What each platform ran, and what we saw

Gemini Live

Strength
Second-highest repetition score at 4.78/5 across 174 scored calls.
What can be improved
One rerun had no latency evidence and scored 0/5 for both task outcome and tool accuracy.
Speech-to-speech setup
  • reasoning: high
  • hybrid VAD

Smallest AI

Strength
94.31% task completion across all 246 calls, and 62.71% pass³ on the Appointment suite (37 of 59 scenarios).
What can be improved
Atoms tool parameters cannot be arrays, so Medicare list arguments arrive as comma-separated text; its tool accuracy reads that text as a list. With the standard check it scores 45.12% pass³.
