What each AI video model's release notes say changed

Which AI video release notes claim better motion?

Motion claims come with new models and updates: Runway's Gen-3 Alpha in July 2024, Wan 2.1 in January 2025 and Wan 2.2 in July, the Firefly Video Model's improved motion fidelity in July 2025, Hailuo 2.3 in October and HappyHorse 1.1 in June 2026. None of the notes gives a measure. As of 2026-09-25.

Inclusion rule. Entries whose note bears directly on the question. Order. By date, oldest first; undated rows last.

A motion claim describes how the output is said to look: smoother transitions, larger movements, physics that hold together, bodies and faces that move naturally. It cannot be checked from the note itself, only by trying the model on the same prompt before and after.

Controls over motion are a different kind of entry and have their own question: how much moves, and where.
