Harness engineering: leveraging Codex in an agent-first world
OpenAI engineer Ryan Lopopolo on harness engineering: how Codex and agent-first workflows reshape the scaffolding around models, from prompts and tools to evaluation and production loops.

Software is still about thinking
Cursor’s head of design argues AI coding creates an illusion of speed without structure: unclear systems thinking now produces slop at scale, while clear architecture compounds into 100x leverage.

Minions: Stripe’s one-shot, end-to-end coding agentsUnattended coding agents that produce more than a thousand merged PRs a week at Stripe.
Stripe’s Minions are fully unattended coding agents that one-shot tasks end-to-end. Humans review the PRs; the agents write the code—here’s how the harness works.

Sparse Reward Subsystem in Large Language Models
Guowei Xu, Mert Yuksekgonul, and James Zou report a sparse reward subsystem in LLM hidden states: value neurons encode expected value, while dopamine neurons track reward-prediction error. The study finds these signals are robust across tasks and models and useful for confidence estimation and inference-time search.

A Mind Cannot Be Smeared Across TimeConscious experience, temporal windows, and why sequential computation may not suffice.
Michael Timothy Bennett argues that whether machines can be conscious depends not only on what they compute but when: augmenting Stack Theory, he proves existential temporal realisation over windowed trajectories does not preserve conjunction, so a mind cannot simply be smeared across time.

Bryan Cantrill argues that LLM-generated LinkedIn posts are immediately recognisable to readers who have seen much AI content, and that using AI to write in your name undermines authenticity and signals to others that your stated views may not be genuine. He urges people to write in their own voice.

The Graph Will Set You Free: Why Every Creative Tool Is Becoming a Node Canvas
Hirad Sab traces node-based creative tools from Sketchpad to modern AI canvases, arguing graphs are the right abstraction when generation becomes a networked, composable process.

Cache-to-Cache: Direct Semantic Communication Between Large Language Models
Fu et al. propose Cache-to-Cache (C2C): multi-LLM systems exchange KV-cache semantics directly instead of text tokens, aiming for richer inter-model communication with lower latency and token cost.

Trust Calibration for AI Software BuildersOriginal article link with an AI-written directory summary
Daniel Botha examines how software should earn an appropriate level of user trust. Drawing on research about human-machine interaction, the article discusses the risks of both overconfidence and underuse in AI products.

PhysicsForums and the Dead Internet Theory
David and Felipe of Hall of Dreams investigate PhysicsForums, a science community founded in 2001, and document widespread falsification of user posts there, treating it as a microcosm of the death of the human-written Internet.
