GIVE ANY AI AGENT ACCESS TO GOOGLE SEARCH WITH SERPAPI (SPONSOR) [4]
Agents are smarter when they can search the web. But scraping Google
gets expensive when you're burning extra tokens to parse messy SERPs
into readable text.
SerpApi [4] is the web search API [4] that gives you exactly what you
need, out of the box:
👉 SCRAPE GOOGLE AND OTHER SEARCH ENGINES
👉 INTEGRATE WITH A SIMPLE GET REQUEST that any agent can make; get
RESULTS IN .MD OR .JSON that any agent can read.
👉 Used by NVIDIA, ADOBE, SHOPIFY, and even the United Nations.

ANTHROPIC SAYS CLAUDE DRIVES 26% OF ITS RESEARCH AND DEVELOPMENT (3
MINUTE READ) [5]
Anthropic claims that its Claude chatbot drives more than a quarter
of its research and development work. There are over 30,000 agents
doing research and engineering work at Anthropic at any one time. Its
staffers collaborate with the chatbot for about 90% of their work. The
company is trying to create a framework to track agents and monitor
the amount of work they do.
HUAWEI'S PLAN TO BECOME CHINA'S NVIDIA (3 MINUTE READ) [6]
Huawei plans to release two new AI chips next year. The company has
now shipped more than 1,000 of its AI-computing systems to over 370
customers. China's AI chip market is projected to grow to $67 billion
by 2030. Huawei's chip-making technology still trails Nvidia's, but
the company is developing workarounds and new designs to squeeze in
more computing power while using less advanced equipment.

HELIX 2.5: ZERO-SHOT 30-HOME GENERALIZATION (14 MINUTE READ) [7]
Helix 2.5 is an advanced neural network pretrained on Index, Figure's global-scale dataset of human behavior. It can tidy living rooms, fold
towels, and make beds in homes it has never seen. The model is the
first evidence that whole-body intelligence can be learned from human experience and transferred to new scenarios. Index is now generating
roughly 35 minutes of new human experience every second - if Helix 2.5
is any guide, more data and compute should translate directly into
more of the physical world learned before a robot ever enters a new
home.
HOW SPACEX STREAMLINED THE RAPTOR ENGINE (17 MINUTE READ) [8]
The differences between the versions of the Raptor rocket engine are
stark. Many people initially didn't believe SpaceX when the company
released a picture of the three generations of the design. The
streamlining of the design also brought meaningful gains in
performance - the Raptor 3 provides about 35% more thrust than the
Raptor 1. This article looks at what specifically SpaceX changed that
allowed it to take the Raptor from a tangle of wires and pipes into
the svelte, streamlined engine it is today.

HACKING OPENAI (11 MINUTE READ) [10]
Researchers chained two critical vulnerabilities to compromise
multiple OpenAI employees' ChatGPT accounts in July. The accounts
could access internal OpenAI repositories and potentially many other connectors. They used one employee's Codex to open a PR in OpenAI's
internal monorepo. This post provides a full timeline of the
disclosure process and details about how the vulnerabilities were
discovered.
WEBKIT FEATURES FOR SAFARI 27.0 (142 MINUTE READ) [11]
The release notes on the WebKit features for Safari 27.0 are the
longest yet, detailing 83 features, including Safari MCP. Safari MCP
makes working with coding agents dramatically easier. It gives users'
agent of choice control over the browser window so it can see how code
renders. The MCP provides access to the DOM, network requests,
screenshots, and console output, allowing agents to do more with less
effort from users.

THE STARTUP THAT BUILT OPENAI'S BIGGEST DATA CENTER IS NOW MAKING
TINY ONES (6 MINUTE READ) [12]
Crusoe built one of the world's biggest AI supercomputers in Abilene,
Texas. The company is now investing heavily in smaller data centers.
It is manufacturing them in factories, loading them onto flatbed
trucks, and deploying them wherever it can find available power. The
company believes this is a faster and cheaper method than solely
relying on large construction projects. Giant clusters with hundreds
of thousands of chips are useful for training, but inference can be
done with considerably smaller amounts of chips.
INSIDE THE WHITE HOUSE TUSSLE TO SWAY TRUMP ON AI (11 MINUTE READ)
[13]
Anthropic's Mythos model sparked a shift within the White House as
officials started realizing that AI can be used to launch cyberattacks
and pose national-security threats. White House officials and AI
executives are working on regulatory efforts, but when they disagree,
the executives have gone directly to Trump. Trump has remained
resolute that the nation needs to accelerate AI development and
continue to build the data centers that are powering the AI boom.
