In a high‑stakes courtroom showdown, Elon Musk’s legal team called UC Berkeley professor Stuart Russell to testify that artificial intelligence poses serious safety threats. Russell, a longtime AI researcher and signatory of a 2023 open letter urging a six‑month research pause, warned jurors and Judge Yvonne Gonzalez Rogers about cybersecurity vulnerabilities, misalignment risks, and the winner‑take‑all dynamics of a race toward artificial general intelligence. OpenAI’s attorneys pushed back, limiting his remarks and emphasizing that Russell was not evaluating the company’s internal safety policies. The testimony underscored a broader debate over profit‑driven AI development and the need for tighter regulation. Lire la suite

Two days before the high‑profile trial between Elon Musk and OpenAI began, the billionaire sent a series of texts to the AI lab’s president, Greg Brockman, urging a settlement and then threatening to make the executives “the most hated men in America.” A filing by OpenAI’s lawyers sought to admit the exchange as evidence, but a federal judge barred it, deeming the messages inadmissible. The ruling comes as Musk’s lawsuit seeks to dismantle OpenAI’s for‑profit structure, force public release of its technology, and strip Microsoft’s licensing deal, while OpenAI counters that the suit is a money grab.

A new Appfigures report shows that releasing image‑generation models has become the most effective way for AI mobile apps to attract users, delivering up to 6.5 times more downloads than traditional updates. OpenAI's GPT‑4o image model, Google’s Gemini Nano Banana, and Meta AI’s Vibes each sparked multi‑million install spikes, though only OpenAI turned the surge into significant consumer spending. The findings suggest visual capabilities now trump chat‑only upgrades in driving app growth, but the revenue impact remains uneven across providers. Lire la suite

Amazon Web Services, Microsoft and NVIDIA have signed agreements to provide the U.S. Defense Department with artificial‑intelligence tools for use on classified networks, the Pentagon announced. The deals, which also include startup Reflection AI, join similar contracts already in place with xAI, OpenAI and Google. Anthropic remains the only major U.S. AI firm without a Pentagon agreement, after a dispute with the administration over safeguards on its Claude chatbot. The rapid expansion of AI in the military has sparked public backlash, as evidenced by a sharp rise in ChatGPT uninstall rates following OpenAI’s own deal. Lire la suite

OpenAI announced that its upcoming GPT-5.5 model performed on par with the heavily promoted Mythos Preview in recent cybersecurity evaluations. CEO Sam Altman criticized the hype surrounding Mythos, calling it fear‑based marketing, while reiterating that the new model will initially be available only to a select group of critical cyber defenders. The company’s Trusted Access for Cyber pilot, launched in February, continues to serve as the gateway for researchers and enterprises to test frontier models under strict safeguards. Lire la suite

A Harvard-led trial comparing OpenAI's o1 reasoning model with human physicians in a Boston emergency department showed the AI correctly identified the exact or near‑exact diagnosis in 67% of cases, outpacing doctors who scored between 50% and 55%. When provided with more detailed patient information, the model's accuracy rose to 82% versus 70%‑79% for clinicians. Researchers caution the findings are not statistically significant and note the AI cannot assess visual cues or patient demeanor, but suggest the technology could serve as a rapid second opinion in emergency care.

The Department of Defense announced Friday that it has finalized classified‑use agreements with OpenAI, Google, Microsoft, Amazon, Nvidia, Elon Musk's xAI and the startup Reflection. The deals will let the Pentagon employ each company’s artificial‑intelligence tools in secure environments as it seeks to become an "AI‑first" fighting force. Anthropic, previously cleared for classified work, was left out after officials labeled its technology a supply‑chain risk and the company refused to relax red‑line restrictions on surveillance and autonomous weapons.

OpenAI president Greg Brockman told attendees at Sequoia Capital’s AI Ascent 2026 conference that artificial intelligence now writes roughly 80 percent of the firm’s code. Brockman qualified the number, noting it’s hard to pinpoint the exact share that isn’t AI‑generated. The remark adds to a growing chorus of AI lab leaders citing high productivity numbers, while independent studies question whether such claims translate into measurable gains for software engineering teams.

In a San Francisco federal courtroom, Judge Yvonne Gonzalez Rogers halted a heated exchange on artificial‑intelligence risk during the lawsuit between Elon Musk and OpenAI. The judge reminded Musk's attorney to stay on topic, steering the case back to allegations that OpenAI abandoned its nonprofit roots and became a profit‑driven enterprise. The ruling underscores that the trial will center on corporate governance, not existential threats, as the two tech titans clash over the future of the company behind ChatGPT. Lire la suite

OpenAI says its newly released ChatGPT Images 2.0 is seeing its strongest adoption in India, where the feature generated roughly 5 million app downloads during the launch week. Global activity rose only modestly, with daily active users and web traffic up about 1 percent. Emerging markets such as Pakistan, Vietnam and Indonesia posted sharper spikes, while U.S. downloads lagged behind. The upgrade, which handles more complex prompts and renders non‑Latin text more accurately, is being used largely for personal avatars, stylized portraits and creative fantasy visuals. Lire la suite

Anthropic has given investors just 48 hours to commit to its next fundraising round, which insiders say could bring in about $50 billion and close within two weeks. The company is aiming for a valuation near $900 billion—potentially higher—while gearing up for an IPO later this year. Early backers who invested in 2024 or earlier are sitting out, hoping to cash out when the stock debuts. The capital will fund Anthropic’s expanding compute infrastructure as its revenue run rate climbs toward $40 billion. Lire la suite

OpenAI announced it will roll out its GPT-5.5 Cyber suite to a select group of "critical cyber defenders" in the coming days, mirroring Anthropic's recent restriction of its Mythos tool. CEO Sam Altman posted on X that access will be granted through an application process that verifies users' credentials and intended use. The move aims to keep the powerful capabilities—penetration testing, vulnerability exploitation, and malware reverse engineering—from falling into the hands of malicious actors while the company consults with the U.S. government on broader availability.

OpenAI announced Thursday that it will roll out an optional Advanced Account Security tier for ChatGPT and Codex accounts. The new feature replaces passwords with physical security keys or passkeys, eliminates email and SMS recovery, and forces tighter sign‑in windows. Aimed at high‑risk users such as journalists, elected officials and researchers, the measure also blocks support staff from accessing recovery options, limiting attackers’ social‑engineering avenues. OpenAI partnered with Yubico to offer discounted YubiKey bundles and will require members of its Trusted Access for Cyber program to enable the tier by June 1. Lire la suite

OpenAI has detailed why its language models occasionally mention goblins, gremlins and other mythic creatures. The issue first surfaced with the GPT-5.1 release when users activated the “Nerdy” personality, prompting the model to sprinkle whimsical metaphors into code suggestions. Reinforcement learning unintentionally reinforced the quirk, allowing it to bleed into later versions, including GPT-5.5’s Codex tool, despite the company’s effort to suppress the behavior. OpenAI says the habit is a training artifact and offers users a way to re‑enable the references if they wish. Lire la suite

Microsoft announced on Monday that its long‑standing deal with OpenAI has been rewritten to let the AI startup sell its models on any cloud provider, including Amazon Web Services. The amendment extends Microsoft’s revenue‑share rights through 2032, removes an artificial‑general‑intelligence clause, and keeps Azure as OpenAI’s primary partner while opening the door for rivals to host the latest models. The shift follows months of tension over exclusivity and revenue terms, and it reshapes the financial and strategic stakes for both companies. Lire la suite
