I. Introduction: The Agent Dilemma

Developers, have you met Claude Code? It’s Anthropic’s powerful AI-powered coding assistant, offering a terminal interface to delegate complex programming tasks directly to the model. It's a game-changer for agent-based development.

The catch? Your agents are typically bound to one model ecosystem. If you want to leverage the speed of GPT or the unique capabilities of Gemini for your coding tasks, you’d have to rewrite your agent’s logic.

Introducing the solution: OneRouter's General Conversion Layer.

II. What OneRouter Helps You Achieve

The industry trend is clear: successful AI teams are decoupling agent logic from the underlying LLM. This is why we created the OneRouter General Conversion Layer—it's the critical infrastructure layer that breaks the model barrier for the Claude Agent SDK.

You can now run your Claude Agent SDK logic against any model in OneRouter—without changing your agent code. This flexible architecture enables you to power your Claude Code sessions with diverse underlying model engines, including:

• Gemini 3 models as the core runtime.

• GPT series models as the core runtime.

• The full series of Claude models as the native core.

This means you can instantly switch your agent's underlying intelligence just by adjusting an environment variable, achieving maximum flexibility and performance optimization.

III. The OneRouter Advantage: Simplified Deployment

OneRouter provides the Anthropic SDK compatible LLM API services that make this possible.

Instead of managing multiple vendor SDKs and API keys, OneRouter allows you to:

1. Use Your Familiar Tools: Keep using the Claude Code CLI tool, but route its requests through us.

2. Universal Authentication: Set up your OneRouter API Key once, which then authenticates all calls to Claude, GPT, or Gemini.

3. Model Flexibility: Determine which powerful model powers your terminal session simply by setting a single environment variable—no code changes required.

We've eliminated the vendor lock-in, so you can focus on shipping your agents faster.

IV. Conclusion: Ship Your Agents Faster

The market trend is clear: successful AI teams are decoupling model logic from infrastructure. OneRouter is the tool you need to ensure you can use cutting-edge frameworks like the Claude Agent SDK without the limitation of vendor lock-in. This capability is ready now. Don't let your competitors define the standards.
