DeepClaude – Claude Code agent loop with DeepSeek V4 Pro, 17x cheaper (github.com)

DeepSeek has launched DeepClaude, an innovative integration that enables the Claude Code autonomous coding agent to utilize DeepSeek V4 Pro as its backend, dramatically reducing costs to 17 times less than the original Anthropic model. This groundbreaking approach allows developers to leverage a similar user experience while benefiting from DeepSeek’s advanced capabilities, which have achieved a notable 96.4% score on LiveCodeBench. Users can easily set it up using a simple API key and enjoy autonomous coding functions such as file editing, bash execution, and multi-step tool loops—all at a fraction of the price. The significance of DeepClaude for the AI/ML community lies in its cost-effectiveness and enhanced functionality. With DeepSeek's automatic context caching, the cost for subsequent requests plummets to just $0.004/M, making it an attractive option for both light and heavy usage scenarios. Moreover, DeepClaude retains the versatility of the Claude Code environment while enabling users to switch back to Anthropic's models for complex reasoning tasks. This flexibility, combined with substantial cost savings—up to 90% for light users—positions DeepClaude as a powerful tool for developers seeking efficient and affordable AI-driven coding solutions.
