I watched an AI fool 48% of humans on a video call — here's what it means

I saw a wild test this week: Tavus released Griffin on Oct 1, an AI model that holds live video calls. Old AI avatars work like walkie-talkies — listen, transcribe, think, then speak. Griffin is full-duplex: it watches your face and listens to your tone while it talks, pauses when interrupted, nods and says "mm-hm" at the right moments.

In Tavus's own blind test, 54 people each had a 1-minute video call with it; 26 of them (48%) thought they'd spoken to a real person. The company's older system fooled just 1 in 41. Caveat: it's their own study, small sample, one-minute calls — still, the direction is clear.

Funnily enough, you can try today's AI assistants yourself: Meta's Muse is running an invite program — new users enter an invite code in Settings within 48 hours of signing up and both sides get 1 billion tokens. Limited uses, first come first served. Code: SW5HCB, https://muse.ai/join

What exactly is a "token"? An AI beginner's plain-English guide

When I first started using AI assistants, the word that confused me most was "token." Simply put, a token is the smallest unit an AI reads and writes — roughly one English word counts as a bit more than one token, and one Chinese character is about one token. Every question you ask and every answer it gives burns tokens, which is why many AI apps charge by token.

1 billion tokens sounds scary, but it lasts longer than you'd think: casual chatting, research, and document writing burn maybe a few hundred thousand a day — 1 billion covers an ordinary user for years.

Side note: Meta's new AI assistant Muse is running an invite program right now. New users who redeem an invite code in Settings within 48 hours of signing up get 1 billion tokens each — for both sides, credited directly as usable quota. Codes are limited-use, first come first served.

I Tried Meta's Muse AI Agent — Here's How to Get 1 Billion Free Tokens

I spent the weekend playing with Muse, Meta's new personal AI agent, and honestly it's the most useful AI assistant I've tried in a while. It can browse the web, handle emails, do research, plan things — actual agent stuff, not just chat.

The interesting part: new users can get 1 billion free tokens with an invite code. Here's the quick version of how it went for me:

Sign up at https://muse.ai/join
After signing up, go to Settings → Redeem invite code within 48 hours (this is the step most people miss — the code expires)
Enter an invite code. Mine is SW5HCB — we both get the token bonus when you use it.

A few things I learned:

The 48-hour window is real. Don't sign up and forget to redeem.
The free tokens are a usage balance, not unlimited everything — but 1B is generous for trying it out.
It works best when you give it real tasks: "plan my trip", "research this topic and summarize", "draft this email".

If you've been curious about AI agents, this is a pretty low-risk way to try one. Happy to answer questions in the comments.
