GPT Realtime
Decision readingGPT Realtime is tracked, but not publicly ranked yet. Published speech or voice results from AudioAgentBench appear below. They do not produce a weighted text-model score.

Voice benchmark evidence
AudioAgentBench is an owner-defined voice evaluation. Its result stays separate from BenchLM's weighted text-model ranking.
Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

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 Realtime, 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 Realtime is a proprietary model with a 32K context window. No explicit reasoning mode is documented in this profile.
Provider-hosted access; consult the linked documentation for current availability.
GPT Realtime is tracked because it appears in audioagentbench. Voice-protocol results remain separate from BenchLM's weighted text-model ranking.
Speech or voice evidence appears above; text-model benchmark coverage remains empty.
Last updated October 29, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does GPT Realtime perform overall in AI benchmarks?
GPT Realtime has published speech or voice results in AudioAgentBench. Those results remain separate from the weighted text-model ranking, so this profile does not assign a BenchLM score or overall rank. Use the linked evaluation's metric and run conditions to compare speech systems.
Does GPT Realtime have full benchmark coverage on BenchLM?
No. GPT Realtime's speech or voice results appear in AudioAgentBench, but it has no published text-model benchmark rows. The voice evaluation does not fill the text-model coverage slots or produce an overall rank. Missing text coverage is not treated as a zero score.
What is the context window size of GPT Realtime?
GPT Realtime has a documented context window of 32K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
