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.","whyItMatters":"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.","webCardHtml":"\u003cp\u003eThe 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.\u003c/p\u003e","blueskyPost":"xAI's fast model generates a 6-second 720p clip in 25 seconds, nearly half the time of the previous preview. The speed improvement is the key differentiator for real-time use cases.","twitterPost":"The fast model cuts generation time nearly in half. Speed, not quality, is xAI's differentiator.","threadsPost":"xAI's video generation update focuses on speed. The new fast model produces a 6-second 720p clip in about 25 seconds, roughly half the time of the preview version. That makes it viable for iterative workflows where latency matters more than resolution.","newsletterBlurb":"xAI opened Grok Imagine Video 1.5 to general availability through the Imagine API, retiring the preview version.
