Tau3 voice tasks (airline/retail/telecom), paired with GPT-6 Astra

Accuracy · Third-party report

Test conditions and source

Vendor-reported launch benchmark; GPT-Live-1 delegates reasoning to GPT-6 Astra (medium effort) backend — this is a pipeline score, not GPT-Live-1 in isolation. Compared only against OpenAI's own prior model, not an independent/neutral arena. Published source text: OpenAI's official launch post (mirrored on community forum) states: 'Paired with GPT-6 Astra at medium reasoning effort, GPT-Live-1 completed 83.6% of Tau3 tasks on the first attempt, versus 45.7% for GPT-Realtime-2.1.'

Features and tool support

TokenBazaar’s exposed interface, not every feature advertised by the provider. “Available” describes the implemented interface, not a successful test of every input or tool.

Input through TokenBazaar

Not verified

Consult the integration documentation; no additional input formats are claimed here.

Output through TokenBazaar

Not exposed

Live voice currently has an upstream availability blocker; a catalog entry does not prove working connections.

Function-tool conversations

Not exposed

This is a dedicated media or utility endpoint, not a conversational function-tool interface.

Sources and verification

Provider specifications describe the upstream model, not a guarantee of every feature through TokenBazaar. Prices come from the enabled catalog; benchmark results belong to the exact tested model.
