Canonical Model System

Provides a unified view of model metadata (pricing, capabilities, context limits) across different LLM providers. Normalizes provider-specific model names (e.g., claude-3-5-sonnet-20241022) to canonical IDs (e.g., anthropic/claude-3.5-sonnet).

Build Canonical Models

Fetches latest model metadata from OpenRouter and validates provider mappings:

cargo run --bin build_canonical_models              # Build and check (default)
cargo run --bin build_canonical_models --no-check   # Build only, skip checker

This script performs two operations by default:

1. Builds canonical models - Fetches from OpenRouter API and updates the registry
   • Writes to: src/providers/canonical/data/canonical_models.json
2. Checks model mappings (unless --no-check is passed) - Tests provider mappings and tracks changes over time
   • Reports unmapped models
   • Compares with previous runs (like a lock file)
   • Shows changed/added/removed mappings
   • Writes to: src/providers/canonical/data/canonical_mapping_report.json

The script is located in this directory: build_canonical_models.rs
