Access notes

Proxy may be needed

If multiple provider keys become painful, compare official providers, API gateways, and alternatives.

Recommended path

1

Start from the main OpenAI profile and confirm whether it fits your task.

2

Create an API key after signup and use the $5 first.

3

Run one or two real tasks before paying or switching providers.

4

If access is unstable, compare relay options or local alternatives.

Production decision checks

Production budget

OpenAI free credits are for validation. Before launch, record cost per 1K requests, retry-adjusted cost, and a monthly spend cap.

Compatibility check

If you already use the OpenAI SDK, verify OpenAI base URL, model names, streaming, tool calling, and JSON mode before migration.

Fallback rule

Keep one similar provider or OpenLLMAPI route ready so credit exhaustion, regional access issues, or model deprecations do not break users.

Source trail

Save this source snapshot plus the official console state so future quota, pricing, and rate-limit changes can be audited.
