Introduction

Grok Imagine on the web now generates full songs from a text prompt and lets you lay them under the videos you already made — and SpaceXAI / xAI still has not announced it.

Since the evening of October 13 (MYT), multiple creators have posted screen recordings of a Music panel (sometimes labeled Original Audio) inside the Imagine workspace. Open a video, describe genre, mood, instruments, and tempo, and Grok writes lyrics and builds a track. You trim a section on the audio timeline, apply it to the clip, and the track lands in a reusable library.

What shipped (observed)

This is a closed, consumer-only feature — no public music API, no model card, and no entry on x.ai/news. The newest product post there is still “The X Subscription” (October 12). Accounts that have the panel can run it today at grok.com/imagine; rollout looks phased, so some readers will not see Music yet.

Concrete flow creators are documenting:

  1. Open Grok Imagine and select a video you created.
  2. Open the Music panel.
  3. Create a new track and describe the music (genre / mood / instruments / tempo).
  4. Grok generates the track with auto-written lyrics.
  5. Pick a section on the timeline and apply it to the video.
  6. Reuse favorites from the saved music library.

Early demos call the quality “Suno-like.” One creator claims the backend is Google Lyria 3; that is unconfirmed — treat the model identity as unknown until xAI says otherwise.

Why it matters for audio makers

If you already storyboard in Imagine, soundtrack generation inside the same canvas removes a hop to Suno, Udio, or a separate stem tool. For anyone waiting on an API or open weights: this is still a gated UI feature, not a developer surface.

Label this as an observed rollout / soft launch, not an official ship notice. When xAI posts a changelog or blog, we will update the facts (model name, availability, pricing).

Conclusion

Grok Imagine’s quiet Music panel is the first clear in-app text-to-music path tied to Imagine video — live for many accounts since October 13, still without an official announcement. Try it on grok.com/imagine if the Music control shows up for you; otherwise watch for the phased rollout to widen.
