The On The Radar AI trend puts two people in a neon-green radio booth, rapping side by side at one microphone, copying a "679" performance posted on 17 April 2026. You can make your own from two photos on the On The Radar AI trend page, and the result is a 15-second video with the trend sound already on it. This guide answers the questions people ask most about where it came from, what the song is and how to get a good result.

Where does the On The Radar AI trend come from?
It comes from one clip. On 17 April 2026 the On The Radar Radio account posted a booth performance of "679" with Fetty Wap and Monty, and that post became the template everyone copies. The first tutorials on putting your own faces into it appeared in early May 2026, and a wave of CapCut face-swap templates took it mainstream from late August.
The On The Radar AI trend page on videosi keeps the dates, the sound and the current stage in one place, so you can check them before you post.
What is the green booth in the video?
The booth is the set of On The Radar, a hip-hop freestyle series: a small radio studio lit in neon green, with a glowing ring sign on the back wall, acoustic panels on both sides and one microphone on a stand. In the trend clip two performers stand shoulder to shoulder at that single mic, which is why every remake keeps the green light and the ring sign.
The framing is part of the joke. Two people sharing one mic, one throwing an arm up on the first beat, is the shape the AI versions repeat.
What happens second by second in the clip?
The reference clip is about 15 seconds. It opens on a wide two-shot where the left performer throws an arm up while the right performer raps into the mic. Both then bounce on the beat with open hands and trade lines, they point at each other and at the lens, the camera pushes in tight on the microphone with the left performer ducking in beside the other, and it pulls back to the two-shot for the finish.
That cut timing is what makes a remake feel right, and it is why videosi copies it from a real performance instead of asking a model to improvise it.
What song is used, and how old is it?
The sound is "679" by Fetty Wap featuring Remy Boyz, released on 29 June 2015. It reached number 4 on the US Billboard Hot 100 and is certified 9 times platinum in the US, according to its Wikipedia entry. The booth version with Monty is a separate performance recorded for On The Radar.
TikTok labels many posts "679 (feat. Remy Boyz)" by Fetty Wap, and tapping that label is the quickest way to reuse the same audio on your own post.
Why is a 2015 song trending in 2026?
Two things lined up. Fetty Wap was released from federal prison in early January 2026 and put out a new album in March, so his name was already in the feed, as his Wikipedia page records. Then a face-swap template made the booth clip easy to remix with friends, couples and pets, and remixes spread faster than the original ever did.
The nostalgia helps too: people who heard "679" in 2015 are now the ones making and sharing the edits.
How do I make the On The Radar AI video from photos?
On the On The Radar AI page, add two photos: photo 1 becomes the left rapper and photo 2 the right one. You can also switch to one photo of you both. Pick the model, the resolution and 9:16, 1:1 or 16:9, press Generate, and download a 15-second MP4 a few minutes later.
There is no prompt to write. The booth, the microphone, the motion and the trend sound are built in, and the result waits in My creations if you close the tab.
Which photos work best?
Front-facing photos from the chest up, in even light, one person per photo. The clip is mostly a two-shot with moving arms, so shoulders and outfit help, and a sharp face survives the push-in close-up better than a small one. Avoid sunglasses, heavy filters and group shots with more than two faces.
For pets, use one animal per photo, full body, with its markings visible. In the video it stands on its hind legs and gestures with its front paws.
Does the video lip-sync the lyrics?
No. The performers move their mouths in rhythm and use arm and hand gestures, but it is not an exact lip-sync of the words. The "679" sound is added to the finished clip after the model renders the picture, so the audio is always the real trend sound.
If a platform mutes copyrighted audio on your post, add the sound again from that platform's own library.
Can I use it with my best friend, partner or pets?
Yes, all of those work, and two pets works too. The clip always has exactly two performers. If you only have one person, upload the same photo twice and you appear as identical twins, or use two different pets, or you and your dog.
Photos of celebrities, public figures, the original performers or minors are not accepted, and users must be 18 or older.
What does it cost, and is there a free version?
There is no free generation. A 15-second clip is 13 credits on the Standard model at 720p or 7 credits at 480p, and better models cost more. Credit packs start at $6.99 for 10 credits and never expire, and plans start at $29.90 a month. A render that fails, times out or is blocked returns its credits automatically.
Check the pricing page for the current packs before you buy.
Do I need to label it as AI when I post?
Yes, turn on the AI-generated label on TikTok, Instagram or YouTube. The clip is a made-up performance by people who never stood in that booth, and the label keeps your post within platform rules. videosi is independent and is not affiliated with On The Radar, Fetty Wap, Monty, TikTok or CapCut.
Other booth-style formats on videosi, such as Hotel Lobby AI and Tiny Desk AI, follow the same labeling advice.
The short version
Pick two photos, let the booth and the beat come built in, and post the 15-second clip with the AI label on. Everything else, from the cut timing to the sound, is already handled on the On The Radar AI page.
