New in Mezzi: Upgraded AI—New Models

Last updated: April 7, 2026

We just refreshed the lineup — so if you’ve ever gotten an answer that felt off, try the same question again with the new models.

Gemini 3 is now in Mezzi ⚡️🧠

You may have heard that Google's Gemini 3 is a major leap forward. In Mezzi, you can now pick:

Gemini 3 Flash (default)

Fast + great for most portfolio questions:
Compare Nvidia vs Apple performance
What's my exposure to technology?
Give me my current asset allocation
Any tax-loss harvesting opportunities?

Gemini 3 Pro

Best when you want deeper reasoning / longer responses:
Should I consider a Roth conversion?
Draft a plan based on my accounts and goals
How would I rebalance from 90/10 to 70/30?
Growth vs value: what’s my mix?

GPT-5.2

We've also introduced GPT-5.2, replacing GPT-5.0 in Mezzi. Like Gemini 3 Pro, GPT-5.2 is also a significant upgrade over GPT-5.0.

Our early testing suggests that Gemini 3 Pro performs better than GPT-5.2, but we'd like to hear from you as well.

How we choose models

Personal finance AI has unique requirements.

It's very data-intensive. We've built Mezzi to handle complex portfolio data accurately and we continue to make it increasingly precise.

AI isn't perfect—all AI can make errors from time to time. We understand how important accuracy is. Please always check answers carefully and continue to report issues to us.
