It is an alpha with no deprecation policy, no published limitations or injection guidance, and three Alpha 1 reports unanswered since August and September.\n\n## Before you call either\n\n### Hume EVI (Empathic Voice Interface)\n\n1. Create a config with a voice first, EVI 3 has no default\n2. Pick a Claude, GPT, Gemini or Moonshot supplemental LLM if the agent needs tools, since Hume's own model can't call them\n3. Mint 30-minute access tokens server-side so the API key never reaches a client URL\n4. Turn on 'Do not retain data' and 'Do not use for training' at app.hume.ai before sensitive calls\n5. Reconnect with the chat group ID before the 30-minute session cap, and on E0700 close an open chat before starting another\n\n### Pipecat PhoneLLM\n\n1. Send `temperature: 0` on every call. The repositories' generation_config.json samples by default, and Max's sets temperature 1.0\n2. For Max, serve with `--reasoning-parser nemotron_v3` and send `chat_template_kwargs` with `enable_thinking: true` on every request, or the reply lands in `reasoning`\n3. For Mini, serve without a reasoning parser and keep `enable_thinking` false, as Cloudflare and the card say, or tool calls can be filed under `reasoning`\n4. Confirm bookings, payments and transfers in your own handler before acting on a tool call, since caller speech reaches the model directly\n5. Pin the model ID including `alpha-2`. Daily states no notice period, and a later alpha may replace it\n\n## Questions\n\n### Which is better for AI agents, Hume EVI (Empathic Voice Interface) or Pipecat PhoneLLM?\n\nPipecat PhoneLLM scores 58.7 (C) on agent readiness against Hume EVI (Empathic Voice Interface)'s 56.7 (C), and leads in 2 of 7 scored categories.
