METHODOLOGY

Sources and publication rules

Headlines and story excerpts come from public feeds or page metadata and always link to the source. Publisher claims are not independently verified. AI selects brief passages from this edition’s source material; it cannot rewrite their wording or add claims.

Newsroom

We monitor OpenAI, Anthropic, Google AI, DeepMind, xAI, Mistral, MIT Technology Review, Effort, TechCrunch AI, Ars Technica, The Verge AI, and Simon Willison. Reuters and AP are excluded until a verifiable public RSS or Atom source is available. We do not scrape paywalls.

Edition rules

The window is the prior 36 hours. Duplicate URLs are removed. Closely matching event headlines are grouped with all original source links; uncertain matches, different companies and different model versions remain separate. A new edition requires at least three distinct developments from two sources and a valid AI selection of at least two source passages. Failures keep the previous complete edition live.

What gets priority

Transparent headline and excerpt rules prioritize model and tool releases, legal developments, research and safety, and infrastructure. Multiple publishers covering an event add weight; publication time breaks ties. Commentary, speculative headlines and promotional updates remain in further reading rather than filling featured slots. Previously included links and headlines receive less weight and are labeled. This ranking is an editorial heuristic and can miss nuance; it does not verify a publisher’s claims. Up to five stories are featured, with at most two per publisher. We do not fill empty slots with lower-priority posts.

The source brief

AI chooses two or three featured developments by source ID. The publication then copies each source’s opening sentence or headline, including attribution and uncertainty, and attaches that source’s link. Selections outside the candidate list, repeated events and malformed output fail publication. No model-written claim or speculative trend line is displayed. Older editions without this format use source passages in the page’s brief instead of their earlier generated summaries.

Investor tracker

Attributed public commentary is monitored through a16z News, Sarah Guo, Sequoia Capital Stories, and Invest Like the Best appearances featuring Gavin Baker. The latest item per investor within 30 days of the edition is shown first. Earlier and additional items remain in a collapsed section, up to 120 days old, with their publication dates and age relative to the edition. This section is informational, not investment advice.

Schedule

The Worker attempts publication at 6:15 a.m. America/Chicago every day and retries at 6:30 and 6:45 only while that Chicago date has no complete edition. UTC cron triggers are gated using Chicago local time so daylight-saving changes do not shift the edition.

Model economics

Model scores and prices come from the public Arena Text leaderboard, with a checked-in snapshot only when live parsing cannot yield a complete set. Blended price is (3 × input + output) ÷ 4. The Pareto frontier maximizes score and minimizes input price per million tokens. Models without a positive input price are omitted from the logarithmic chart. Blended price remains available in the table for comparison. Company, country, logo, and license metadata use a sourced registry; unmapped values remain Unknown.
