AI Gateway is transparent on model ids
Cloudflare AI Gateway does not validate model names; upstream does
AI Gateway routes by provider/prefix and forwards model strings. "Invalid model ID" is usually upstream or unknown provider prefix.
Custom providers: base URL + slug; model path appended. Related: project-anyrouter, tech-llm-gateway-quota-as-retryable.
