What's moving through AI, ranked by lead time.
Radar is an hourly index of what's moving through the AI ecosystem, ranked by where each story sits on the lead-time gradient: papers become repos become community threads become analysis. The earlier a story is caught, the more head start you have before the crowd. Every row carries its receipts — which source saw it first, how many independent sources have it, how long ago — so the ranking explains itself. It's the public face of the same pipeline that feeds Vlad's Newsletter.

668 stories entered the watched feeds in the last 24 hours — 369 in papers, 4 in repos, 269 in community, 26 in analysis. The scored board skews to Community (40 of 40). 4 stories are heating across independent sources, and the median lead across the ledger's 24 observed fires is 5h — measured, not estimated. Freshest receipt, 1h ago: caught in Hacker News front 4h before Stratechery carried it. The oldest survivor has held the board for 10h.

How Radar works
The gradient. Stories travel through the AI ecosystem in a rough sequence: they appear first in papers (arXiv, Hugging Face) or repos (GitHub), then surface in community discussion (Hacker News, Lobsters, LessWrong), then get interpreted in analysis (operator newsletters and essays). Radar ranks by where a story sits on that gradient. The earlier it is caught, the more lead time you have before it reaches consensus. The spectrum at the top of the page shows the last 24 hours of that flow — every story that entered the watched feeds, counted at the station where it first appeared.
The score. Each story gets a recency-decayed signal score. Every source tier carries a weight and a half-life, so live signal moves fast and fades fast while analysis sources move slowly and stay relevant longer. A story scores higher when two or more independent source families carry it — corroboration, not popularity, which is why five feeds of the same site count once. A small bonus applies when a story has visibly climbed the gradient. Stories past their tier's maximum age expire from the board.
Heating and lead time. A story is heating when it has surfaced in two or more independent source families. When the same story is observed first at an earlier stage and later at a higher one, Radar records the gap in hours — for example, seen on arXiv fourteen hours before it reached the Hacker News front page. That gap is the reader's lead time, and it is a measured span, never an estimate.
The honesty rule. Every value on this page is an observed fact from the feed log — which source carried a story, when, and how many. Radar makes no claim about what a story means; that is the newsletter's job. When a reading does not exist yet — no stories heating, nothing upstream — the page says so rather than inventing one.
Questions
- What is the lead-time gradient?
- The path a story travels through the AI ecosystem: it appears first in papers (arXiv, Hugging Face) or repos (GitHub), then surfaces in community discussion (Hacker News, Lobsters, LessWrong), then gets interpreted in analysis (operator newsletters, essays). Radar ranks by where a story sits on that path and how far it has travelled.
- What does the lead-time spectrum show?
- Every story that entered Radar’s watched feeds in the last 24 hours, bucketed by the gradient station where it first appeared — papers, repos, community, or analysis. It is the day’s flow through the whole watched ecosystem, not the composition of the scored top 40 below it: a paper counts in the flow the moment it is observed, even while its signal score is still too low to earn a board row.
- How is Radar ranked?
- By a recency-decayed signal score: each source tier has a weight and a half-life, a story scores higher when independent source families corroborate it, and a small bonus applies when a story has visibly climbed the gradient. Stories past their tier max age expire from the board. Popularity on a single site is not corroboration.
- How often does Radar update?
- Hourly. The page is server-rendered and a frozen snapshot is archived at a dated permalink each day, so the record is both current and citable.
- What does "heating" mean?
- A story has surfaced in two or more independent source families — not two feeds of the same site. It is corroboration, not popularity.
- What is the lead time reading?
- When the same story is observed first at an earlier gradient stage and later at a higher one, Radar records the gap in hours — for example, seen on arXiv 14 hours before it reached the Hacker News front page. That gap is your lead time. The fires ledger is rolling: a fire ages out with its story, roughly 45 days after the story’s last sighting, so the median lead always describes recent motion.
- What sources does Radar watch?
- Around 78 verified feeds across five tiers: live signal (Hacker News, Lobsters, GitHub trending, arXiv, Hugging Face papers), AI labs and firehose blogs, operator newsletters, contrarian essayists, and primary analysis. The registry is curated; aggregators are used only to corroborate a story, never to be the first to report it.
- Is Radar the newsletter?
- No. Radar shows what is moving; the newsletter tells you what to do about it. Radar is the free, public funnel; Vlad’s Newsletter is the weekly operator read.
- The spectrum band
- A filled flame tick is an early, lead-time-rich stage; a hollow tick is a later stage; a hollow ring on an empty span is a station with nothing on it yet.
- Signal class
- The tier chip: Live Signal moves fast and decays fast; analysis sources stay relevant longer. The ranker weights each accordingly.
- heating
- The same story in two or more independent source families — not two feeds of one site.
- seen in / via
- How many families carried it, or the single source that did.
Once a week, the operator read on what actually changed and the move it calls for. No digest, no hype.
