CREDIT CARD REQUIRED. 30-day credit expiry from signup. Azure OpenAI access-request form was removed March 2026 — no longer gated. Free-tier Azure subscriptions may still fail to deploy Foundry models in some cases.

Our take
Microsoft throws $200 of Azure credit at new accounts and — as of March 2026 — the old Azure OpenAI access-request form is finally dead. Anyone with an account can deploy GPT-4o now. Catches: credit card required, 30-day clock on the credit, and free-tier subs still choke on Foundry deployments sometimes. But $200 is $200 for a serious throughput test.
