DeepSeek has released a desktop application for its open-source agent harness, a runtime that enables AI models to perform tasks like reading files, running commands, and maintaining plans. The v0.2 preview includes built-in tools for office work and coding, plugin management capabilities, file review features, and support for document work with charts and slides. The harness is not locked to DeepSeek models and can work with third-party providers through OpenAI-compatible endpoints, treating every layer including the agent loop as replaceable plugins. This matters because it provides developers with an open-source alternative to proprietary agent systems, available as a developer preview with expected breaking changes ahead.
