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 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.

Caitlin Kalinowski was not the head of all robotics at OpenAI. She was responsible for hardware and operational topics within the Robotics Division. She was also not a researcher and did not lead Robotics Engineering. The Robotics Division is led by Aditya Ramesh, while the Consumer Hardware Division is headed by Peter Welinder.

OpenAI's hardware and robotics chief Caitlin Kalinowski resigned over the company's military collaboration,announcing her decision on LinkedIn and X. She says surveillance without judicial oversight and lethal autonomy without human sign-off "deserved more deliberation than they got." Kalinowski joined from Meta in November 2024, where she built the Orion AR headset.

OpenAI is launching a new support program for open-source developers. Core maintainers of public software projects can apply for six months of free access to ChatGPT Pro with Codex, API credits, and Codex Security. Codex Security, a new AI tool for code security checks, will be reviewed on a case-by-case basis and only granted selectively due to the capabilities of GPT-5.4, according to OpenAI.
Developers who prefer other programming tools like OpenCode, Cline, or OpenClaw can also apply. Projects that don't meet all the criteria but play an important role in the broader software ecosystem are also welcome to apply. The program builds on OpenAI's existing Codex Open Source Fund, which the company has backed with one million dollars.
OpenAI and Oracle have decided not to expand their data center site in Abilene, Texas, beyond the planned 1.2 gigawatts. Oracle has leased eight buildings at the location for OpenAI, designed to house around 400,000 Nvidia Blackwell chips, but only two have been completed so far.
Oracle had pushed to get OpenAI into six more buildings, but both sides passed because the additional power supply wouldn't be available for at least a year. Instead of expanding the current Blackwell generation, OpenAI plans to buy Nvidia's next-generation Vera Rubin chips for a different data center. According to Bloomberg, Nvidia is now trying to get Meta to fill the vacant space, though those talks are still in the early stages.
OpenAI's compute manager Sachin Katti described the Stargate site as already one of the largest AI data center campuses in the country. "We considered expanding it further, but ultimately chose to put that additional capacity in other locations," Katti writes, adding that OpenAI is currently developing more than half a dozen sites across several US states.
OpenAI launches "Codex Security," an AI-powered security agent built to find vulnerabilities in software projects. The tool, formerly known as "Aardvark," is now available as a research preview for ChatGPT Enterprise, Business, and Edu customers, free for the first month. Codex Security analyzes code repositories, builds a project-specific threat model, and tests any vulnerabilities it finds in isolated test environments, OpenAI says.
During the beta phase, OpenAI says the system cut false positives by more than 50 percent and reduced redundant alerts by 84 percent in one case. Over the past 30 days, Codex Security scanned more than 1.2 million commits and flagged 792 critical vulnerabilities.
Anyone worried about an AI bubble now has more reason for concern: Softbank is looking to borrow up to $40 billion, primarily to finance its stake in OpenAI, Bloomberg reports. If the deal goes through, it would be the largest pure dollar borrowing in the Japanese conglomerate's history. The bridge loan would run for about twelve months, with four banks—including JPMorgan Chase—underwriting it. Negotiations are still ongoing.
SoftBank founder Masayoshi Son is making a massive bet on artificial intelligence. Beyond the $30 billion earmarked for OpenAI, the company has already poured over $30 billion into the startup and held roughly eleven percent of its shares as of late December. To fund these investments, SoftBank sold off Nvidia shares, among other assets.
OpenAI is launching "ChatGPT for Excel," a beta add-in that lets users create, edit, and analyze spreadsheets through natural language. The tool runs on the new GPT-5.4 model, which OpenAI says is specifically optimized for financial tasks like modeling, scenario analysis, and data evaluation.
