DeepSeek V3 was recently launched and stands out as a powerful open-source model that delivers top-tier performance. Meanwhile, Cline (formerly Claude Dev) offers a fully open source and free AI-assisted coding workflow. With the Requesty Router you can finally use Deepseek v3 with Cline!

The benefit of using a Router like Requesty is that you can use 50+ models with tools like Cline with just a single API key. This post explores how using DeepSeek V3 and Cline together can streamline your development, simplify cost management, and boost overall productivity.

Why DeepSeek V3?

DeepSeek V3 is an advanced open-source AI model featuring:

• MoE Architecture: Efficient Mixture-of-Experts design, activating only the relevant “experts” per token to save resources.

• Multi-head Latent Attention (MLA): Compresses attention mechanisms, reducing memory usage while maintaining top performance.

• Auxiliary-Loss-Free Load Balancing: A novel load-balancing approach that boosts efficiency with minimal overhead.

• Multi-token Prediction Objective: Enables faster, more contextually coherent text generation.

These innovations help DeepSeek V3 score impressively across benchmarks—reaching 87%+ on MMLU and GSM8K—and maintain a 128k-token context window at up to 90 tokens/sec generation speed. Despite its massive 671 billion parameters, only ~37B are activated per token, keeping hardware demands surprisingly practical.

Why Use Cline with DeepSeek V3?

Cline brings an agentic coding approach to your editor and CLI, supercharging your workflow by:

1. Managing Multiple Models: Route tasks to DeepSeek V3 (or any other model) on the fly with a single key through platforms like Requesty Router.

2. Cost Tracking & Insights: Monitor your token usage and expenses in real time, switching providers or models when one becomes too pricey or goes down.

3. One-Stop Setup: No more juggling multiple API keys; just configure Cline with your Requesty Router key, and tap into 50+ models seamlessly.

4. Command & File Control: Approve each file diff, run terminal commands, and see real-time feedback. Cline’s agentic capabilities allow it to fix issues on its own—while you remain in the loop.

5. Browser Interaction: For web projects, Cline can auto-launch a browser, run tests, capture screenshots, and fix visual or runtime bugs interactively.

Getting Started with Cline

1. Install Cline:

   • VS Marketplace – Search “Cline” and install (github link)

2. Configure Your Router:

   • Sign up for Requesty Router (or any OpenAI-compatible endpoint)

   • Obtain a single API key for multi-model routing

   • Paste it into Cline’s configuration

3. Choose DeepSeek V3:

   • In your Cline settings, set DeepSeek V3 as your primary or fallback model

   • Cline will route queries accordingly and let you track usage

4. Start Coding:

   • Open the command palette (CMD/CTRL + Shift + P) and run Cline: Open In New Tab

   • Provide instructions, add screenshots/files, or let Cline read your code to start building or debugging

   • Cline can spin up a dev server, run tests, fix errors, and route to DeepSeek V3 or other models automatically

Real-World Benefits

• Cost Savings: Deepseek V3 has an amazing performance and is currently about 3-5x cheaper than frontier closed-source models.

• Resilience: If a provider experiences downtime, easily switch to another in seconds. No code changes needed—just choose a different model.

• Performance Boost: DeepSeek V3’s optimized architecture handles large-scale tasks without bogging down your system.

• Collaboration & Innovation: Teams can quickly prototype, test, and refine AI solutions with minimal overhead and clearer cost visibility.

Conclusion

Combining the raw power of DeepSeek V3 with the flexibility and agentic capabilities of Cline can significantly enhance your AI-driven projects. By leveraging Requesty Router for multi-model routing, you eliminate the hassle of multiple API keys, gain robust cost-tracking features, and ensure uninterrupted access to best-in-class LLMs. Whether you’re building a new application or improving an existing service, Cline and DeepSeek V3 offer a future-ready toolkit to help you deliver AI solutions faster, cheaper, and more reliably.
