Sequoia Capital announced a $7 billion raise for a fresh fund aimed at late‑stage investments in artificial‑intelligence companies across the United States and Europe. The capital, nearly double the size of the firm’s 2022 vehicle, underpins Sequoia’s “expansion strategy” under its newly appointed co‑stewards Alfred Lin and Pat Grady. Backing already includes OpenAI, Anthropic and a slate of emerging AI startups, positioning the Silicon Valley stalwart to ride the rapid scaling of AI‑driven businesses. Lire la suite

On April 14, 2026, OpenAI announced GPT-5.4-Cyber, a model built for digital defenders, and detailed a three‑pillar strategy to safeguard generative AI against cyber threats. The rollout follows Anthropic’s private release of Claude Mythos Preview, which the company warned could be weaponized by hackers. OpenAI says its existing safeguards already reduce risk sufficiently and outlines new controls—including a "know your customer" access system, iterative deployment, and expanded security investments—to protect current and future AI capabilities.

OpenAI announced a major upgrade to its Agents SDK, introducing sandboxing capabilities and an in-distribution harness for frontier models. The new features let businesses run AI agents in isolated environments and test them with advanced models while keeping systems secure. Initially available in Python, with TypeScript support slated for later, the tools aim to help enterprises build longer‑horizon, multi‑step agents without risking unintended actions. OpenAI says the enhancements will be offered through its standard API pricing. Lire la suite

Venture capital firms have been circling Anthropic with offers that could value the AI startup at more than $800 billion, but the company has so far declined to engage. The offers come after Anthropic raised $30 billion in a February round that set its valuation at $380 billion, and they rival OpenAI’s recent $852 billion post‑money valuation. With $50 billion earmarked for its own data‑center build‑out, $30 billion committed to Microsoft’s cloud, and billions spent on AWS, Anthropic appears intent on funding growth internally rather than seeking fresh equity.

Anthropic has formally rejected Illinois Senate Bill 3444, a proposal that would shield AI developers from liability for large‑scale harms such as mass casualties or billion‑dollar property losses. The bill, championed by state Senator Bill Cunningham and supported by OpenAI, would exempt labs that publish safety frameworks from responsibility if their models are misused. Anthropic’s U.S. state‑government liaison, Cesar Fernandez, called the measure a “get‑out‑of‑jail‑free card,” urging instead for transparency paired with real accountability. Illinois officials, including Governor JB Pritzker’s office, have signaled they will monitor the legislation but are wary of granting blanket immunity. Lire la suite
