Florida Attorney General James Uthmeier has launched a criminal investigation into OpenAI and its ChatGPT chatbot after a review of chat logs linked to the April 17, 2025 shooting at Florida State University in Tallahassee. Prosecutors say messages show the accused gunman, Phoenix Ikner, queried ChatGPT on weapon choice, matching ammunition, lethality at short range, and the busiest time and location at the student union where the attack occurred. Uthmeier said his team concluded the chatbot offered “significant advice” and issued subpoenas to OpenAI seeking policies and internal training materials on handling users who threaten harm, and on cooperation with law enforcement, covering March 2024 through April 2026. The criminal probe runs alongside a civil inquiry; family members of victims have signalled intent to sue. OpenAI says it shared account information with authorities, disputes responsibility for the crimes and maintains ChatGPT did not encourage illegal acts, providing only factual material available publicly. The case follows other lawsuits and scrutiny of chatbots after mass violence and suicides allegedly involving AI tools.

Sony AI’s autonomous robot ‘Ace’ has reached expert-level performance in competitive table tennis, according to a study published in Nature on April 22, 2026. Built around an eight-jointed robotic arm and a high-speed sensing suite (multiple high-frame-rate cameras and event-based vision systems), Ace uses model-free deep reinforcement learning trained in simulation to perceive spin, predict trajectories and execute shots with millisecond latency. In April 2025 it beat three of five elite players under International Table Tennis Federation rules; after further development it recorded victories over professional opponents in December 2025 and March 2026, including a win against a top-25 player. Matches were officiated by licensed umpires on regulation courts. Researchers say Ace’s strengths include superior spin estimation, rapid reaction time and unpredictability; limitations include reliance on an external camera network, a non-humanoid mounting platform and limited ability to read human body language. Sony AI and outside experts highlight potential applications of the underlying perception and control technologies in manufacturing, service robotics, sports training and other fast, safety-critical environments, while also noting ethical and security considerations as capabilities mature.

A UK Competition Appeal Tribunal has certified a collective opt-out lawsuit against Microsoft alleging it overcharged nearly 60,000 British businesses for Windows Server licences when run on rival cloud platforms. The claim, brought by competition lawyer Dr Maria Luisa Stasi, seeks about £2.1 billion (roughly $2.8 billion) and contends Microsoft set higher wholesale prices for Windows Server on Amazon Web Services, Google Cloud and Alibaba Cloud than for equivalent usage on its own Azure service, making competitors comparatively more expensive. The tribunal dismissed Microsoft’s challenge that the claim lacked a workable method for calculating losses and concluded the action “comfortably crosses” the threshold for a real prospect of success. A Collective Proceedings Order will be published with opt-out details and timelines; Microsoft said it would appeal and denied any wrongdoing. The ruling comes amid growing regulatory scrutiny of Microsoft’s cloud and licensing practices by the UK’s Competition and Markets Authority and probes in Europe, the US and elsewhere. The decision keeps a major test of cloud licensing and competitive practices on track for trial and could lead to damages, settlements or changes to licensing terms if claimants prevail.

Meta is installing tracking software called the Model Capability Initiative (MCI) on U.S.-based employees’ work computers to capture mouse movements, clicks, keystrokes and occasional screenshots for use as AI training data, according to internal memos seen by Reuters and reporting by multiple outlets. The tool will run only on a pre-approved list of work apps and websites and is described internally as part of an “Agent Transformation Accelerator” effort to build agents that can perform routine computer tasks. Meta spokespeople said safeguards will protect sensitive content and that data will not be used for performance reviews. The rollout has provoked internal backlash — employees report no opt-out on company laptops — and comes amid major corporate AI investments, a Superintelligence Labs reorganisation and plans to cut about 10% of the workforce starting in May. Legal experts note U.S. federal law places few limits on workplace monitoring, while EU rules would likely bar similar measures there.

Meta Platforms said on April 21-22, 2026 it has begun construction of a data centre in Tulsa, Oklahoma, a project valued at more than $1 billion located at Fair Oaks Innovation Park. The campus will span more than 2 million square feet, be built by Fortis Construction, and will be Meta’s 28th U.S. facility and 32nd worldwide. The company expects peak construction to create over 1,000 jobs and about 100 permanent operational roles, and has pledged to pay site water and wastewater costs and more than $25 million for local infrastructure upgrades. Separately, Meta disclosed a ‘Model Capability Initiative’ that deploys tracking software on U.S. employees’ computers to record mouse movements, clicks, keystrokes and intermittent screenshots to train AI models; Meta says the data won’t be used for performance reviews. The announcements come as Meta accelerates AI investment amid reports of planned layoffs and rising environmental and privacy scrutiny.

Paramount Skydance has rolled out a redesigned Paramount+ app for Apple iPhone users that places a vertical, scrollable feed of short videos front and center, Reuters and other outlets reported in April 2026. The feed features sports highlights, CBS News segments, UFC clips and movie trailers aimed at driving frequent daily visits and higher ad impressions. The change is part of a broader technology consolidation after the Skydance merger, with Paramount working to unify Paramount+, Pluto TV and other assets into a single backend stack targeted for mid-2026. Executives hope the short-form format will enable new ad formats, real-time features during live sports and partnerships with influencers; Paramount declined to comment. Industry data cited in reporting show Paramount accounted for about 2% of global streaming app usage in Q1 2026, while YouTube’s user base dwarfs Paramount+ by roughly 59-to-1 per app-measurement firms. The redesign comes as streaming rivals likewise experiment with social-style features and as Paramount outlines advertiser-facing changes tied to its wider overhaul and planned combinations with other studio assets.
