The set of pages a process actively needs in memory. Everything else is noise.
Keep only what you need in memory.
A weekly briefing on AI and the systems around it — research that survives contact with production, tooling worth the migration, and the engineering practice forming around all of it.
One email, every friday morning. Read in five minutes. No roundups of roundups, no thread screenshots, no course upsell at the bottom.
Contents
Research that survives contact
Papers and model releases that change what you can actually build, with the hype filtered out.
Tooling and infrastructure
Inference, evals, agents, vector stores, and the unglamorous plumbing that decides whether any of it ships.
Engineering practice
How teams are folding models into real codebases — the patterns that hold up and the ones that quietly do not.
The occasional strange thing
One link a week with no business case whatsoever. It stays.
Specimen
What lands in your inbox. This is an excerpt — issues run a little longer, and end with the strange thing.
The one thing
Everyone shipped an agent framework this week. Two of them are worth your afternoon, and the difference comes down to how they handle a tool call that fails halfway through.
A quiet paper on context compaction
arXivBeats naive truncation by a wide margin and takes about forty lines to implement.
Postgres as a vector store, one year on
Engineering blogAn honest retrospective, including the part where they moved half of it back.
The eval suite that caught a regression nobody else did
GitHubSmall, mean, and worth stealing wholesale.
