Inspect detailed evidence, sources and research gaps

September 2026 remains the historical baseline. A new research date does not mean a feature launched that day. Unknown after research and not researched are separate states.

Official documentation establishes what the supplier documents. No paid calls, independent product benchmarks or compliance audits were performed in this research pass. Coverage measures research work, never product quality.

Price structure

Per minute

V3.3 evidence review · Contract-defined minute billing; no public numeric quote

per-minuteVerified Yes · 2026-09-28

Sales-led per-minute contract rate, not a public numerical rate.

Human fallback

Unknown — no established fallback mode

UnknownUnknown after research · 2026-09-28

No individually verified capability establishes this selection. Conditional support and vendor claims do not satisfy Strict Must-have.

Documented transfer is not a staffed human service. Verify who answers, when they answer and what happens if they do not.

Try it yourself

Unknown — no independently checked public demo entry is attached.

External signals

No dated external signal in this record. Missing evidence is not a negative review.

Underlying model context: the documented stack above does not establish an exact benchmark checkpoint or its deployed settings. Public model results cannot become a PolyAI score.

Append-only price history

Every capture leaves a trace.

A new check creates a new snapshot. Deltas appear only for the same currency, unit, model and scope.
