🤖 Meta reenters the AI race with Muse Spark LINK

Meta has released Muse Spark, the first model from its new Superintelligence Labs division, marking the company's return to the frontier AI race after a quiet stretch.

Unlike previous Llama models, Muse Spark isn't open-weight and can't be run locally, though Meta says it has plans to open-source future versions of its AI models.

Independent testing by Artificial Analysis ranked Muse Spark in the top 5 on its Intelligence Index, but the model still trails competitors from OpenAI and Anthropic on agent-based tasks.

💰 Andy Jassy defends Amazon $200B spending spree LINK

Amazon CEO Andy Jassy wrote a shareholder letter defending the company's planned $200 billion in capital spending for 2026, arguing the investments are backed by real customer demand, not guesses.

Jassy disclosed that AWS' AI revenue has reached a $15 billion annual run rate, and Amazon's internal custom chips business is generating over $20 billion a year in value.

Amazon may sell its Trainium AI chip racks and robotics solutions to outside customers, following the company's pattern of building tools internally and then offering them as external services.

🚗 Tesla is developing a new smaller, cheaper EV LINK

Tesla is working on a new smaller, cheaper electric SUV that would be a distinct model from the existing Model 3 and Model Y, according to four people familiar with the matter.

The compact SUV would be about 14 feet long, weigh roughly 1.5 metric tons, use a smaller battery with shorter range, and cost substantially less than the $34,000 entry-level Model 3 in China.

The project is in early development with production planned for Tesla's Shanghai factory, though timing is unclear, and the company has a history of starting vehicles that end up delayed or canceled.

🚫 Meta removes ads for social media addiction litigation LINK

Meta started taking down advertisements from lawyers seeking clients who say they were harmed by social media as minors, blocking plaintiff recruitment tied to social media addiction litigation.

The move comes two weeks after Meta and YouTube were found negligent in a landmark California case, prompting law firms like Morgan & Morgan to run ads on Facebook and Instagram.

Meta cited its terms of service, saying it will not allow trial lawyers to profit from its platforms while simultaneously claiming they are harmful, and is actively defending against these lawsuits.

⚖️ Appeals court keeps Pentagon blacklisting of Anthropic in place LINK

A federal appeals court in Washington, D.C., denied Anthropic's request to temporarily block the Department of Defense's blacklisting of the AI company while its lawsuit challenging that decision moves forward.

The court said the equitable balance favors the government, noting Anthropic faces "relatively contained" financial harm while the DOD is securing AI technology during an active military conflict.

A separate federal judge in San Francisco last month granted Anthropic a preliminary injunction barring the Trump administration from enforcing a ban on the use of Claude.

⚡ OpenAI pauses Stargate UK over energy costs LINK

OpenAI has paused its Stargate data center project in the UK, pointing to high energy costs and regulatory burdens as the main reasons it cannot commit to long-term infrastructure investment.

The project, announced last September with Nvidia and Nscale, was tied to the UK's AI Growth Zone plan, which aimed to create 5,000 jobs and attract £30bn in private investment.

Stargate's $500bn US effort is already training AI systems at its Texas facility, with additional projects underway in the UAE and Norway, funded by OpenAI, Oracle, MGX, and SoftBank.
