What to know about GPT-Realtime Mini
AI-compiled from linked model documentation. This is a catalog reference, not an independent performance review. Catalog checked October 23, 2026.
Which GPT-Realtime Mini does this page describe?
GPT-Realtime Mini is a model record from OpenAI in the GPT family. Source
The recorded model identifier or checkpoint is gpt-realtime-mini-2025-12-15. Use that exact identifier when checking documentation or a provider listing. Source
How can you access GPT-Realtime Mini?
The catalog documents API access for GPT-Realtime Mini. Source
As of the catalog check, this version was marked deprecated. Source Check the linked lifecycle information before starting a new integration.
For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription.
What are GPT-Realtime Mini's context and output limits?
The documented context window is 32,000 tokens. Source
The documented maximum output is 4,096 tokens. Source
Context, input and output limits describe different constraints. Do not add the figures together to infer a larger window. Check the endpoint's accounting for conversation history, system instructions, tools, media and generated tokens; a documented maximum is not a guarantee of answer quality or a measured usable capacity.
What dates are documented for GPT-Realtime Mini?
Knowledge cutoff: October 1, 2023. Source This labels the documented knowledge boundary; it is not a promise that every earlier fact is known or correct.
Retrieval or web tools can supply newer information at run time. That does not change the model's recorded training or knowledge dates, and this record does not establish that a particular endpoint includes those tools.
What can GPT-Realtime Mini receive and generate?
Documented inputs: text, image, and audio. Source
Documented outputs: text and audio. Source
Input support and output generation are separate capabilities. Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation.
