Fetty Wap 679 AI: Make the Viral Rap-Duet Video
Scroll TikTok or Reels in late 2026 and you will find pairs of unexpected performers — best friends, dogs and cats, cartoon duos — trading rap verses in a dark live radio-show studio. That is the Fetty Wap 679 AI trend: an AI-powered recreation of the famous On the Radar-style “679” rap-duet performance. Our free generator makes your version from two photos; this guide covers where the trend came from, copy-paste prompts, the tools that can make it, and the copyright lines to respect.
Upload two photos (one per performer), pick a stage, click Generate. A 5-second rap-duet clip with audio, ready for TikTok in under two minutes.
What Is the Fetty Wap 679 AI Trend?
The visual reference is a live radio-show performance: two rappers standing side by side in a dim studio, each with their own microphone, trading verses over a hard-hitting beat with hyped, crowd-level energy. That two-mic duet framing is the signature the trend recreates — and it is why the format needs two subjects: you and a friend, two pets, or any unlikely pair.
In the trend, you feed one or two portrait photos into an AI video generator with a prompt that describes the scene: dark radio studio, boom-stand mics, verse trading, synchronized bounce. The model returns a clip of your subjects performing the duet. Creators then pair the clip with the trending audio in their editor — or post the AI-generated audio that tools like our generator produce, which avoids copyright issues entirely.
Variants span solo versions, pet and character swaps, slow-motion edits, and full VHS-styled broadcasts. The constant is the recognition: two subjects, two mics, one hyped duet.

How to Make Your Own 679 AI Video
Route A — our dedicated generator (fastest)
- Upload two performer photos. Open the free generator and use the default Two Photos mode — one portrait per performer — for the strongest identity lock. A single side-by-side frame works too. Only upload photos you have the rights to use.
- Pick a stage. On the Radar Live for the trend-accurate dark radio studio, or Neon Smoke Cypher / Chrome Studio / 90s VHS Broadcast for a fresh twist.
- Generate and iterate. Click Generate — the clip usually finishes in 30–90 seconds. If the bounce looks stiff, switch the stage or adjust the photos and re-run.
- Post it. Download the MP4 and publish, or add your platform’s licensed trending audio in TikTok / CapCut first. Switch the aspect ratio to 9:16 to fill the phone screen.
Route B — any image-to-video model (more control)
- Open Image to Video. Create a free account and you get starter credits to experiment with.
- Upload your portrait(s) and pick a performance-strong model — Kling 2.6, Grok Imagine Video 1.5, or Seedance 1.5 all handle stage-performance motion well. Multi-image reference support lets you feed both performers.
- Paste Prompt 1 or 4 from the library, set 9:16, choose 5–10 seconds, and generate.
- Edit and post. Cut on the beat, add the audio you licensed, and publish. Re-run with different prompts to A/B test your thumbnail frame.
