NAVER D2SF has put roughly KRW 3 billion into TraceWeave, a startup that built Phase‑TITAN – a new AI architecture that keeps memory use constant even as it processes long text. The company says its 1‑billion‑parameter model needs only 0.04 GB for a 1‑million‑token context, compared with tens of gigabytes for a standard Transformer. TraceWeave demonstrated the model running on a smartphone CPU without any cloud calls and completed a paid pilot with an autonomous‑driving unit of a global car maker.

## The facts

- Investment amount: approx. KRW 3 billion (seed round led by Mirae Asset Capital)
- Phase‑TITAN 1B model uses 0.04 GB for 1 M‑token context versus tens of GB for a comparable Transformer

## Why it matters

Device makers could add sophisticated AI assistants to phones, drones or glasses without needing cloud connectivity, lowering latency and protecting user data.
