releaseDate is the Gemini API paid-preview launch (Google Developers Blog, Oct 15 2025); Vertex GA ids veo-3.1-generate-001 and veo-3.1-fast-generate-001 released Nov 17 2025 (retirement 'November 17, 2026 or later'). Veo 3.1 Lite launched Mar 31 2026 (Vertex preview id dated Apr 2 2026). maxDurationSec is a single generation; extension reaches 148 s. Fast: up to 4K on Gemini API docs but Vertex lists 720p/1080p only. Lite: 1080p max, no reference images or extension. No newer Veo found: Google's Gemini API docs and DeepMind's Veo page still presented Veo 3.1 as of the last check, and Google now recommends Gemini Omni Flash as the default video model. Scores: LMArena 'veo-3.1-audio' 1364 (other rows: veo-3.1-audio-1080p 1362, veo-3.1-fast-audio 1362); AA Veo 3.1 965, Veo 3.1 Fast 960, Veo 3.1 Lite 946. The Gemini API preview ids veo-3.1-generate-preview, veo-3.1-fast-generate-preview and veo-3.1-lite-generate-preview were shut down on 2026-10-22 (ai.google.dev Veo and video docs); Google points developers to gemini-omni-1.1-flash or the Vertex/Gemini Enterprise Agent Platform GA ids.
