xAI Opens Grok Imagine Video 1.5 to General Availability, Adds Fast Model
The general release of Grok Imagine Video 1.5, which previously achieved top benchmark scores as a preview, and the simultaneous launch of a significantly faster variant put a production-ready video generation tool into wider use.
Reporting from 1 sources: GIGAZINE.
xAI has made its video generation AI Grok Imagine Video 1.5 generally available through the Imagine API, retiring the preview version. The company also launched Grok Imagine Video 1.5 Fast, a model that generates a 6-second 720p clip in about 25 seconds, nearly halving the time of the previous model. The fast model is available in the web, iOS, and Android versions of Grok.
The preview version Grok Imagine 1.5 Preview, which xAI released in June 2026 and which scored first or second place in multiple AI benchmarks, is now being shut down. Its replacement, Grok Imagine Video 1.5, is available through the Imagine API. Separately, the fast model Grok Imagine Video 1.5 Fast is live in the web, iOS, and Android versions of Grok. xAI said it plans to roll out new features over the coming days, including Projects in the left sidebar, Multi-Agent for running multiple agents in parallel, and a Search function for the library. Creative experimentation platform HEAVY PULP has already used the fast model to produce and publish videos in collaboration with xAI.
