Agentic MLLMs Systematically Fail to Refuse Harmful Requests When Using Tools
Safety guardrails break down specifically in tool-use agentic contexts. Operators running multimodal agents with tool access must add explicit refusal layers—chat-mode safety evaluations are insufficient.

Frontier math reasoning has crossed a qualitative threshold. Operators building scientific/research agents should re-evaluate capability ceilings; benchmark assumptions are now outdated.
