Use case
GPT-5.5 streaming
streaming notes for gpt-5.5: the rate card, a worked volume, and when to send this ID. A sample of 1 million input tokens plus 200 thousand output tokens is about $2.20 on corouter (input $1.00, output $1.20).
How streaming is billed
A streamed response is still billed on input and output tokens, not on how long the socket stays open. Output for gpt-5.5 is $6.00 per million tokens.

A field you can set
A familiar chat-completions shape often sets "stream": true next to "model": "gpt-5.5". On a messages shape, follow the stream field your client actually sends.
GPT-5.5 keeps the high GPT-5.6 Sol list rate and the Code tag. Send gpt-5.5 when a workload was already qualified on that exact ID.
