DeepSeek drops enhanced coding agent with aim to rival Anthropic

DeepSeek's "Super-agent" is an open-source prototype designed to proactively observe developer group chats, identify coding problems, and propose solutions without a direct summons. The DeepSeek Harness team stated on WeChat that the agent's objective is to "take as little human attention as possible, and give as much value as possible," indicating a focus on highly autonomous AI assistance in software development.

This agent's development is attributed to DeepSeek's Harness team, which was formed in 2026 to build AI agents for coding services, specifically targeting offerings from US laboratories such as Anthropic. The term "harness" describes the software scaffolding that enhances large language models, enabling AI agents to manage more complex tasks, a methodology also utilized by Anthropic and other developers.

The launch occurs amidst an intense competition between Chinese and US firms to develop advanced and affordable AI tools. While the initial AI race was driven by chatbots, the focus has increasingly shifted to the lucrative market for AI agents that automate tasks for developers and business professionals. DeepSeek's recent fundraising, securing approximately 100 billion yuan (S$19.2 billion) before its initial public offering, provides substantial capital for its competition with established players like Anthropic and OpenAI.
