DeepSeek launches official desktop version of its AI framework

On September 25, 2026, DeepSeek AI released the official desktop version of its Harness framework, currently in developer preview with version V0.1.7-rc.2. The desktop version eliminates the need for Node.js installation, terminal access, and manual command execution, supporting Windows x64 and macOS Apple Silicon (M-series) systems. The framework, open-sourced in August 2026 under the MIT license, is written in TypeScript and features a plugin-based architecture called Cordis, enabling modular customization of AI agents. It offers three modes: Standard for general tasks, PTC for batch processing, and Creative for custom plugin development. Users are advised to back up data and monitor future releases due to potential stability and compatibility limitations in the preview version.
