SpaceXAI 发布 Grok Imagine Video 1.5 Lite，跻身视频生成榜第 17 名
SpaceXAI 出了个便宜版视频模型，排名超过 Veo 3.1 但价格只有三分之一，10 秒 1080p 一分钟内就能生成，API 上就能调。
SpaceXAI 推出低价版视频生成模型 Grok Imagine Video 1.5 Lite，支持 1 至 15 秒、480p 到 1080p 的文生视频与图生视频。在 Artificial Analysis 的 AA-Video-T2V v2.0 榜单上排名 #17，超过 Google 的 Veo 3.1，而价格约为其三分之一。端到端生成 10 秒 1080p 视频的中位耗时为 60.5 秒，是该质量档位中最快的模型。1080p 定价 $0.14/秒，是 Grok Imagine Video 1.5（$0.25/秒）的 56%，720p 和 480p 分别降至 $0.03/秒和 $0.02/秒。模型已通过 SpaceXAI API、fal 和 Vercel AI Gateway 提供。
Grok Imagine Video 1.5 Lite lands at #17 on both AA-Video-T2V v2.0 leaderboards and takes a position on the Pareto frontier for quality and speed
Grok Imagine Video 1.5 Lite is the new lower-cost model in SpaceXAI's Grok Imagine video family. It generates Text to Video clips of 1 to 15 seconds at 480p, 720p or 1080p, and also supports Image to Video.
In the Artificial Analysis Video Arena, Grok Imagine Video 1.5 Lite ranks #17 on both AA-Video-T2V v2.0 and AA-Video-T2V-Silent v2.0, ahead of Google's Veo 3.1 at about a third of its price. It comes closest to the frontier in Multi-Scene & Narrative, Lighting & Materials and Text Rendering, and in the Architecture & Real Estate and Consumer use cases.
In our end-to-end generation time benchmarks, it is the fastest model at its level of quality, at a median of 60.5 seconds for a 10 second 1080p clip, which places it on the quality and speed Pareto frontier.
SpaceXAI prices Grok Imagine Video 1.5 Lite at $0.14 per second of 1080p video ($8.40 per minute), the resolution we evaluated. That is 56% of the $0.25 per second that Grok Imagine Video 1.5 costs at 1080p. Lite drops to $0.03 per second at 720p and $0.02 per second at 480p.
Grok Imagine Video 1.5 Lite is available via the SpaceXAI API, on fal at the same prices, and on Vercel AI Gateway.
Congratulations to @SpaceXAI & @elonmusk on the release!
