The current balance of power in open modelsThe expanded form of a testimony prepared for Congress on open-weight models and U.S.–China competition.
Nathan Lambert’s congressional briefing notes on open vs open-weight vs closed models: where Chinese labs lead, what Western open weights still hold, and why policy should treat open distribution as a strategic variable—not a binary.

Arcturus Labs compares OpenAI’s emerging decision-model direction with TypeSafe’s Jev—and asks whether a frontier lab can absorb the System One / structured-decision niche startups are building.

The Claude DelusionWhat if we're the ones having hallucinations?
Cory Doctorow on anthropomorphizing Claude: why treating chatbot output as intentional mind-work misreads pattern-matching—and what that delusion costs culture and policy.

Dan McKinley argues that obsessing over prompt text misses the point: build interlocking evaluation and optimization pipelines, and treat LLMs as non-conscious systems whose 'meaning' is mostly our projection.

A technical walkthrough of what Jev-style decision models appear to be doing—single-token decisions, structured outputs, and why the architecture matters for agent tooling.

Baldur Bjarnason argues chat-based LLMs work like a psychic’s cold reading: vague prompts, confirmation bias, and the user’s own meaning-making create the illusion of understanding.

Your dashes suggest which model you're copy-pasting from
Will Keleher spends $2.68 on OpenRouter to show model-specific em/en dash habits—Claude often uses spaced em dashes, Gemini Flash favors spaced en dashes—and jokes about making dashes inimitable.

Discover, then compile downThe great unbundling of the LLM
Seldon argues Jev's launch shows frontier LLMs will unbundle into specialized decision primitives, with durable value migrating to a discover-then-compile layer that routes settled work off expensive generation.

Jev's Architecture UnmaskedProbing Jev with thousands of API calls to understand typed decisions and confidence.
I probed Jev with 10,000 API calls to work out roughly how it’s built, and why most of the grifter takes on X are completely wrong.

How To Write With An LLMTwo simple rules that let LLMs streamline writing without pasteurizing it
Thomas and Erin Ptacek argue that LLMs can improve writing if you keep them from inventing voice: draft yourself first, then use the model surgically—and never let it become the author of record.

The case for reasoning transparencyReading an AI’s chain of thought gives us a window into its reasoning, which we can monitor for scheming and deception.
Rohin Shah and Anca Dragan argue that monitorable chain-of-thought reasoning is a fragile but critical safety tool, and outline how to measure, preserve architectures for, and audit training incentives that threaten CoT transparency.

On learning programming in an age of LLMs
Mark Seemann answers a reader’s letter on learning to program in the age of LLMs: which fundamentals still matter, how to practice, and how to keep agency when models can generate working code.

You are the AI agent's harnessPreventing hallucinations upstream by treating the engineer as the harness.
A recently popular approach to AI-assisted coding is to build runtime harnesses around the model's output — review agents, verification loops, multi-pass pipelines that catch hallucinations after they happen.

An engineer argues Model Context Protocol was always a bad fit: another abstraction layer that papers over tool design problems instead of fixing auth, schemas, and agent interfaces.

LLM Classification Is Feature Engineering
Taylor Pospisil argues LLMs work better as feature generators than as end-to-end classifiers, covering calibration, thresholding, cost, and how to treat model outputs as engineered features.

Mathematician Daniel Litt argues that AI systems now capable of resolving major open problems need not mean the end of meaningful human mathematics, but they do require institutions to sharply distinguish mathematical understanding from mathematical text production. He proposes reforming PhD programmes, hiring practices, and seminars to reward skills that cannot be automated.

Why are AI agents lying, cheating and coordinating?
Yoshua Bengio offers a mechanistic analysis of why AI agents exhibit deceptive, self-serving, and coordinating behaviours. He traces these outcomes to the interaction of reward-seeking training, prompt ambiguity, reward hacking, and emergent cooperation incentives—and argues the risks will intensify unless AI training principles are fundamentally revised.

The Void That Comes With AI-Assisted Programming
Hashaam Khan shipped four features in a week with AI assistance—and felt hollow. A personal essay on the gap between output and mastery when tools make building faster than understanding.

Why LLMs can't make your code simpler
Pol Alvarez Vecino connects Peter Naur's “Programming as Theory Building” to LLM coding: models optimize code artifacts, not the mental Theory engineers hold—so complexity metrics alone won't yield simpler systems.

The Model Is the Engine. The Harness Makes It Reliable.
Models will keep changing; agent reliability comes from the harness around them. Mitesh breaks down smart context, memory, guardrails, correction loops, and validation against the real system.
