  • Benchmarks are not the same thing as usefulness

    A benchmark is a proxy. It stands in for a capability that is hard to measure directly, and like all proxies it can drift away from the thing it was meant to represent once people start optimising for the number.

  • The new startup constraint: a compute budget

    For a generation of software companies, marginal cost was effectively zero. Products built on large models do not have that property: every request has a price, and that price shows up in the gross margin.

  • The grid is the bottleneck everyone underestimated

    Building generation is now comparatively fast. Connecting it is not. In this sample analysis, interconnection queues rather than construction timelines are the binding constraint on new capacity.

The main file

All coverage

Picked for you

You have not opened a story yet, so these are simply the newest. Read a few and this list changes.

What actually runs here

How it works

Summaries

Every article carries a three-line brief, extracted from its own sentences. Nothing is rewritten, so nothing can be invented.

Read aloud

Articles play through the browser's own speech engine, highlighting each sentence as it is spoken. No audio files to host.

Related by content

Stories are matched on shared vocabulary rather than on category, and each card shows the words the two have in common.

For you

The feed reorders itself around what you actually open. The history stays in your browser and never leaves the device.
