Microsoft AI opens review on Humanist AI Code of Conduct

Microsoft AI has published a draft Humanist AI Code of Conduct, opening a six-week public consultation on operational constraints for model training and deployment. The draft serves as a technical manual defining system behaviour, operational boundaries, and oversight protocols across MAI frontier models. It builds on the division’s humanist superintelligence framework announced last November, establishing […]

Why MCP servers are becoming AI’s newest attack surface

As AI adoption gathers pace, so does the evolution of the infrastructure that supports it. New standards and connectors keep appearing, and the ones that catch on spread through the ecosystem within months rather than years. That speed strengthens what AI can do, but makes it very difficult for security teams to maintain sufficient protections.

OpenAI president urges enterprises to hasten AI security defences

OpenAI president and co-founder Greg Brockman warns that enterprise security teams face a compressed timeline to adopt AI defences. Brockman has published an account of what the company calls the “OpenAI-Hugging Face” incident, using it to argue that organisations need to uplevel their security practices with what he terms unprecedented speed. He writes that he

Bar chart comparing five AI models across three cybersecurity benchmarks. GLM-5.3 leads on CyberGym at 84.5 but trails Mythos 5 on ExploitBench and ExploitGym.

Reading Zhipu’s GLM-5.3 results past the headline number

Zhipu’s release note for GLM-5.3 contains a sentence that did not make it into most of the coverage. Describing its own cybersecurity results, the Beijing company writes that capability “is growing fastest exactly where we are furthest behind.” Zhipu, which also trades as Z.ai, is one of a handful of Chinese labs releasing models that compete with

Okta targets AI agent token costs with MCP scoping

Okta says identity-scoped Model Context Protocol (MCP) tool lists can reduce AI agent token costs. Each model call made by an AI agent can include schemas, names, descriptions and parameters for every tool exposed by a MCP server. Okta calls the resulting prompt overhead the “tool tax”: tokens consumed as a model considers tools, including

OpenAI aligns safety practices with EU AI Act’s GPAI Code

OpenAI has outlined how it aligns safety, security, and transparency work with the EU AI Act’s GPAI Code as enforcement approaches. The company has contributed to and endorsed the EU’s General-Purpose AI (GPAI) Code of Practice and the Code of Practice on Transparency of AI-Generated Content. Both emerged from multi-stakeholder processes. The GPAI Code sets

Zuckerberg details Meta’s personal AI superintelligence strategy

Mark Zuckerberg has published a WSJ op-ed that argues superintelligence must reach individuals, not just a handful of institutions. The Meta chief published the piece as a statement of company philosophy rather than a product announcement. It contains no release dates, no benchmark figures, no named models. What it does contain is an argument that

Meta, Microsoft, Nvidia, IBM, and others back open-weight AI

Two dozen companies and organisations signed an open letter urging US policymakers to protect open-weight AI models. The letter, published today (PDF), carries signatures from a list that spans direct commercial rivals and organisations with little obvious overlap in business model: Meta, Microsoft, Nvidia, IBM, Dell Technologies, CrowdStrike, Palantir, ServiceNow, Hugging Face, Perplexity, Mistral, Andreessen

Google’s Gemini 3.6 Flash targets enterprise agent token costs

Google has released Gemini 3.6 Flash and 3.5 Flash-Lite as new workhorses designed to cut latency and token costs for enterprise AI agents. The economics of running autonomous software agents inside a production environment come down to a fixed equation few vendors advertise directly. A model needs to reason through a multi-step task competently, but

Examining Google DeepMind’s AI bioresilience push

Google DeepMind and Isomorphic Labs outlined a bioresilience program to curb AI misuse in biology while aiding outbreak response. The two organisations published an update on a joint initiative that began quietly and has now built out more than 15 partnerships with government bodies, biosecurity organisations, and research groups over the past 12 months. The
