Huge respect to @Guodzh and @imhaotian and everyone on the team for building a culture focused on solving hard problems, shipping better models, and improving usability and user experience.
Ideas are cheap, talking is easy, and titles/narratives are easy after the fact. Being solid and making things actually work is the hard part.

@EthanHe_42 worked with me and @imhaotian for half a year on Grok Imagine. I don't think he was being intentional overclaiming here, but the internet narrative quoting him as the "lead" was werid. It was really driven by @imhaotian most of the time.
Good times — especially that intense three-month sprint at the start. Huge credit goes to @imhaotian and several other key people like @zeliu_ @jathushan @ZhibeiM @hexiang @JackCaiXun @chaitu, and later @jia_xuhui @YknZhu, along with many others — especially the latest Grok Imagine 1.5.

A lot of improvements have been made. It’s worth a try.
Grok-Imagine-Video-1.5-Preview (720p) has landed #1 in the Image-to-Video Arena!
This is a massive 52 pt improvement over Grok-Imagine-Video (720p), surpassing the best video models Seedance-2.0 and HappyHorse.
Congrats to @xAI and @elonmusk on this big achievement!

Your entire creative workflow just collapsed into one infinite canvas.
In @imagine Agent Mode, you can brainstorm, write, generate and edit images, then turn them into videos without leaving the page.
Try it at grok.com/imagine, on desktop.

Grok Imagine now has dramatically improved lip sync and sharper audio quality on all image-to-video generations.
Dialogue tracks the mouth. Sound matches the scene. Your videos look and sound the way you imagined them.

Grok Imagine image-gen and image-edit is faster and better than Nano Banana!
The new @xAI Grok-Imagine-Image model is a Pareto-optimal model in Image Arena:
The Pareto frontier tells us which model has the highest Arena score at each price point. @xAi’s latest models have improved the frontier, giving optimal performance in the mid-price tier. For a wide range of prices between 2c and 8c per image, @elonmusk’s @xAI has the leading model, delivering the maximum performance.
Top models on the Pareto frontier for Image Arena (Single Image Edit):
- @OpenAI: GPT-Image-1.5-high-fidelity
- @xAI: Grok Imagine Image Pro
- @xAI: Grok Imagine Image
- @bfl_ml: Flux 2 Klein 9B
- @bfl_ml: Flux-2-Dev
- @reve : V1.1 Fast
See thread for how the frontier changes for Text-to-Image 🧵

BREAKING: @xAI’s Grok-Imagine-Video now #1 in Video Arena!
For the first time, Grok-Imagine-Video-720p takes the top spot on the Image-to-Video leaderboard, overtaking Google’s Veo 3.1 while being 5x cheaper. Its 480p version released a few days ago ranks #4.
Huge congrats to @xAI team and @elonmusk on this incredible milestone!

very cool!

We just unlocked Grok Imagine's real potential.
xAI built the model. We figured out how to actually use it - fluid motion, cinematic POV & multi-shot control.
@elonmusk you're gonna like this.

This is the second #1 I achieved at @xAI! (the first one was Grok 3 with my best post-training friends ;).
After shipping Grok 4, I jumped into something completely new to me — video generation with @imhaotian and @zeliu_. In just 6 months, the team built everything from 0 to 1 to #1.
How did we make this happen? For me, it's mostly about the best intuition and execution — and having the best friends to work with. My best take on both achievements is that we should respect users and focus on things that can scale.
This is just the start. Stay tuned for what we’ll achieve next.

We spent the past three months polishing the model quality and optimizing the user experiences. Grok Imagine now produces more videos every day than all other companies combined and it ranks #1 on leaderboards! I’m extremely proud of what the team has achieved. We’re the best!
