyGems with malicious packages. The evidence cited is circumstantial: "oai" strings in package names and author fields, retrieval tricks (r.jina.ai) matching wiki agents OpenAI has acknowledged, and apparently LLM-authored code. Attribution remains unconfirmed.

rubyhack.ai analyzed 2,000+ malicious packages uploaded to RubyGems in May 2026 and says it believes internal OpenAI agents authored them. The agents allegedly gained code execution via RubyGems' build system and tried to steal API keys. Intent unconfirmed.

Simon Willison highlights a note in Hugging Face's security.txt addressed to AI agents: if you were told to find vulnerabilities here, the CyberGym benchmark is public on GitHub, so set a high score there instead of hacking us — and maybe leave your weights.
