Changelog

The front page opens on the Acceleration timeline

The right side of the front page's first screen now shows Acceleration's "Right now": the latest illustrated milestone, which opens the timeline.

Along the foot of the first screen runs the whole log timeline from the Big Bang to the forecasts, with a needle at today and four readings below it: the Kardashev index, human primary power, compute per dollar and world population. Today's lead story moves just below, under "Today, on the curve"; trending and picks are unchanged.

Trending event pages now share the front page's night look, and the line under the title reads "Updated … ago".

Frontier now shows its readings

A row of readings sits under the page header: the leading model's consensus index and price, how many times cheaper the same intelligence has become, and today's Kardashev rating.

The cards below draw their content: the top five models with their makers' logos and score bars, those models' input and output prices on a log scale, the cost of intelligence as price steps for each capability tier, and the Kardashev rating on its scale.

News now comes with the original's preview image

Web reports show the original page's own share image on their cards and article pages, credited to the source and linked to the original. Site-wide default images and small images are left out.

X posts now show their own text and images on cards and article pages.

A clearer menu, and a new Frontier page

The top bar is now Picks, Daily, Acceleration and Frontier. Frontier is a new overview that brings together the model leaderboard, model prices and the cost-of-intelligence index, along with today's Kardashev rating.

More is grouped into Read, Understand e/acc, Make, Yours and This site, with a line on what each page holds. Trending, All news and Products now live there. The top bar gains search and Subscribe buttons, and the language is a two-button English / Chinese toggle. The phone tab bar matches the desktop.

Daylight in the ten era workshops

Nine workshops — writing, iron, printing, steam, electricity, flight, logic, docking and networks — now have real window openings, so sunlight falls across the floor and apparatus in window-shaped patches, with lighter walls and a view of sky and hills. The observatory stays a night scene, lit by moonlight and lamps.

Sharper artwork across Chronicle

All 154 era and event artworks now have enhanced versions for different screens, up to 3,840 pixels wide. Workshop panoramas and the engineering illustration have also been enhanced, preserving their original framing.
