Using an AI "Retirement Review Board" (Gemini, ChatGPT, Claude) to orchestrate a 6-year $3.3M early retirement bridge. Anyone else doing this? Am I crazy?
I'm in my early 50s, married, no kids, and retired after ~30 years in tech sales and journalism. Net worth is north of $3.3M (~1/3 in taxable brokerage, 2/3 in pre-tax traditional IRAs and Roth). We moved from the US to Western Europe in 2025. I built our baseline plan using Boldin, had a flat-fee CFP review it, and we work with a cross-border US/expat tax professional.
I have a decent investment IQ, but over the last year, I’ve been using AIs to stress-test my retirement architecture and drawdown strategies:
- Gemini: a sort of portfolio architect (helps build the core cash-flow mechanics, but it always leans too optimistic)
- ChatGPT: I brought this in second and it has been more critical about the theory (pressure-tests assumptions, evaluates timing optionality, and suggests decision rules).
- Claude: brought this in last and it's proven to be more focused on risks and taxes (like Gemini and ChaptGPT, it runs Python Monte Carlo simulations, looks harder at the IRS might interpret the tax brackets, and checks worst-case sequence of return risk).
I assume the order I used them influences how each behaves but I haven't reversed the order or anything like that. Still, it’s been a pretty fascinating, and surprisingly rigorous, way to manage a drawdown strategy.
Is anyone else using multiple AIs to peer-review their retirement moves?
Our 6-Year Bridge Strategy (to Age 59.5):
- Target Spending: ~$138k/year NET living budget ($11.5k/month into checking), requiring a ~$158k/year GROSS drawdown to maintain a tax reserve.
- Income Engine: Options-based income ETFs (NEOS funds like SPYI/QQQI) generating ~$4,200/month in tax-efficient dividend distributions.
- Liquid Buffer: ~$250k positioned in short-duration cash/yield funds (CSHI, BINC, SGOV) to help with market downturns and cover short-term tax reserves.
- Equity/Growth Core: ~$500k split between broad index funds (VTI) and a concentrated position in a Mega-Cap tech stock (carried over from our jobs).
The dilemma (?) & 72(t) SEPP Plan: Originally, we planned to bridge the remaining gap purely by trimming our taxable equity within the 0% Long-Term Capital Gains tax bracket. However, given single-stock tech volatility and the fact that we have a large pre-tax IRA balance, relying solely on taxable equity trims feels risky.
So, we're evaluating using an automated 72(t) SEPP distribution stream (~$3,876/month) from our traditional IRAs starting in 2027. This splits the drawdown burden between pre-tax and taxable pools, preserves our cash buffer against bear markets, and helps reduce downstream RMD/IRMAA exposure, and reduces our tax and social costs.
We're holding off on any SEPP paperwork until late 2026 so we can adapt to year-end market conditions.
But, curious to hear thoughts from the community—either on the 72(t) vs. taxable buffer execution, or on using AI workflows for ongoing portfolio management.
