The open era moved — and took the evidence with it

Epoch AI · Notable AI Models · CC BY 4.0 · 1950–2026 · 1,078 models

The first dashboard here that is not frozen. A connection-backed Postgres dataset on a daily refresh that rebuilds its wasm extract. It reads as of 2026-09-30, the newest publication date in the rows, and that date moves on its own.

A dashboard titled "The open era moved — and took the evidence with it". Three statistic cards read "the open share of released models" (100.0% in 2019 to 35.0%), "it did not fall everywhere — since 2024" (China 67.8% against the USA’s 21.2%) and "the largest training run anyone has confirmed" (3.8×10²⁵ FLOP, Llama 3.1-405B, open weights). Below them a line chart of the open-weights share by year falling through a dashed "half" line in 2024, with grey bars behind it for the number of models released each year; then a log-scale scatter of every training run coloured by whether the weights are open and faded by how confident the figure is, a list of the eight closed models believed to be bigger than anything confidently measured, country and confidence bar rows, and a median-training-cost chart whose coverage bars collapse after 2023.

La pregunta que responde

Epoch AI tracks every notable model since 1950. Over that record, did openness follow capability?

Los datos, y de qué periodo

Training compute, training cost in 2023 dollars, accessibility, country, and Epoch’s own confidence in each figure.

Qué vuelve

1,078 rows × 19 columns.

Qué fue difícil

The denominator changes the finding. Epoch marks 287 models “Unreleased”, mostly academic work that never shipped. Counted as closed, the open share peaks at 56% and drifts to 33%. Counted out, as here, it goes from 100% in 2019 to 35%.
