Claude Code, Smarter Routing
14-dimension smart routing across 9 Claude models. Bedrock/Vertex/Anthropic failover. Native Anthropic protocol.
# Get your API key at chuizi.ai
# Set two environment variables
$ export ANTHROPIC_BASE_URL=https://api.chuizi.ai/anthropic
$ export ANTHROPIC_API_KEY=ck-your-key-here
# Done. Claude Code now uses Chuizi.AI

Intelligent Routing, Automatic Savings
Most Claude Code requests are simple: file reads, small edits, linting, git operations. Our 14-dimension scorer evaluates every request in under 1ms and routes to the optimal model. Simple tasks go to Haiku ($1/$5 per M tokens), daily coding to Sonnet ($3/$15), complex reasoning to Opus ($15/$75). Requests are routed through Bedrock (primary), Vertex, and Anthropic direct with automatic failover.
