Show HN: Zeus – Claude Code for AI voice agents

ThunderPhone v3 introduces Zeus, a fully agentic harness that configures, tests and tunes voice agents for a business's use case, replacing the retired Spark, Bolt and Storm pre-baked stacks with one unified architecture. ThunderPhone says its multi-model architecture, which runs multiple transcription models and combines faster and slower LLMs turn by turn, scores 99.4% on Big Bench Audio. Zeus is free for now, and ThunderPhone uses cost-plus pricing with margins from 17% to 25%.
