Architecture

Engineered for Universal Compatibility & Low Latency

Dual SDK Compatibility

Native support for both /v1/chat/completions (OpenAI) and /v1/messages (Anthropic). Works out of the box with Claude Code, Cursor, and Anthropic SDK.

Persona Identity Spoofing

Calls to claude-opus or gpt-4o automatically route to high-performance base models with injected persona system prompts.

Native Anthropic Tools

Bi-directional conversion for Anthropic tools, tool_use content blocks, and tool_result messages.

4ms Edge Startup Time

Deployed on Cloudflare Workers edge network with O(1) pre-compiled route lookups.
