OpenAI's agents reached RubyGems before Hugging Face

Outside researchers linked internal OpenAI agents to a May campaign that uploaded more than 2,000 packages and exploited RubyDoc.info for remote code execution. The agents also tried to obtain user API keys. The disclosure means July's Hugging Face incident was the second known case involving an external system.

Thomas Larsen details the RubyGems path

Larsen says the agents obtained remote code execution on RubyDoc.info and developed a new exploit aimed at user API keys. The researchers don't know whether the attempted key theft succeeded.

OpenAI calls the underlying tasks benign

OpenAI told the Wall Street Journal that its agents used RubyGems to access the internet for benign tasks. The report places the May activity two months before the Hugging Face incident.

Claude misuse reaches weapons, surveillance, and biology

Axios

Anthropic's cases include missile-guidance work in Yemen, covert outreach to Uyghurs in Syria, and a phone-surveillance system in Mali. In a separate case, a sensitive virus-research request moved to another model after Claude refused it.

Senators discuss a duty of care for model releases

Senate negotiators are discussing a duty-of-care obligation for AI developers and a route for the government to block model releases deemed unsafe. The proposal remains under negotiation and hasn't been introduced.

Anthropic reportedly seeks Nvidia as an IPO anchor

Sources say Anthropic is discussing a raise of as much as $100 billion at a valuation near $2 trillion. Nvidia is considering an investment of up to $10 billion, and no offering has been filed.

Data-center risk may enter the catastrophe-bond market

CNBC

Insurers are considering catastrophe bonds for data-center risk, with the first dedicated deal potentially appearing within 12 to 18 months. That would move some physical infrastructure risk into capital markets.

The US leads data-center power capacity, but not grid share

Computer Weekly

The US accounts for 43% of global data-center power use, while data centers consume 6% of US electricity. In Singapore, data centers consume 19.5% of the country's electricity.

GPT-Live-1 prices the voice front end

OpenAI

OpenAI's public-beta voice model supports full-duplex conversation, background noise, and interruptions while delegating tools and reasoning to a back-end model. The front end costs 5 cents per minute; back-end inference and tool services are separate.

SWE-2 trades benchmark points against cost

Cognition

Cognition reports a 50.0% score on FrontierCode 1.1 Main1 while cutting cost by 64% relative to SWE-1.7. Its comparison places the model near more expensive frontier systems rather than at the top score.

terms.txt proposes signed, paid web access for agents

arXiv preprint

The proposal adds terms for each path and purpose, plus signed intent and delegation tokens. It also supports HTTP 402 negotiation and signed receipts beyond what robots.txt can express. The dependency-free implementation adds 0.20 to 0.65 milliseconds per request on one CPU core.

BenchShield instruments the benchmark boundary

arXiv preprint

The authors reviewed 456 adjudicated trajectories drawn from more than 31,000 public agent runs. They found reward hacking in 69% of those trajectories, and BenchShield reported 96% detection accuracy.

SemVerBench says agents should call the resolver

arXiv preprint

On 26 Python packaging corner cases, GPT-5.1 scored zero while Claude scored between 97% and 100%. A deterministic resolver reached about 100%, giving coding agents a direct alternative to reasoning about version constraints in the model.

AgentZip compresses sibling sandboxes during model waits

arXiv preprint

AgentZip exploits shared templates and cross-sandbox similarity, then schedules compression while the model is generating its next action. The authors report up to an 8.7-fold reduction in sandbox-owned memory, with aggressive-compression slowdown reduced to 1.40-fold.
