DeepSeek R1 and Claude Code represent two distinct approaches to AI-assisted development: transparent chain-of-thought reasoning versus autonomous agentic execution. DeepSeek R1 uses a Mixture-of-Experts architecture with visible reasoning traces, costs $0.55/$2.19 per million input/output tokens, and supports self-hosting via Ollama or vLLM. Claude Code operates as a CLI agent that reads files, runs commands, edits code, and iterates autonomously, but costs $3/$15 per million tokens with no self-hosting option. Head-to-head comparisons across algorithmic challenges, multi-file refactors, and debugging show R1 excels at pedagogical transparency and budget-conscious reasoning tasks, while Claude Code dominates execution-heavy workflows like codebase-wide renames and test-run-fix loops. VS Code integration setup is covered for both tools. A hybrid workflow using R1 for planning and Claude Code for execution is recommended for teams that need both reasoning depth and autonomous implementation.
