OpenAI announced a $110 billion funding round at a $730 billion pre-money valuation backed by Amazon, Nvidia, and SoftBank to expand compute, distribution, and enterprise infrastructure. The company now supports 900 million weekly active users, 50 million consumer subscribers, 9 million paying business users, and 1.6 million weekly Codex developers, extending AI use deep into workflows across business functions. This capital and strategic cloud partnerships aim to shift frontier AI from research to global production scale with broader enterprise and developer adoption.

Google accidentally revealed a new Gemini feature, "Goal Scheduled Actions," that allows AI to autonomously adjust tasks toward defined objectives. This contrasts with existing scheduled actions that repeat fixed prompts. The feature aligns with Google's LearnLM initiative, suggesting applications in education, where structured AI guidance could aid skill development.

Anthropic was recently declared a supply chain risk due to its refusal to allow the Department of War to use its technology for mass surveillance and autonomous weapons. A few hours later, the Department of War announced a partnership with OpenAI. While OpenAI and the Department of War have tried to assure the public that they won't use AI for mass surveillance and autonomous weaponry, there are wide loopholes in current laws against their use. The Department of War is also able to change many of the rules that currently exist at any time.

<strong>Why XML Tags Are so Fundamental to Claude (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Structuring prompts with XML can be a transformative experience in Claude. The AI's framework specifically incorporates XML tags as key elements. The repurposing of XML technology may be a core aspect of what makes Claude distinctive. It gives Claude the ability to distinguish between the transition from first-order to second-order expressions, which is a mechanism fundamentally required for information transfer between any two entities. Claude's awareness of the concept of delimiters is crucial to every processing and communication of information, and it is this capacity that makes Claude so effective at interpreting layered meaning.

<strong>90% of Expert Work Can't Be Verified by Today's AI Training Methods (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Around 90% of expert work across healthcare, legal, finance, and engineering relies on subjective judgment, making it incompatible with current RLVR-style verification. To force verifiability, teams over-specify tasks and rubrics, turning real expert reasoning into shallow instruction-following and corrupting the training signal. Verification, not data scale, is the core bottleneck, and the winners will be those who can evaluate judgment-heavy, non-deterministic work without distorting it.

<strong>The Third Era of AI Software Development (3 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cursor described a shift toward autonomous coding agents that operate over longer time horizons with minimal supervision, marking a “third era” of AI-assisted development. The company reported that over one-third of its merged pull requests were generated by cloud-based agents and outlined a future where developers manage fleets of agents rather than write code directly.

MCP is already dying. Major projects like OpenClaw and Pi don't support it for good reason. LLMs are really good at figuring out things on their own. All they really need is a command-line interface and some docs. CLIs are much more practical for both humans and agents. The tools already exist and are well-documented, and both humans and agents understand how to use them.

<strong>Andrew Ng Says AGI Is Decades Away—and the Real AI Bubble Risk Is in the Training Layer (2 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Andrew Ng, founder of DeepLearning.AI and Coursera, executive chairman of Landing AI, and founding lead of the Google Brain team, says that AI capable of performing the full breadth of human intellectual tasks remains decades away. He recently appeared in an interview where he discussed enterprise adoption of agentic AI, whether AI is in a bubble, the AI infrastructure build-outs, geopolitical fragmentation and its effects on global AI strategy, and more. This post contains a transcript of that interview.

<strong>When AI Labs Become Defense Contractors (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Government contacts offer predictable, multi-year, politically protected revenue streams that don't churn when a competitor releases a better model. Any lab serious about classified work has to build an organizational structure that meets government operational security requirements, and the lab that builds that structure first has a moat that no competitor can cross quickly. The defense budget is the largest single purchaser of advanced technology on the planet, and it's growing. Its multi-year contract cycles reward incumbents, and it's willing to use blunt regulatory tools against companies that don't cooperate.
