What we track
We record model debuts, significant versions, open weights, and capability changes, grouping models from the same launch. Model pages collect specifications, context, family links, and relevant history.
Sources and verification
Release dates and key specifications prioritize vendor blogs, developer docs, model cards, official repositories, and author papers. Relevant sources appear at the bottom of each model page.
Missing information
Parameter counts, context lengths, and licenses are omitted when reliable public information is unavailable. Conflicting figures are not presented as settled facts.
Coverage
The current edition covers 389 models and 385 release milestones across 50 model families in language and agents, image generation, and video generation, with coverage since 2018 and events through 2026-10-17.
