NOTES ## Field notes [Grok Build](https://www.agentlist.io/systems/grok-build) X subscribers who want a frontier CLI bundled with a plan they already have — SuperGrok $30/mo is the cheapest subscription gate in the category. Caveat — Usage draws from one weekly pool shared with Grok chat, image, and voice — long runs consume it fast. No standalone CLI subscription. [Grok Voice Agent API](https://www.agentlist.io/systems/grok-voice) Teams shipping high-volume voice agents who want one vendor for the speech stack instead of stitching STT/LLM/TTS. Caveat — Younger ecosystem than the stitched-stack incumbents; telephony billed separately and voice-agent pricing is per audio minute.
