DeepSeek quietly ships Harness GUI desktop app with PTC orchestration and plugin architecture
solyarisoftware · x · 2026-09-30
- DeepSeek quietly released a desktop Harness GUI for Windows/Mac: runtime prepackaged (no npx/Node/pnpm), lowering the barrier for non-developers.
- Full agent visibility: Tool Calls, tokens, runtime, file diffs, subagents, and task status are all inspectable in the GUI.
- PTC Mode orchestrates multiple tools into a program executed in one pass — fewer round trips, fewer tokens, more stable on complex tasks.
- Everything is a plugin: terminal, Office, browser, computer use, subagents, agent teams, even the GUI itself are converging on a Plugin Host architecture, turning Harness from an agent framework into an extensible agent workbench.
- Existing Harness plugins migrate directly; official account login supported.
