DeepSeek Harness
DeepSeek Harness (dsh) is DeepSeek's open-source agent harness, released under MIT and built so that everything is a plugin, from the model adapter and the tool registry to the agent loop itself. Start it with npx @deepseek-ai/dsh web and it opens a local web UI where the agent reads and edits your workspace, runs commands, and keeps a plan, with a headless profile for one-shot jobs from the terminal. On qynio it runs on any of 700+ models rather than DeepSeek's own alone: add qynio as a custom provider and you get one key, automatic fallbacks, and a choice of region.

Run DeepSeek Harness on these models
Run DeepSeek Harness across our providers
On qynio, DeepSeek Harness can reach every provider in the catalogue. Pick where your inference runs, keep it in the EU when you need to, and use zero data retention on supported routes.
