[Arvin Sun @ArvinSun]

Multimodal AI. At text-model speed.

Traini is now processing real-time pet multimodal signals in <400ms:

Vocalization + vision + behavior + emotion + movement + physiological signals + context + memory.

@Transsion is bringing @Traini’s PEBI AI directly into its smartphones.

Meet Woof Talk — a native AI feature that translates dogs’ vocalizations, emotions, and intentions into human language in real time. No extra device. Just talk to your dog through your phone. @Apple @Samsung

Me hearing "We have 500k users rushing in": 😎 Let's go!
Me looking at the dashboard 5 seconds later: 🤦‍♂️ Modern art. The good news: We went viral.
The bad news: So did my blood pressure.

Traini named among 2026’s Top 30 AI Hardware Innovations.

AI is no longer just software.
2026 is the year AI becomes physical.

An interesting phenomenon on highways in China:

You often see cars driving very slowly — but staying in the fast lane.

In the U.S., this happens far less often.

Why?

Because many Chinese drivers believe the fast lane is safer.

We recently developed a 3D Pet Emotion Model, powered by Traini’s proprietary Instant Emotion Vector (IEV).

If emotion represents the inner dimension of a pet, then time and location represent its external world.
