DeepSeek to form a 'Code Harness' development team, taking on Claude Code and Codex

DeepSeek is reportedly building a ‘code harness’ team to take on Anthropic’s Claude Code and OpenAI’s Codex.

The company is hiring product managers and R&D engineers in Beijing for the new agentic coding tool effort.

DeepSeek V4 is already available in Claude Code, and its pricing is far below top-tier rival models.

The move signals DeepSeek’s push beyond low-cost models into the developer tooling market, raising competition in AI coding tools.
