How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track GPT-Live-1, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
GPT-Live-1 is a proprietary model. No explicit reasoning mode is documented in this profile.
Available in the OpenAI API as gpt-live-1 since September 10, 2026 through v1/live/sessions over WebRTC, WebSockets, and SIP telephony, after first shipping in ChatGPT Voice. Audio and text in, audio and text out; reasoning and tool calls are delegated to a Responses model or a client-side agent and billed separately.
GPT-Live-1 is a display-only full-duplex voice model that listens and speaks at the same time and delegates reasoning and tool use to a backend model. OpenAI’s API launch evaluation remains separate from BenchLM’s weighted text-model ranking.
The profile has no source-displayable benchmark row yet.

Frequently asked questions
How does GPT-Live-1 perform overall in AI benchmarks?
GPT-Live-1 does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.
Does GPT-Live-1 have full benchmark coverage on BenchLM?
No. GPT-Live-1 currently has 0 source-displayable rows across 434 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of GPT-Live-1?
GPT-Live-1's provider has not published a context-window limit for this exact model. The profile leaves the value unavailable instead of borrowing a number from an earlier family member or a third-party route. Maximum output length is tracked separately when the provider documents it.
