DeepSeek Open Sources dsh Framework: Plugin-Based Agent Orchestration
卡尔的AI沃茨 · wechat · 2026-08-15
DeepSeek has open-sourced its Agent framework, DeepSeekHarness (dsh), which garnered 20k stars on GitHub within an hour. Its core feature is the "everything is a plugin" architecture based on Cordis, allowing users to replace even the main control loop. It supports both WebUI and CLI, launchable with a single command.
The framework offers four preset modes:
- Standard Mode: Full-featured for general tasks.
- PTC Mode: Compiles multi-step operations into a program for one-time execution, ideal for long workflows and large data tasks.
- Minimalist Mode: Terminal + editor only, for benchmarking.
- Creative Mode: Supports runtime checks and self-written code, capable of generating new Agent presets (high privilege).
Real-world tests show that in PTC mode, the Agent can autonomously write scripts and perform global sampling for website performance analysis, rather than relying solely on local tests. The author posits that Agent capability equals Model × Harness, arguing that dsh significantly unlocks model potential, particularly enhancing the performance of lower-cost models like v4-flash.
