Amazon’s built-in price tracking feature now allows you to see how much a product’s price has changed over the past year. To use the feature, open the Amazon app and select the “Price history” button next to the item’s price, or ask Amazon’s AI assistant Rufus.

The expansion comes just weeks ahead of Amazon’s annual Prime Day event, which California Attorney General mentioned in his “price fixing” lawsuit against the retail giant. In the lawsuit, Bonta accuses Amazon of pushing other companies to raise the price of their products at other retailers in the days leading up to its annual deals event. Bonta also claims Amazon “bullied vendors to hike up the price of their products sold at other shops, or secured the removal of these products altogether.”

Amazon’s expanded price tracking tool is now available in the US, UK, and India. Though the company initially rolled out the built-in tracker in 2024, you could only view an item’s price across 30 and 90 days until now. You can also use third-party tools, like CamelCamelCamel and Keepa, to check product price history on the site.

The unions backing professional NBA, NFL, MLB, NHL, and MLS players are calling on the Commodity Futures Trading Commission (CFTC) to ban prediction market platforms from allowing users to bet on a player’s underperformance or injury, Sports Business Journal reports. In their letter, the unions cite the need for “appropriate regulations” to protect athletes and their families from “abusive and harassing behavior.”

The unions wrote the letter in response to the CFTC’s request for comment on the regulation of prediction markets, such as those operated by Kalshi and Polymarket. In addition to asking for a ban on “under” bets, the unions also want the CFTC to prevent people from betting on whether certain words or phrases are spoken during a broadcast, like “concussion” — which they describe as “another way of betting on a negative outcome.“

In 2024, Jontay Porter, a former Toronto Raptors center, pleaded guilty to conspiracy to commit wire fraud over a betting scandal that involved “limiting his own participation in one or more games for betting purposes,” according to the NBA. The US Department of Justice also charged several current and former NBA players last year with “using private locker room and medical information to enrich themselves.”

The sports unions write that the CFTC should ban the “unauthorized use” of information related to a player’s injury, illness, performance metrics, or other health data as well. Separately, the NBA asked that the CFTC limit prediction market betting to people over 21. Kalshi and Polymarket currently allow users aged 18 or older to join.

As prediction markets rise in popularity, the CFTC has fought back against states’ attempts to regulate the platforms. So far, the CFTC has filed lawsuits against Arizona, Connecticut, Illinois, New York, and Wisconsin, which accuse the states of violating the CFTC’s “regulatory authority” over prediction betting markets by trying to impose rules on them.

OpenAI is opening up about its goblin problem. After a report from Wired revealed instructions to OpenAI’s coding model to “never talk about goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures,” the AI startup published an explanation on its website, calling references to the creatures a “strange habit” its models developed as a result of their training.

As outlined in the blog post, OpenAI began noticing metaphors referencing goblins and other creatures starting with its GPT-5.1 model — specifically when using the “Nerdy” personality option. OpenAI says the problem continued to worsen with subsequent model releases, until it found that its reinforcement training rewarded the quirky metaphors with the Nerdy personality, which newer models were training on.

The rewards were applied only in the Nerdy condition, but reinforcement learning does not guarantee that learned behaviors stay neatly scoped to the condition that produced them. Once a style tic is rewarded, later training can spread or reinforce it elsewhere, especially if those outputs are reused in supervised fine-tuning or preference data.

Though references to goblins and gremlins dropped off after OpenAI discontinued the Nerdy personality in March, they didn’t disappear completely with GPT-5.5 inside its Codex coding tool, as OpenAI started training the model before finding the “root cause.” The company had to give Codex very specific instructions not to talk about the mythological creatures as a result. But if you’d prefer to have your AI code with some goblin sprinkled in, OpenAI has shared a way to reverse its instructions.

Microsoft’s Xbox hardware revenue continues to tumble, with the company revealing a 33 percent decline as part of its earnings report released on Wednesday. Even though the rest of Microsoft’s consumer-focused division took a dip, the company’s cloud and productivity businesses continue to soar, driving the company toward $82.9 billion in revenue.

Along with declining Xbox hardware revenue, Microsoft reported a 5 percent drop in Xbox content and services as well. Microsoft has seen a significant amount of executive turnover over the past few months, with the retirement of Xbox chief CEO Phil Spencer and the departure of former Xbox president Sarah Bond. This has left former Microsoft CoreAI product head Asha Sharma in charge of the gaming giant, which has struggled with its identity in recent years. Already, Sharma has lowered the price of Xbox Game Pass and has taken steps to rebuild Xbox’s identity.

Microsoft CEO Satya Nadella reflected on these changes during an earnings call, saying it’s part of efforts to “win back fans” across its brands, including Xbox. “The team is recommitting to our core fans and players and shaping the future of play,” Nadella said. “Last week’s Game Pass changes are one example of how we are staying responsive to customer feedback.”

Nadella also cited changes to Windows, which have “brought performance improvements for lower memory devices, streamlined the Windows Update experience, and brought back focus to core features and fundamentals.” The company recently started letting customers pause Windows Updates indefinitely, and also got rid of “unnecessary” Copilot buttons across Windows 11 apps.

In addition to an executive shuffle, Microsoft has only pushed further into AI in recent months, with the company reporting $54.5 billion in revenue from its cloud business, marking a 29 percent year-over-year increase. “We are focused on delivering cloud and AI infrastructure and solutions that empower every business to eval-max their outcomes in the agentic computing era,” Nadella said in the press release. “Our AI business surpassed an annual revenue run rate of $37 billion, up 123% year-over-year.” Revenue earned by Azure and other cloud services went up 40 percent.

Microsoft 365 Copilot saw growth as well, with paid seats jumping from 15 million in the previous quarter to 20 million. Microsoft has continued building out its productivity suite with new AI features, including the launch of “vibe working” features across Excel, Word, and PowerPoint. The company says Microsoft 365 consumer cloud revenue increased 33 percent during this quarter, while its commercial segment increased 19 percent.

Meanwhile, revenue earned by Microsoft’s Windows OEM and devices business decreased by 2 percent as it grapples with a global memory shortage that has led it to hike the prices of its Surface devices. The launch of new Surface Pro and Surface Laptop models in the coming months could help reverse the decline.

Update, April 29th: Added comments from Nadella.
