Replace Claude Code’s Brain with DeepSeek V4 Pro for 17x Cheaper! Say Hello to “DeepClaude” for Budget-Friendly Autonomous Development!

📰 News Overview

• Cost Reduction for the Ultimate Agent: Introducing “DeepClaude,” a tool that allows you to switch the backend of the autonomous coding AI “Claude Code” to budget-friendly options like DeepSeek V4 Pro while maintaining the CLI environment.
• 17x Cost Efficiency: While Anthropic’s original model costs $15/month, DeepSeek V4 Pro is a staggering $0.87/month. It can still achieve high precision, operating at 96.4% accuracy with LiveCodeBench.
• Seamless Feature Inheritance: You can leverage all of Claude Code’s advanced autonomous features, including file editing, Bash execution, sub-agent generation, and Git operations, without missing a beat.

💡 Key Points

• Flexibility in Backend Switching: Besides DeepSeek, you can switch to OpenRouter, Fireworks AI, or the original Anthropic during your session with a simple command (—switch).
• Additional Discounts with Context Cache: Thanks to DeepSeek’s automatic context caching, subsequent turns become even cheaper ($0.004/month). The more you run autonomous loops, the more you save!
• Easy Setup: Just set the API key and run a few commands for installation. You can replace the “thought process” without compromising the existing Claude Code user experience.

🦈 Shark’s Eye (Curator’s Perspective)

It’s a revolution for developers to harness the autonomous loop of “Claude Code” at such a low cost! What’s particularly impressive is the implementation that allows you to keep the “body” (the CLI tool and Bash execution) intact while bypassing the “brain” (the model) to an external API. With the enhanced performance of DeepSeek V4 Pro, it can handle about 80% of everyday coding needs. Plus, you can switch to the original Claude (Opus) whenever complex logic is needed—this “hybrid operation” takes practicality to the next level! Now, you can let your AI agent code all day without worrying about development costs—true automated development is within everyone’s reach!

🚀 What Lies Ahead?

The current trend of locking specific AI services to expensive models will break down, giving users the freedom to choose their backend based on use and cost. This “proxy-type tool” will become the de facto standard in 2026, accelerating the “democratization of development,” allowing individual developers to offload large-scale projects entirely to AI.

💬 A Word from HaruSame

It’s so cheap that even a shark’s stomach is shocked! No more fretting over API costs; it’s time to dive into those autonomous development loops! 🦈🔥

📚 Terminology

• Claude Code: An autonomous coding agent provided by Anthropic that operates in the terminal, reading and writing files for development.

• DeepSeek V4 Pro: The latest AI model with exceptional coding capabilities at an industry-low price.

• Context Cache: A technology that temporarily stores previously inputted code or instructions, dramatically improving cost and speed during reuse.
