A federal court in San Francisco has granted Amazon an injunction against AI startup Perplexity, barring it from using its AI browser agent Comet to make purchases on Amazon.
Amazon sued Perplexity in November, accusing the startup of fraud because Comet didn't disclose when it was shopping on behalf of a real person and ignored Amazon's demands to stop. The case raises a growing legal question: how should courts handle AI agents taking on complex tasks like online shopping?
Judge Maxine Chesney ruled that Amazon presented strong evidence that Perplexity was accessing users' password-protected accounts with their permission but without Amazon's authorization. Perplexity must also delete any collected Amazon data and has one week to appeal.
OpenAI is rolling out dynamic visual explanations for more than 70 math and science concepts in ChatGPT. Users can tweak variables in real time and see the effects on graphs and formulas instantly. For now, the topics are geared mainly toward high school and college students, covering things like binomial squares, exponential decay, Ohm's law, compound interest, and trigonometric identities.
According to OpenAI, the interactive explanations are available now to all logged-in users worldwide, regardless of their subscription plan. Over time, OpenAI plans to expand the learning modules to cover additional subjects.
German court says "It's AI" isn't enough to void copyright
A German regional court has ruled that song lyrics written by a human are still protected by copyright, even if the music was made with AI tools like SunoAI. Simply claiming a work is AI-generated isn’t enough to strip that protection, you need proof.
OpenAI plans to acquire Promptfoo, a security platform that helps companies catch and fix vulnerabilities in AI applications during development. If the deal goes through, the technology will be baked directly into OpenAI's Frontier enterprise platform, which companies use to build and deploy AI assistants.
The plan is to make automated security testing for prompt injections, jailbreaks, and data leaks a native part of Frontier. OpenAI also wants to beef up oversight, audit trails, and regulatory compliance tooling for enterprise AI deployments.
Microsoft has integrated Anthropic's Claude Cowork technology into Copilot. The new feature lets Microsoft 365 handle tasks more autonomously: users describe what they want done, and Cowork builds a plan that runs in the background, pulling from emails, meetings, files, and data across Outlook, Teams, and Excel. It's essentially Claude Cowork's approach, adapted for Microsoft's ecosystem. Use cases include calendar cleanup, meeting prep, company research, and product launch planning. When something's unclear, Cowork asks follow-up questions and waits for approval before making changes.
Cowork runs within Microsoft 365's existing security and compliance boundaries. It's currently in a limited research preview and is expected to become more widely available through the Frontier program by the end of March 2026.
The Department of War threatened Anthropic with two contradictory moves at once, the lawsuit states: invoke the Defense Production Act to force the company to hand over Claude, or ban it from the supply chain as a security risk. Anthropic argues the government can't claim a company is so essential it must be conscripted by law and so dangerous it should be blacklisted at the same time.
The lawsuit also challenges the legal basis for the government's actions. The statute cited, 10 U.S.C. § 3252, was written for cases where a foreign adversary might sabotage or subvert an information system. The government's own definition of "foreign adversary" covers China, Russia, Iran, North Korea, Cuba, and Venezuela.
A new omni model from OpenAI? Employee posts and a leaked audio project called “BiDi” suggest the company is working on its next big multimodal upgrade.
Anthropic's Claude Opus 4.6 saw through an AI test, cracked the encryption, and grabbed the answers itself
Anthropic’s Claude Opus 4.6 independently figured out it was being tested during a benchmark, identified the specific test, and cracked its encrypted answer key. According to Anthropic, this is the first documented case of its kind.
