xAI, the startup led by Elon Musk that raised $6 billion in December, has a new AI model that it claims is better than AI created by DeepSeek and ChatGPT-maker OpenAI.

In a live-streamed event on X on Monday that has been viewed over six million times at the time of writing, Musk and three xAI engineers revealed Grok 3, the startup’s latest AI model. They claimed Grok 3 had higher scores on math, science, and coding benchmark tests than OpenAI’s GPT-4o, DeepSeek’s V3, and Google’s Gemini AI.

They also said Grok 3 was a step up in sheer power from xAI’s previous model Grok 2, released in August. The latest version has more than 10 times the computational power of Grok 2, greater accuracy, and a bigger capacity for large datasets.

“The word Grok [means] to fully and profoundly understand something,” Musk said on the livestream, noting that the word came from the 1961 novel “Stranger in a Strange Land” by American author Robert Heinlein. He added later in the livestream that “if you’re using Grok 3, you may notice improvements almost every day because we’re continuously improving the model.”

xAI engineers demonstrated how Grok 3 could be used to create code for an animated 3D plot of a spacecraft launch that started on Earth, landed on Mars, and came back to Earth.

The engineers also asked Grok to combine two games, Tetris and Bejeweled, into one game. The result, which the engineers played on the livestream, was similar to Tetris with shapes inching down the screen but had the rules of Bejeweled with multicolored blocks that disappeared if there were three in a row.

Musk said that any AI could find examples of Tetris or Bejeweled online and duplicate them, but Grok 3 took it one step further.

“What’s interesting here is it [Grok 3] achieved a creative solution combining two games that actually works and is a good game,” Musk noted. “We’re seeing the beginnings of creativity.”

The researchers said they only trained Grok 3’s reasoning abilities on math problems and competitive coding problems, but they observed that Grok 3 could apply what it learned to a variety of use cases, including reasoning through making games.

xAI isn’t the only major AI startup to release advanced AI this year. Last month, OpenAI released the o3-mini, its most cost-effective yet powerful model yet, while DeepSeek came out with R1, a disruptive AI model with cutting-edge performance on a less than $6 million budget.

Grok 3 is currently available for Premium+ X subscribers paying $22 a month.

The Early Retiree’s Guide to Funding Retirement Accounts

When it comes to saving for retirement, knowing which account to fund first is like knowing which steps to take when climbing a mountain. You want to reach the summit with enough oxygen (money) and energy (tax efficiency) to enjoy the view. For those aiming to retire early, funding retirement accounts in the right order and amount takes a bit more strategy.

Over the years, I’ve contributed to just about every retirement account out there—401(k), Roth IRA, SEP IRA, Solo 401(k), HSA, and good old taxable brokerage accounts. After retiring in 2012, I’ve had over a decade to keep funding these various retirement accounts to different degrees. A lot of what you can and want to contribute will depend on your income pre and post retirement.

So if you’re trying to figure out the best order to fund your retirement accounts so you can retire eary, let me walk you through what I believe is the optimal approach—one that minimizes taxes, boosts long-term returns, and gives you flexibility to live your best life in retirement.

Table of Contents

The Ideal Order And Amount To Fund Your Retirement Accounts

To start, the main difference between a traditional retiree and an early retiree is simply the age of retirement. Traditional retirees typically stop working after age 60, while early retirees aim to do so before 60. As a result, early retirees need to accumulate enough capital and passive income to bridge the gap until they can access tax-advantaged retirement funds without penalty.

With that in mind, let’s walk through the ideal order to fund your retirement accounts if you want to retire early.

Step 1: Contribute to Your 401(k) Up to the Employer Match

Let’s start with the golden rule: never leave free money on the table.

Back when I was working in finance, my employer offered a 100% match on 401(k) contributions up to $4,000 for new employees. At the time, I was grinding hard in my 20s, working 60+ hours a week, and the idea of “free money” felt like a myth. But when I ran the numbers, I was pumped.

If you earn $80,000 and contribute 10% of your salary ($8,000), and your employer chips in ($4,000), you’re getting $12,000 invested each year. Over 30 years at an 8% return, that’s nearly $1.55 million vs. $1.06 million without the match.

Now that it’s been 26 years since I first contributed to a type of 401(k), I can clearly see the powerful effects of compounding. Accumulating your first million is the hardest, not the easiest, as I wrote in a previous post. But once you get there, your 10th million and every million after that comes much easier during normal times.

Step 2: Max Out Your HSA (If You Have a High Deductible Plan)

The Health Savings Account (HSA) is the only account that offers a triple tax benefit: tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses. The maximum contribution for 2025 is $4,300.

I wish I had started maxing out my HSA in my 20s and 30s, while paying for medical expenses out of pocket and letting the account grow. Had I done that, I’d likely have over $100,000 in additional tax-efficient retirement savings today. But back then, I didn’t fully understand my health insurance options, I just went with the default. Don’t make the same mistake. Ask your employer about all available health insurance plans and whether you’re eligible for an HSA.

That said, HSAs are only available if you’re on a high deductible health plan (HDHP). Make sure you have enough cash flow to cover surprise expenses, or this strategy could backfire. But if you’re healthy and can handle the risk, an HSA is a retirement powerhouse.

Step 3: Fund a Roth IRA

Once you’ve got your HSA sorted, it’s time to look at IRAs.

I wasn’t a fan of Roth IRAs until after I left work and had minimal income. But in hindsight, I could have contributed to a Roth IRA in my early years, which would have helped diversify my retirement portfolio.

When you withdraw from your 401(k), the IRS treats the withdrawals as ordinary income, not capital gains—which are typically taxed at a lower rate. This was one of my financial blind spots. I used to assume all investments would be taxed as capital gains. But with 401(k) contributions made pre-tax, your entire 401(k) balance ends up being one giant pot of tax-deferred income.

If you’re just starting your career and fall within the 24% federal marginal income tax bracket or lower, contributing to a Roth IRA makes a lot of sense. You contribute with after-tax dollars, your investments grow tax-free, and you can withdraw the money tax-free in retirement. Plus, there are no Required Minimum Distributions (RMDs), which provides valuable flexibility down the road.

2025 Tax brackets — 2025 federal income tax brackets

Here are the latest Roth IRA income limits for 2025:

Single filers: You can make a full Roth IRA contribution if your income is below $150,000.
Married couples filing jointly: You can make a full contribution if your joint income is below $236,000.

If your income exceeds the limit to contribute directly to a Roth IRA, you can consider a Backdoor Roth IRA. That said, I believe the breakeven point for Roth contributions is around a 24%-27% marginal tax rate. If you’re in a 30%+ tax bracket, contributing heavily to a Roth IRA may not be as worthwhile. Instead, consider converting or contributing during years of low or no income.

The key is to choose based on your current tax situation. If you’re in a high-tax state and high income bracket, a Traditional IRA might provide more immediate tax relief. If you’re early in your career or retired with lower income, the Roth could be your best friend.

Ultimately, you want to maximize tax-free income in retirement. One of the best ways to do so is with a Roth IRA.

Step 4: Max Out the Rest of Your 401(k)

After you’ve handled the match, the HSA, and your IRA, go back and fill up the rest of your 401(k). The employee maximum contribution limit for 2025 is $23,500. The limit will likely increase every two years by $500 – $1,000.

Although potentially painful in the beginning, you will get accustomed to living on less and always maxing your 401(k) out. I treated my 401(k) contributions as a necessary expense, which made contributing much easier. That “sacrifice” has compounded into hundreds of thousands of extra dollars in retirement accounts.

Here’s my 401(k) savings guide by age if you want to see whether you’re on track. Based on my guide, I believe everyone who contributes at least $5,000 annually to their 401(k) and receives and employer match will become 401(k) millionaires by 60.

Step 5: Mega Backdoor Roth (If Your Employer Allows It)

This one’s not for everyone, but if your employer allows after-tax contributions to your 401(k) and in-plan Roth conversions, you’ve got yourself another way to diversify your retirement funds.

With the Mega Backdoor Roth IRA, you can potentially contribute up to $70,000 (in 2025) into your 401(k) and then convert it to a Roth. This is a huge opportunity for high earners to build more tax-free retirement wealth.

Here’s the logic behind doing a Mega Backdoor Roth IRA that I didn’t fully grasp when I was younger, mainly due to my dislike of paying taxes. If you’re going to invest using after-tax money in a taxable brokerage account anyway, you might as well funnel as much of that after-tax money as possible into a Roth IRA, where you can enjoy the tax benefits.

Again, Roth IRA investments grow tax-free and can also be withdrawn tax-free. It’s a no-brainer and something I regret not taking advantage of earlier in my life.

Just keep in mind that not all employers offer this option, so check with your HR department or plan administrator to see if it’s available.

Step 6: Invest Aggressively in a Taxable Brokerage Account

If you want to retire early, funding your taxable brokerage account is key. It is far more important than any other retirement account.

While there are no tax advantages, a taxable brokerage account is the most flexible investment vehicle. There are no income limits, no contribution caps, and no early withdrawal penalties. As an early retiree, it’s the dividend income and principal from your taxable brokerage account that you can tap to fund your lifestyle.

Your 401(k) and IRAs are great, but they’re locked up until age 59.5—unless you go through a Roth conversion ladder or use 72(t) distributions, which are more advanced strategies. But I don’t recommend withdrawing early from your retirement funds if you don’t have to. If you want the freedom to walk away from work early, you need to focus on building your taxable portfolio.

As a target, aim to build your taxable portfolio to be 3X larger than your pre-tax retirement accounts by the time you want to retire. In other words, max out your 401(k) contributions first, then invest the same amount in your taxable brokerage account. As you earn more and get closer to retirement, strive to invest 2X (or more) of your 401(k) employee maximum into your taxable brokerage account.

This strategy helped me generate enough passive income to live off my investments in 2012 and focus on what I love.

Step 7: Earn Supplemental Income During And After Work

The final step for aspiring early retirees is to generate side income during work and after work. However, make sure you don’t violate your employee terms of agreement with your employer with your side hustle. Definitely don’t work on your side hustle during normal work hours. If you do, you will be warned, and might lose your job.

If you are a freelancer, you can open a Keogh 401(k) plan (also known as a Solo 401(k) or self-employed 401(k)) and contribute freelance income to it even if you already participate in a regular 401(k) through your employer. But you can only contribute a combined total of the maximum employee contribution for the year, e.g. $13,500 from as an employee, and $10,000 as a freelancer.

However, as a freelancer, you can also contribute as the employer to your Solo 401(k). Specifically, you’re allowed to make an employer contribution of up to 25% of your net self-employment income, in addition to your employee contribution.

The higher your net profit, the larger your employer contribution—up to a maximum of $46,500 for 2025. Combined with the employee contribution limit of $23,500, the total Solo 401(k) contribution limit for 2025 is $70,000.

Alternatively, you might find yourself in a dual-employment situation where one employer offers a 401(k) and the other provides a SEP-IRA. In this case, you could potentially contribute even more to pre-tax retirement accounts—assuming you and your employers earn enough to hit the limits.

Wonderful Retirement Benefits of Earning Side Income

The ability to contribute as both an employee and an employer can significantly boost your retirement savings. If your side business becomes increasingly profitable, you can also invest more into a taxable brokerage account. To max out the 2025 employer 401(k) contribution limit of $46,500, you’d need to earn a net profit of $186,000 ($46,500 ÷ 25%).

Best of all, a side hustle can provide a fun and meaningful purpose after early retirement. For me, being able to write on Financial Samurai and connect with readers over the years has been incredibly fulfilling. I can play sports all day.

In fact, during the two years leading up to retirement, I found myself more excited to wake up early and write posts and read comments than I was to go to my day job. So when the time came, the opportunity to focus on Financial Samurai with complete autonomy was simply too good to pass up.

Step 8: Negotiate Your Own Pension Through a Severance Package

Your final step to retiring early is negotiating your own pension package—in the form of a severance. If you’re planning to leave the workforce anyway, you might as well try. There’s no downside. Sadly, fewer than 15% of employers offer pensions today. That’s why you have to fight to build your own.

Too many employees either fear confrontation or mistakenly believe their employer would never offer them a severance for voluntarily leaving. These beliefs often stem from a lack of knowledge and emotional intelligence—specifically, the ability to see the situation from the employer’s perspective.

For example, if you’re a mediocre employee, your employer might want to let you go, but they’re stuck. Firing someone without proper documentation could expose them to legal risk. So instead, they have to initiate a performance improvement plan (PIP) that can take six months to a year.

On the flip side, if you’re a top performer, your employer will be reluctant to lose you. But if you offer to stay on during the transition and help train your replacement without disrupting productivity, they may reward your goodwill with a severance.

Our Two Severance Packages Were The Ultimate Catalysts To Retire Early

My own severance in 2012 covered five to six years of living expenses, essentially a mini pension that gave me the courage to live life on my own terms. Worst case, I could’ve gone back to work if things didn’t pan out.

My wife’s severance in 2015 gave her two years of financial runway. Even better, she returned to her old firm as a freelancer at a 60% pay bump with less stress and more flexibility. Less than a year later, we had our son, and she’s never gone back to work.

So please, for the love of all that’s good in this world—if you plan to retire early, try to negotiate a severance. You have more leverage than you think. Pick up a copy of How To Engineer Your Layoff to learn how.

A Simple Retirement Savings Framework To Keep In Mind

Max out tax-advantaged accounts = security after 60
Build taxable accounts for greater than your tax-advantaged accounts = freedom before 60

Your goal should be to take full advantage of all the tax-efficient retirement accounts available to you. If you don’t, you’re leaving money on the table that rightfully belongs to you. Thanks to hedonic adaptation—which works both ways—you’ll quickly get accustomed to maxing out your tax-advantaged retirement accounts.

Beyond that, your ultimate goal is to build your taxable investment portfolio to the point of maximum discomfort. If your monthly contributions to your taxable accounts still feel comfortable, you’re probably not contributing enough.

If you truly want to retire before 60, you must keep pushing your retirement contributions to the limit. Make it a game each month to see how much more you can save. If you’re still alive and kicking the next month, contribute even more.

Ultimately, if you can achieve a 50% savings rate after maxing out your tax-advantaged accounts, early retirement becomes a matter of when, not if.

Additional Tips For Optimizing Retirement Contributions

Watch fees. Stick with low-cost index funds from Vanguard, Schwab, or iShares. Avoid anything with an expense ratio over 0.25% unless you know exactly what you’re getting.
Keep it simple. As your wealth grows, so does the complexity. I’ve found it helpful to consolidate accounts under fewer institutions for better service and ease of tracking.
Stick to your strategy. Avoid emotional investing. Even though I invest in individual stocks, I keep ~70% of my public equities in index funds.

If you want to take your retirement planning to the next level, check out Boldin, a retirement-focused tool I’ve following and using since 2016.

It’s cheaper than hiring a financial advisor and gives you tools like Roth conversion calculators, real estate integration, and a holistic view of your portfolio. It has a free retirement planner for all to use. For an even more powerful option, its PlannerPlus version is just $120/year, and in my opinion, worth every penny if you’re serious about retiring well.

What I like about Boldin is that it doesn’t just focus on stocks and bonds—it also includes real estate, which makes up a significant portion of my net worth, as well as many Americans’. Conducting a comprehensive analysis of your entire net worth is essential for proper retirement planning.

Diversify Into Real Estate With Fundrise

If you want to diversify into real estate without the hassle of tenants and maintenance issues, check out Fundrise.

I’ve personally invested over $300,000 with Fundrise, a platform that gives you passive exposure to private real estate deals. They focus on Sunbelt markets where population and rent growth are strong, thanks to the rise of remote work.

What I like is that Fundrise combines the stability of bonds with the potential upside of equities, especially for those of us looking for diversification outside of the public markets. During times of chaos and distress, hard assets like real estate tend to outperform.

Finally, if you want more insights like this delivered straight to your inbox, make sure to subscribe to the Financial Samurai newsletter—over 60,000 people already have. My goal is to help you reach financial freedom sooner rather than later.

There’s no one-size-fits-all answer to retirement planning, but there is an optimal path depending on your income, goals, and lifestyle. There is on piece of advice relevant to everybody: Aggressively fund your retirement accounts while you still have the energy. Your future self will thank you.

3 Unseen Advantages of Mentoring Other Entrepreneurs

1744826462 mentorship valuable growth tool as entrepreneur 0425 g 466166970

Opinions expressed by Entrepreneur contributors are their own.

I didn’t start my business on my own. Sure, I’m the only founder, and I conceived the ideas that my company, Jotform, is built around.

But it’s also true that I would not be where I am today without the mentors I looked to for advice and guidance. Some of the rules I credit with Jotform’s success — for example, that I hire only when I’ve got a year’s salary already in the bank — were lifted directly from other founders who showed me the way.

I’ve always believed mentors are indispensable for anyone looking to start a business. But I’ve also come to realize that mentoring others is equally important and can help your business in surprising ways. Here’s how.

You discover new ways of thinking

One of the worst things you can do as a founder is surround yourself with people who think the same way you do. That’s one of the reasons I mentor other founders — I’m constantly surprised by how much I learn just by talking to them.

I’ve been building my own products for two decades, but that doesn’t mean I know everything. I’m constantly learning — I dedicate time each day to reading blogs and listening to podcasts to ensure I’m keeping up with what’s going on in my industry. Still, talking to my mentees about how they’re using tools like AI gives me a fresh perspective I can’t get from consuming media alone. By helping them think through how to integrate new technology into their products, I’m thinking through how I can apply those lessons, too.

Being a mentor also requires me to constantly reevaluate my own beliefs. In general, my knowledge has accumulated over years of hard-earned experience. Even so, the process of explaining why I think how I do is incredibly beneficial, either to reinforce those beliefs or challenge me to update them.

You can grow your own star performers

Everyone wants to hire a superstar. But I’ve always preferred to create them by promoting them from within. Mentoring employees within your organization provides a crucial opportunity to get to know their future aspirations, grow their confidence and help them feel more engaged with the company’s mission.

At Jotform, we call our new-hire mentorship program The New Grad Training Program. Basically, we hire people fresh out of school who show lots of promise but lack hands-on experience. They start out by doing support tasks, which range from quality assurance testing to user feedback analysis to answering customer support questions. One day per week, these new hires work with a mentor who can show them the ropes of a given department — maybe they’ll attend meetings with a data analyst or shadow a JavaScript developer. Every six months, participants can interview for the position they want. This program is a great way to develop raw talent and turn our new hires into top performers.

It’s tempting to wonder what happens if you spend time mentoring an employee, only to have them leave for a shinier opportunity elsewhere. But this is short-term thinking: Studies show that internal hires are not only high performers, they’re also more likely to stay with the organization for the long haul, while high-performing external hires are more likely to leave. My own experience confirms this: At Jotform, our annual churn rate is only 5%.

And anyway, as Henry Ford put it, “The only thing worse than training your employees and having them leave is not training them and having them stay.”

You can pay it forward

Many of the world’s most accomplished people are quick to note that they wouldn’t be where they are without the support of their mentors. Richard Branson, for example, already had experience as an entrepreneur under his belt when he founded Virgin Atlantic. That didn’t stop him from enlisting the help of Sir Freddie Laker, the founder of the low-cost airline model, for support. “I have always been a huge believer in the inestimable value good mentoring can contribute to any nascent business,” Branson has said.

Even for someone as well-regarded as Branson, success doesn’t happen in a vacuum. I know mine didn’t. That’s part of why mentoring is important to me — I want others to not only learn, but also feel like they’re not on their journey alone. There are few forces as powerful as having someone believe in you, which also leads to a deeper sense of belonging. According to Gartner, “Belonging is a key component of inclusion. When employees are truly included, they perceive that the organization cares for them as individuals — their authentic selves.”

Everyone needs a mentor. However, I firmly believe that mentoring others is equally important. Mentoring gives you the chance to learn new things and challenge your beliefs; it also builds relationships with employees who will often grow into top performers. But most importantly, it lets us reach out through the darkness and offer light to someone who needs it, allowing them to chart their own success.
