GOOGLE TESTS JULES V2 AGENT CAPABLE OF TAKING BIGGER TASKS

Google is developing the Jules V2 ("Jitro") coding agent, designed to autonomously manage high-level development goals rather than specific tasks. Launching via waitlist, it aims to redefine AI software development by shifting focus from task-based commands to KPI-driven outcomes. The approach might benefit teams handling large codebases, but it faces challenges of unpredictable changes and trust issues.

ANTHROPIC EXPANDS PARTNERSHIP WITH GOOGLE AND BROADCOM FOR MULTIPLE GIGAWATTS OF NEXT-GENERATION COMPUTE

Anthropic has signed an agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity expected to come online starting in 2027. The capacity is necessary to serve the exponential growth in Anthropic's customer base. It will also enable Claude to define the frontier of AI development. The vast majority of the new compute will be sited in the US.

SOME OF META'S NEW AI MODELS WILL EVENTUALLY BE OPEN-SOURCE

Meta is close to releasing its new AI models. Some of the models will eventually be released with an open-source license. Meta plans to focus on consumers rather than the enterprise market. It previously embraced open-source AI with its Llama models, and CEO Mark Zuckerberg has written a manifesto declaring open-source AI as the past for ared. The company will be pursuing a hybrid strategy of proprietary and open-source models going forward.

AIS CAN NOW OFTEN DO MASSIVE EASY-TO-VERIFY SWE TASKS AND I'VE UPDATED TOWARDS SHORTER TIMELINES

There is now an almost 2x higher probability of full AI R&D automation by the end of 2028. Strong performance in easy-and-cheap-to-verify SWE tasks that don't require new ideas will allow AI to substantially speed up AI R&D. A lot of the work in AI R&D involves these types of tasks, and AI can complete them significantly cheaper and faster than humans.

ANATOMY OF MERCOR'S DATA BREACH

Mercor is an AI-powered talent marketplace that connects software engineers, AI data labelers, and knowledge workers with companies seeking contract labor. The company claims it was recently breached due to a supply-chain attack on a popular open source package. However, there are several reasons to doubt that claim. Saying that it was affected by the supply-chain attack may be an attempt to deflect from deeper, more embarrassing security failures.

OPENAI'S $122B “VC ROUND” IS VENDOR DEALS, CONTINGENT CAPITAL, AND A GUARANTEED RETURN IT ARGUABLY CAN'T AFFORD

OpenAI closed a $122 billion investment round at an $852 billion post-money valuation at the end of last month. Amazon, Nvidia, and SoftBank accounted for $110 billion of that investment, while the remaining $12 billion came from a broader pool of institutional and individual investors. This article breaks down the numbers of the deal. Completely separate from the round, OpenAI is negotiating a joint venture with several private equity firms valued at roughly $10 billion pre-money with a guaranteed minimum return of 17.5%, plus early access to OpenAI models before general availability.

THE ANATOMY OF AN AGENT HARNESS

This post breaks down the agent harness, the full software infrastructure that transforms an LLM into a goal-directed, tool-using agent. Production harnesses use layered memory, verification loops, subagent orchestration, and structured tool execution to prevent context loss, errors, and silent failures. Frameworks like Claude Code, OpenAI Agents SDK, and LangGraph show that harness design alone can shift agent performance by 20+ ranks, making it the critical engineering layer around any LLM.

TURNING THE WEB INTO A FILESYSTEM

Code hallucinations are mostly a data problem, caused by outdated or fragmented training data. Nia's approach mounts documentation sites as virtual filesystems, letting agents grep, cat, and tree through docs in real time, so they code against current APIs rather than stale embeddings. This client-side, in-memory shell works with Claude Code, Codex, Copilot, Gemini, and OpenCode, providing a universal, low-latency interface for agents to browse structured information without complex tool schemas or container overhead.

WHAT TO KNOW ABOUT OPENAI'S IDEAS FOR A WORLD WITH ‘SUPERINTELLIGENCE'

OpenAI recently released policy proposals for a world with AI that far surpasses human capabilities. The proposals suggest creating an AI-centric tax system, a public investment fund focused on AI that could regularly distribute returns to Americans, and more. OpenAI has embraced President Trump's AI strategy, including his approach of limited guardrails for the industry, but it still wants to cooperate with the rest of the world in identifying dangerous AI systems and containing them. It supports giving the government a bigger role in evaluating models.

AI IS BECOMING AN OPERATING SYSTEM LAYER

AI must become an operating system layer across entire companies, reshaping product development, service delivery, and internal operations. This approach involves integrating AI into core functions rather than treating it as a mere feature. Companies not adopting this model risk inefficiency and losing competitive edge, making AI integration crucial for investment appeal.

THE TERM “AGI” IS ALMOST USELESS AT THIS POINT

The gaps between the different conceptions of the term 'AGI' are starting to damage our ability to think together about how to navigate the transition to a world with extremely advanced AI.
