Change log
- — Verified current against Runway's API model docs: Gen-4.5 is still the newest Gen model and no Gen-5 exists. Aleph 2.0 (2026-06-02) is Runway's newer flagship but is an in-context video editing model, not a Gen successor. Swapped Sora 2 out of the rivals weakness (OpenAI shut it down 2026-09-24) for Kling.
- — Verified current against Runway's model docs and changelog, which dates Gen-4.5 to 2025-12-11 — matching this entry exactly. No Gen-5 exists. Aggregator claims of a March 2026 launch contradict Runway's own changelog and were rejected.
- — Updated from Gen-3 to Gen-4.5 (released 2025-12-11) per Runway changelog. (Interim: Gen-4 / Gen-4 Turbo 2025-04.)
- — Initial entry.
