I'm using AI gateway + unified billing, generally it works without giving credentials but only aig authorization headers. But weirdly, openai/gpt-5.2-2025-12-11 and anthropic/claude-opus-4-5-20251101 models gives 401 error, is there a good reason why? Maybe it's because they are recent models and cloudflare forgot to allowlist them?
