Vivix.AI, a young startup that describes itself as building real-time interactive video models and the infrastructure to run them, has announced two models in a three-post series on its X account. The company's umbrella message was blunt: **"Content is alive."** According to Vivix, real-time interactive experiences need two things, characters that come alive and worlds you can step into, so it trained one model for each.

The announcements are the company's own; there is no independent testing or benchmarking, and everything below reflects Vivix's own descriptions and demos. The account opened in September 2025 and remains small.

## A1: full-body characters you can interrupt

Vivix describes A1 as a full-duplex, full-body model. Full-duplex (two-way) means the character keeps listening while it talks and moves, so you can jump in mid-sentence or redirect it mid-walk and, the company says, it turns around and follows your lead. Full-body means the character has arms and legs.

- Cross a room, dance, and pick things up while, Vivix says, objects keep their exact and natural form.
- Look puzzled when you change your mind, or get hurt when you turn away.
- "Characters, not just talking heads," in the company's words.

## W1: a world that never stops

Vivix-W1 is described as a streaming-native multimodal model, a world model that runs non-stop with no "start over." You shape it as it runs.

- Talk to it, tap or click the screen, or drop in a picture, and what you do changes what happens next.
- Everything stays live: characters you can interrupt and worlds you can mess with.

The W1 post included a demo video of a toy-like village scene, with a cursor stepping in as it played. Access is limited for now: Vivix says both models sit behind a private API beta at platform.vivix.ai, not open to the public. The announcements were posted on the company's account, [@VivixLabs\_HQ](https://x.com/VivixLabs%5FHQ?ref=globalfeed.ai); the A1 post links to its model page at [vivix.ai](https://vivix.ai/?ref=globalfeed.ai), and the W1 post to [vivix.ai/vivix-w1](https://vivix.ai/vivix-w1?ref=globalfeed.ai).
