# Sources:
#   1. Static (below) — Codex-specific models (not returned by /backend-api/models)
#   2. Dynamic          — general ChatGPT models fetched from /backend-api/codex/models

# Dynamic fetch merges with static; backend entries win for shared IDs.
# Models endpoint now requires ?client_version= query parameter.
