What each one is
DeepSeek
DeepSeek Harness (dsh) is an open-source agent harness from DeepSeek AI, built so that nearly every part is a plugin. It runs on Cordis, a plugin framework the README links to, and can be started as a local Web UI. The README describes it as being in developer preview, so the interface and APIs may change.
Qwen Chat
Alibaba's chat interface for its Qwen model family, covering text, coding, image and video generation. Capable models at no cost. Data-handling terms and jurisdiction are worth checking for business use.
