Zeus is a fully agentic harness for voice AI: an AI agent that builds, tests and tunes your voice agents for you. Zeus configures agents on the ThunderPhone voice AI stack, which combines multiple models at once to achieve higher accuracy (99.4% on Big Bench Audio) and lower price (from 2¢/min) than competitors based on 3-step STT-LLM-TTS pipelines or single speech-to-speech models. Create an agent by talking to Zeus, or import one from Vapi, Retell, Bland or ElevenLabs.

TranslateMyCall is back — rebuilt from scratch on ThunderPhone's production voice-AI pipeline, now faster and more accurate than the 2024 original. Call (228) 888-8666 from any phone — no app, no account — and an AI interpreter joins the line. Merge it into a call so each side hears their own language, or put it on speakerphone for in-person interpreting. 47 languages officially supported; others may work as well! Free for a limited time.
