THE AGENT STACK BET

Most 'production agents' shipping today feature custom plumbing, fragile session logic, shared service accounts, and weak security models. While models and tools have gotten dramatically better, there is a stack ceiling that is quietly creating a governance and reliability gap that agentic systems can't grow through. The current stack has excessive agency, with agents leaving a trail of corrupted state behind them. This article suggests four architectural bets teams should consider to move to the next generation of agentic systems.

OUTPUT ISN'T DESIGN

Many people mistake design as the act of producing something. However, the hard part of design is actually understanding the problem enough to know what and how something should exist at all. There is use and place for tools, but the tools aren't part of the design process. Design is the search for a good fit between a form and its context. Good design considers human needs, technical constraints, conflicting requirements, habits, edge cases, and easy-to-miss relationships that require time to identify.

INSIDE NOTION

Notion is a company built on ideology, brand, and community rather than technical edge. The company's software gives users blank pages they can customize with modular blocks into whatever they want. Notion became the canonical product-led growth company after it first took off in 2018, propelled by brand ambassadors, influencers, and fandoms across social media. This article explores how the company works and how it became one of the top 10 most-used AI products in the world, despite not being 'AI-native'.

OPENAI STARTS OFFERING A BIOLOGY-TUNED LLM

GPT-Rosalind is a large language model developed by OpenAI specifically trained on common biology workflows. It is able to access major public databases of biological information. The model can suggest likely biological pathways and potential drug targets. It has been tuned to be more skeptical so it can tell users when something is a bad drug target. Access to the model is limited to selected US-based entities via OpenAI's trusted access deployment structure.

PHYSICAL INTELLIGENCE, A HOT ROBOTICS STARTUP, SAYS ITS NEW ROBOT BRAIN CAN FIGURE OUT TASKS IT WAS NEVER TAUGHT

Physical Intelligence, a San Francisco-based robotics startup, has published new research showing that its latest model can direct robots to perform tasks they were never explicitly trained on. The new model, called π0.7, is an early but meaningful step towards a general-purpose robot brain. The model still can't execute complex multi-step tasks autonomously from a single high-level command, but it can be verbally coached to perform new tasks without additional data collection or model retraining. It is still in a research phase and not yet ready to be deployed as a product.

UPDATES AND ANNOUNCEMENTS

Cloudflare just dropped a series of announcements for Agents Week 2026. Cloudflare is building a unified inference layer for agents that will let developers call models from over 14 providers. Cloudflare's Email Service, which allows users to send, receive, and process email natively with agents, is now in public beta. Artifacts is a Git-compatible versioned storage built for agents.

THE CLIP ECONOMY

Clips - snippets of long-form content - have taken over the entire media ecosystem. TBPN, a podcast recently purchased by OpenAI for $200 million, only draws in around 7,000 views per episode. However, the average TBPN clip receives around 257,000 views. TBPN bakes ads directly into its clips, which helped it generate $5 million in revenue last year. Clips are now the main product for a lot of media, rather than a byproduct.

MUSK ASKS SUPPLIERS TO MOVE AT ‘LIGHT SPEED' ON NEW CHIPMAKING PLAN

Elon Musk's Terafab team has reached out to chip industry suppliers for price quotes and delivery times for a variety of chipmaking gear. The outreach suggests Musk is continuing with the project in the face of scepticism from the semiconductor industry. Musk's representatives have asked for speedy price estimates while providing minimal information about the products to be made. The project is offering to pay a considerable amount above quoted figures if suppliers give Terafab priority.

SIRI ENGINEERS SENT TO AI CODING BOOTCAMP AS APPLE PREPARES TO DELIVER SIRI OVERHAUL

Apple is sending a large portion of its Siri engineers to a multi-week bootcamp on learning how to code with AI. Around 60 members of the Siri development team will continue working on Siri, with another 60 evaluating how the assistant is performing. Apple is expected to unveil a smarter, more capable version of Siri in two months at WWDC. The new Siri is under testing to ensure it meets Apple's safety standards and can interpret and execute commands from users.

ARTEMIS II WAS A BLOCKBUSTER. LANDING ON THE MOON WILL BE A LOT HARDER

The Artemis III mission next year will help NASA and its contractors set up an attempt at one or more visits to the moon in 2028. Both SpaceX and Blue Origin have run into delays in developing spacecraft for the missions. A landing operation with astronauts within the next few years may not be achievable. Both companies have key tests coming up that will inform their lunar work and vehicles.

FRONTIER SYSTEMS FOR THE PHYSICAL WORLD

The paradigm is shifting to robot learning, autonomous science, and human-machine interfaces. These are not entirely separate efforts and thematically form a group of emerging frontier systems for the physical world. They share common technical primitives and are mutually reinforcing in ways that create compound dynamics across domains. These domains create a structural flywheel for extending AI into the physical world. This post looks at the technical primitives underlying these domains and examines why they present frontier opportunities.

WHY CHATGPT CITES ONE PAGE OVER ANOTHER (STUDY OF 1.4M PROMPTS)

ChatGPT is an aggressive editor. It favors its general search index, uses semantic similarity to select and cite sources, and treats Reddit like a textbook. The pages that get cited are the ones whose titles and content match the questions ChatGPT is asking behind the scenes, and that surface through the right retrieval channel.
