What each AI video model's release notes say changed

How to read a model line's page

A line page lists every entry for one maker's models, oldest first, with four kinds of source: the maker's own note, a platform's arrival note, an undated row from a model list, and an undated row from a platform's tier list. The Source column says which. As of 2026-09-25.

Where this note's examples come fromThe examples in this note come from 3 entries across 3 model lines.ExamplesKling AIMidjourney videoSeedanceEvery layer: 1 entry
Fig. 1 Each example links to its line page.

The count at the top reflects how the maker writes notes. Kling's thirty-six entries come from a detailed API log; Midjourney's four from a blog. Read the versions list to see the steps, and the kinds of change to see where the notes spend their words.

The timeline at the top of the entry table shows the rhythm. Some lines post in bursts around a launch; others post a little every few weeks. A long quiet stretch on a line with a detailed log is worth noticing; on a line that only posts launches, it is normal.

Each version with three or more entries has its own page, and each kind of change with three or more entries for the line links to a page for that pair.
