The Walt Disney Company sent a cease and desist letter to Character.AI last week, warning the artificial intelligence startup to stop using copyrighted characters without authorization, a Disney spokesperson confirmed to CNBC on Tuesday.

A spokesperson for Character.AI said it removed the characters mentioned in the letter, and that “it’s always up to rightsholders to decide how people may interact with their IP.”

The spokesperson acknowledged that while some characters on its platform are completely original creations, others are “inspired by existing characters that people love.”

“We want to partner with the industry and rightsholders to empower them to bring their characters to our platform,” the Character.AI spokesperson told CNBC. “Our goal is to give IP owners the tools to create controlled, engaging and revenue-generating experiences from deep fandom for their characters and stories, expanding their reach using our new, interactive format.”

The letter serves as the latest example of how media companies like Disney are working to protect their intellectual property during the AI boom.

Disney is already involved in an ongoing lawsuit against AI image creator Midjourney, alleging that the company improperly used and distributed AI-generated characters from movies like “Cars,” “Toy Story,” “Shrek,” “The Avengers” and others. 

Axios first reported the cease and desist letter.

Character.AI allows users to create and interact with character-based chatbots. Google inked a $2.7 billion licensing deal with Character.AI and hired its founders in 2024, and the startup became embroiled in a wrongful death lawsuit that same year.

The family of Sewell Setzer III, a 14-year-old boy in Florida, alleged he committed suicide after he became addicted to talking with a number of AI chatbots on the app. One of the chatbots was named Daenerys Targaryen, or Dany, who is a character in the show “Game of Thrones,” according to the lawsuit.

Character.AI is not the only AI company that’s faced scrutiny over its approach to IP.

Earlier this month, a federal judge preliminarily approved Anthropic’s offer to pay $1.5 billion to settle a class action lawsuit with a group of authors, who claimed that the company had illegally downloaded their books and others from pirated databases.

Amazon on Tuesday unveiled four new smart speakers and voice-activated displays that are revamped with Alexa+, its personal assistant that’s powered by generative artificial intelligence.

The company debuted the Echo Dot Max, a revamped version of its compact smart speaker, which costs $99.99. Amazon also unveiled a new Echo Show 8 and Echo Show 11, priced at $179.99 and $219.99, respectively.

There’s also a new version of the Echo Studio, a larger, higher-end model with a more powerful speaker, priced at $219.99.

All the devices are available for preorder on Tuesday, and users will get Alexa+ early access “out of the box,” Amazon said. The Echo Dot Max and Echo Studio ship Oct. 29, while the Echo Show 8 and Echo Show 11 ship Nov. 12.

The devices were launched at Amazon’s fall hardware bonanza, held in New York. They’re the first batch of revamped products under the leadership of Panos Panay, a former Microsoft hardware leader who joined Amazon in 2023.

It’s also the first set of Amazon hardware to integrate the company’s long-awaited Alexa+, which debuted in February and has slowly rolled out in early access for some users.

“These are the most powerful Echo devices we have ever created,” Panay said on stage at the event. “Custom silicon, advanced sensors, our best microphones and sound, noise cancellation, understanding the user, faster than anything we’ve ever delivered before. They’re also beautifully designed to fade into the background.”

Alongside a revamped look, Amazon added new AZ3 and AZ3 Pro chips for edge processing to the devices, which are faster, more powerful and have “AI built right in,” said Daniel Rausch, the head of Amazon’s Alexa and Echo businesses.

The devices also feature a so-called Omnisense platform that gives Alexa “better contextual awareness,” Rausch said. It allows the Echo Show to be able to recognize users and serve up personalized insights, like an analysis of how they slept last night or alert users if they left their front door unlocked after midnight.

Amazon faces growing pressure to update its hardware and software for the generative AI age following the success of rivals such as OpenAI’s ChatGPT and Google’s Gemini. Meta also has its Ray-Ban Meta glasses, which use its Llama large language model to answer spoken questions from the user.

Amazon is also looking beyond Alexa or Echo smart speakers for opportunities in device growth.

The company in July confirmed it’s acquiring AI wearables startup Bee, which makes a wristband that can record and transcribe conversations.

Nvidia shares reached a fresh record on Tuesday, climbing almost 3% and lifting the chipmaker’s market cap past $4.5 trillion.

The stock is now up about 39% for the year, and continues to attract investors as Nvidia steps up its pace of deal-making, cementing its position at the center of the artificial intelligence boom.

OpenAI said last week that Nvidia would take an equity stake worth up to $100 billion in the AI startup, and would build hundreds of billions of dollars worth of data centers filled with Nvidia graphics processing units. OpenAI then announced five massive new data centers with Oracle that are expected to be filled with hundreds of thousands of GPUs. The whole “Stargate” project will cost $500 billion, the companies said.

Nvidia CEO Jensen Huang says Nvidia’s products comprise about 70% of the spending on a new AI data center.

Analysts at Citi on Tuesday raised their price target on Nvidia from $200 to $210, citing an increased forecast for AI infrastructure spending after the OpenAI announcements.

“We believe OpenAI came to Nvidia asking for help as Nvidia has a very compelling product, and as the number of users and compute being consumed per user basis is growing,” Citi analyst Atif Malik wrote in the note.

OpenAI is far from alone, as Meta, Google and others are also dramatically ramping up their infrastructure spending.

CoreWeave, a cloud provider that includes Nvidia as a large shareholder, said Tuesday it had reached a deal to supply Meta with $14.2 billion in AI infrastructure services.

Nvidia’s stock is outperforming all of its megacap peers so far this year except for chipmaker Broadcom, which is up about 40%, similarly boosted by OpenAI.
