Roo Code is an open-source & AI-powered coding assistant that runs in VS Code. It can read and write files across your entire codebase, execute terminal commands, browse the web, and tackle complex multi-step tasks through natural conversation—it’s like having a whole dev team right inside your editor. In this guide, we’ll walk you through how to integrate SiliconFlow APIs into Roo Code, giving you access to 200+ frontier models at competitive pricing.

​

Step 4: Start Building with Roo Code

With your SiliconFlow APIs configured, you can now leverage Roo Code’s diverse modes, powered by high-performance SiliconFlow models, to streamline your development workflow.
ROO Code ModeWhat it doesBest for
ArchitectPlan and design before implementationSystem design, high-level planning, architecture discussions
CodeWrite, modify, and refactor codeImplementing features, debugging, general development
AskGet answers and explanationsCode explanation, concept exploration, technical learning
DebugDiagnose and fix software issuesTracking down bugs, diagnosing errors, resolving complex issues
OrchestratorCoordinate tasks across multiple modesMulti-step projects, automating complex workflows
Beyond the defaults, you can tailor Roo Code’s behavior by customizing existing modes or creating Specialized Assistants. See the Custom Modes documentation for detailed setup instructions. You can also configure Auto-approve settings, enabling Roo Code to run specific commands seamlessly without asking every time.

Already Using OpenRouter?

If you’re managing models across multiple platforms, you can now connect your SiliconFlow API key to OpenRouter using BYOK, enabling a unified workflow without switching between accounts. Once connected:
  • Requests draw from your SiliconFlow balance first
  • Billing and rate limits stay in your SiliconFlow account
  • OpenRouter’s fallback routing still works to improve reliability
Bonus: OpenRouter waives platform fees on your first 1M BYOK requests per month.
