DeepSeek releases Harness 0.1.5 with V4.1 Flash support, file uploads and sidebar previews DeepSeek released version 0.1.5 of DeepSeek Harness on Sept. 10, adding dedicated optimization for V4.1 Flash plus file-upload and sidebar-preview features, according to IT Home. Version 0.1.5 supports V4.1 Flash in standard, programmatic tool-calling (PTC) and minimal modes, allows system prompts to be updated while retaining the existing KV Cache, and lets users upload images and PDFs for model-assisted file reading. The update also adds workspace file-tree previews for Markdown, HTML, PDF, code and image files, standardized plugin extension points, improved long-session performance, two-way communication with child agents, and an experimental Agent Teams plugin that lets a main agent create and coordinate multiple team members but is disabled by default.
