GPT-Realtime mini questions
How much does the GPT-Realtime mini API cost?
$0.60 per million input tokens and $2.40 per million output tokens, with cached input at $0.06. The estimator on this page turns that into a monthly bill for your own workload.
Does GPT-Realtime mini support tool calling?
Not through the standard tools parameter. For an agent that calls your APIs, pick a model from the alternatives below that does.
Is GPT-Realtime mini open source?
No. OpenAI serves it through an API only, so you cannot download the weights or host it yourself.
When was GPT-Realtime mini released?
Oct 10, 2025.
Catalog data from models.dev (MIT licensed), refreshed daily, last on Oct 15, 2026. The summary is written from these facts.
Building on GPT-Realtime mini?
I test your real tasks on it and the two closest alternatives, then ship the agent on whichever wins on cost and accuracy.
