Google's latency-led live model is the default candidate for most real-time voice-agent pilots. Its published per-minute audio rate is only a component price, so HubAI withholds a score until interruption quality, accepted-call completion, language coverage, recovery and complete cost are tested independently.
Voice-agent teams now have a latency-led default and a deeper-reasoning option at published API rates, but complete resolved-call cost and quality still require a same-flow test.
Google launch announcement ↗Gemini 3.8 Live is designed for low-latency voice and vision agents where interruption handling, live context and background tool calls matter. HubAI treats it as a workflow purchase rather than a novelty: the relevant question is whether it produces an acceptable result repeatedly, with controls your team can understand and a cost that remains predictable after the trial ends.
Low-latency voice and vision agents where interruption handling, live context and background tool calls matter
approved minutes of natural, correctly pronounced audio with documented voice rights
Known foundation-model errors, occasional slowness and timeouts still apply
Use one approved 60-second script containing names, numbers and difficult pronunciation.
Bring one representative input
Run the same job three times

Run a fixed set of representative calls against both Gemini routes and one alternative. Record task completion, interruption recovery, language and accent errors, tool failures, timeout recovery, escalation time and every provider, telephony and infrastructure charge.
HubAI will publish a score only after the same representative tasks have been run against current alternatives. Vendor benchmarks are not treated as an editorial rating.
The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.
Pricing checked for editorial use on 4 September 2026. Confirm live price, VAT, region, usage rights and cancellation terms with the vendor before purchase.
Model your own usage. HubAI separates subscription cost from retries and human review—without pretending a headline plan price tells the whole story.

Gemini 3.8 Live is best suited to low-latency voice and vision agents where interruption handling, live context and background tool calls matter. HubAI's current verdict is: Google's latency-led live model is the default candidate for most real-time voice-agent pilots. Its published per-minute audio rate is only a component price, so HubAI withholds a score until interruption quality, accepted-call completion, language coverage, recovery and complete cost are tested independently.
A free Gemini API tier is listed; quotas, account eligibility and product-surface availability vary. Check the official product page before buying because allowances, regions and eligibility can change.
$0.005/min audio input and $0.018/min audio output at the published standard API rate; text, image/video, grounding and the surrounding call stack may add cost. The useful comparison is total cost per accepted result, including retries, limits and human correction—not the advertised entry price alone.
