DeepSeek Harness introduced Creator Mode, a feature that converts a user’s concept into a plugin ready to use, with demonstrations spanning a design workspace, a sandbox game and a 3D large language model visualization.

The examples ranged from a design workspace and sandbox game to a 3D visualization of large language models. DeepSeek had previously optimized its V4.1-Flash model for Harness.
