DeepSeek Building Code Harness – Coding Agent Tool at 1/100th Cost

DeepSeek is explicitly moving from model provider to coding platform, forming a Code Harness team and developing a Desktop Agent product. DeepSeek-TUI (Claude Code competitor) achieves 80.6% SWE-bench, 7x cost reduction vs Claude Opus, MCP support. Leverages DeepSeek's extreme cost advantage (1/100th of competitors). Job postings and roadmap signal serious intent. Could become cheap backend for agentic coding SaaS wrappers.
