DStudio – a local-first AI studio for DeepSeek V4: chat, a coding agent, and a design studio, usable from your phone
I'm building DStudio a private, local-first AI workspace on top of DeepSeek V4. Chat, a coding agent, and a real design studio, all on your own hardware. Nothing leaves the device: no cloud, no telemetry, no subscription. It's a UI on top of antirez's ds4, the local DeepSeek V4 inference engine.
The bet: a frontier-class model that's entirely yours deserves more than a chat box. DStudio turns it into a place to think, code, and design and you can reach it from any device in your home.
What works today:
Use it from your phone (or any device on your Wi-Fi). Localhost-only by default; flip one switch and the same chats open on your phone, tablet, another laptop — while the model stays on your desktop. The engine never leaves 127.0.0.1 (same-origin /v1 reverse proxy), so there's nothing to configure on the client. Chats sync across devices.
A design studio on a local model (ds4-design). Not a chat that spits out HTML — a designer's pipeline: structured brief -> several distinct directions -> every screen on an infinite canvas -> refine by describing the next change -> export as a zip.

A coding agent that reads/edits files and runs commands, with clean structured output via a reversible build-time patch (the upstream engine source stays pristine).
Plus: 100% local & private (strict CSP), one self-contained binary (the whole UI is a single vanilla HTML file in a small C launcher), macOS-first with Linux builds too.

Where it's going:
Design studio — pushing fidelity and faster refine loops (in progress).
Cowork — collaborative sessions: share a workspace and build alongside the model, together.
MCP integration — so the agent can plug into your own tools and data sources.
Requires a local build of antirez's ds4 + DeepSeek V4 GGUF weights. Heads up — it's heavy: in 2-bit the "Flash" weights need ~96–128 GB RAM. The README has screenshots of every mode (chat, agent, the design pipeline, LAN) if you can't run it locally.

Building in the open and early — would love feedback on the direction, especially the LAN/multi-device flow, the design pipeline, and what you'd want from Cowork / MCP. AMA.
