Two Minute Papers — 'DeepSeek's New AI System Shouldn't Be Possible'
Two Minute Papers covers DeepSeek Harness, the MIT-licensed agent framework where every capability is a plugin. The episode description links the Harness page and the Cordis plugin-system paper the framework is built on.
Two Minute Papers walks through DeepSeek Harness, the open agent framework that treats models, tools and sandboxes as swappable plugins.
What is it?
'DeepSeek's New AI System Shouldn't Be Possible' is the August 26 Two Minute Papers episode about DeepSeek Harness. The description points at two sources: the Harness page on deepseek.com and the Cordis paper repository on GitHub. DeepSeek Harness is already in the feed as a release from August 13, 2026.
How does it work?
The episode keeps the channel's short-explainer format and draws on DeepSeek's own documentation. Harness is built on the Cordis plugin system and runs on two stated rules — everything is a plugin, and every run is traceable — so models, tools, skills, sessions, sandboxes, storage, loops, scheduling and the UI can each be swapped out. Session logs record every model interaction for later inspection and replay.
Why does it matter?
Most agent frameworks make you edit core source code to change how the agent behaves. The plugin-first design in DeepSeek Harness means a team can replace the model or the sandbox without forking the project, and the recorded sessions give a way to see what an agent actually did. Harness is free and open source under the MIT license, and is still in developer preview.
