Black Whale Emerges, DeepSeek's Second Half Begins
DeepSeek has unveiled its V4 Pro model and officially launched DeepSeek Harness, a developer-preview agent framework released as open-source under the MIT license. The article highlights that while model capabilities set the upper limit, the execution system (or "Harness") significantly determines real-world task success rates and cost efficiency, as demonstrated by tests where the same DeepSeek V4-Flash model performed differently across various harnesses.
DeepSeek Harness is built on a "Everything is a plugin" philosophy using the Cordis system, allowing developers to modularly replace or extend core components like the model, tools, and UI without modifying the core code. It emphasizes full traceability with an append-only session log and is designed for stable, long-running tasks. Notably, it supports integration with nearly 40 external LLMs, including Kimi, OpenAI, and Anthropic, positioning itself not as a fixed agent but as a customizable platform.
The release signals a strategic shift for DeepSeek from merely selling computational tokens (inference) to delivering actionable results (task completion). However, the v0.1 Harness faces challenges, including competing with established players like Claude Code, building a robust plugin ecosystem, and adapting to a potential "pay-for-result" business model. The article concludes that while both V4 Pro and Harness are early-stage with gaps to top models, DeepSeek's consistent direction is to make advanced AI capabilities affordable and operable within practical systems, with its long-term success now tied to the open-source community.
