Cloud HTTP API for **ChatGPT-class models** — chat completions, embeddings, images, audio, and assistants-style tool use.
When to use
Production apps, quick prototypes, embeddings for RAG, when you want managed scaling.
When not to
Strict data residency requirements without approved enterprise terms — check your org's policy first.
Example
client.chat.completions.create(
model="gpt-4o-mini",
messages=[{"role": "user", "content": "Hello!"}],
)
