Our approach to EU text provenance rules
OpenAI has published its technical approach to text watermarking under emerging EU AI provenance regulations, detailing where watermarks are applied in ChatGPT outputs and how detection works. Access to the detection API is initially gated to researchers. This is a notable policy-driven engineering commitment from a major lab, signaling that EU regulation is now shaping production system design.

Building advertising for the way people use AI
OpenAI is introducing a native visual ad format inside ChatGPT alongside expanded measurement, attribution partnerships, and brand suitability controls for advertisers. This marks a significant shift in ChatGPT's business model, moving beyond subscription and API revenue toward advertising. The format is designed to integrate with conversational context rather than replicate traditional display ads.

MLLMs Fail to Refuse when Using Tools Agentically
A study across three safety benchmarks finds that all tested open- and closed-weight multimodal LLMs exhibit substantially lower safety refusal rates when operating in agentic tool-use settings compared to standard non-tool settings, with refusal failure rates increasing up to 68.7% relative. The analysis is based on over 100,000 model responses and identifies two candidate mechanisms for the degradation. This is a concrete, empirically grounded safety finding directly relevant to anyone deploying agentic multimodal systems.

Proxy Confidence: Auditing Black-Box LLM Agents with a Surrogate's Log-Probabilities
This paper proposes using a parallel open-weight surrogate model to recover calibration signal for black-box LLM agents whose token probabilities are inaccessible via API. The surrogate scores the same context and proposed tool calls using techniques including teacher forcing and request-PMI, providing actionable confidence estimates before irreversible actions execute. The approach addresses a practical gap in agentic deployment where silent errors in tool calls have real consequences.
