Voice agents that remember.

The Voice Memory Layer (VML) for Grok Voice. .fafm 🐘🎙️ LiveKit enabled.

> Two profiles, one .fafm format. This is the voice profile (the Voice > Memory Layer). For the knowledge profile — typed, cross-linked agent memory — > see claude-fafm-sdk.

The Fast⚡️AF memory setup

pip install grok-faf-voice

from grok_faf_voice import VoiceAgent

VoiceAgent().run()

That's it. First run, your agent gets a namepoint — your @handle for FAF memory. Auto-generated free, no email needed. Want a branded handle tied to your email (or your X username)? Claim one anytime at mcpaas.live/voice/setup — one per valid email address.

---

What you need

• Python 3.10+
• An XAI_API_KEY — get one at x.ai/api

That's it. Namepoint and Voice key are provisioned for you.

Run it:

python my_bot.py console

console mode talks locally — no LiveKit cloud needed. Deploy to LiveKit later via python my_bot.py start.

---

How it works

• The agent listens via xAI realtime — five built-in voices: Ara · Eve · Leo · Rex · Sal
• Every session opens already remembering what was etched in past ones
• At session end, new memories consolidate silently
• Cross-session, cross-device, cross-model — your namepoint is the address

Voice swappable, memory permanent. ElevenLabs and Hume land in upcoming releases.

Custom Voices

xAI shipped Custom Voices on 2026-05-01. We shipped support 48h later.

from grok_faf_voice import CustomVoiceClient, VoiceAgent

# Clone a voice from a 90-120s WAV sample
cv = CustomVoiceClient()  # uses $XAI_API_KEY
voice = cv.create_voice("sample.wav", name="My Clone", language="en")

# Use the cloned voice in your agent — same two-line shape
VoiceAgent(voice=voice["voice_id"]).run()

Custom voice IDs (8-char lowercase alphanumeric, e.g. nlbqfwie) flow through VoiceAgent(voice=...) unchanged. The 30 free voices via console.x.ai work too — paste the voice_id and go.

Local souls (.fafm files)

Read and write souls straight off disk — no MCPaaS, no API key. Great for inspection, tests, backups, and loading souls written by other FAF-family tools (cross-vendor interop).

from grok_faf_voice import FAFMemory

# Load a .fafm soul from disk (any profile — voice or knowledge)
mem = FAFMemory.from_file("soul.fafm")
body   = await mem.get()                  # the soul body
recall = await mem.recall_for_prompt()    # ready for the prompt

# Write it back out (byte-identical roundtrip)
await mem.to_file("backup.fafm")

# Typed views — no manual parsing (v0.3.1)
mem.profile    # "voice" | "knowledge"
mem.facts      # parsed list of memory facts
mem.index      # top-level index (knowledge profile)

.fafm is the IANA-registered FAF Memory format (application/vnd.fafm+yaml). Validate documents against the published JSON Schema.
