Evalathon - Break the Voice Agent

The Voice Agent Evalathon (July 6–15, 2026) is a fully virtual, competitive challenge where participants are tasked with hunting for intentional flaws inside a purpose-built voice AI agent running on the Telnyx platform, hosted and evaluated through Okareo.

Over a five-day window (July 7–11), contestants use Okareo's agent simulation tools to systematically probe the agent across four dimensions — Reasoning, Execution, Performance, and Stability (the REPS Rubric) — documenting findings with severity ratings and reproduction steps. Prizes range from $400 in agent credits for Bronze up to a $3,500 Ai4 Las Vegas conference pass plus $1,000 in credits for Gold, with winners announced at a live virtual roundtable on July 15.

The event is powered by a coalition of Okareo, Telnyx, AITHORS, and Agent Builders Breakfast, with Ai4 2026 as the grand prize sponsor.
