• OpenAI has launched Deep Research, a new ChatGPT tool that automates multi-step internet research.
• The agentic AI tool generates "expert-level" reports and is available to Pro users.
• The launch comes as competition heats up for OpenAI from China's DeepSeek and domestic AI rivals.

OpenAI has launched Deep Research, a tool for automating complex multi-step internet research, as the company continues rolling out new products in the face of competition from Chinese startup DeepSeek.

In a Sunday blog post, OpenAI said Deep Research can operate independently to gather information from the internet to meet a user's research needs, completing tasks in "tens of minutes that would take a human many hours."

The AI agent, which is available for Pro users paying $200 a month, is aimed at professionals in finance, science, policy, and engineering.

Unlike other ChatGPT tools, Deep Research operates independently for five to 30 minutes, adjusting its approach in real time as it gathers information.

Deep Research is powered by a fine-tuned version of OpenAI's o3 reasoning model. The tool autonomously browses the internet, pulls data from multiple sources, and produces fully cited reports, OpenAI said. Mark Chen, OpenAI's chief research officer, called it "something that an analyst or an expert in a field might produce."

According to OpenAI, Deep Research has already achieved a new high score of 26.6% on "Humanity's Last Exam," an AI benchmark of expert-level questions, beating GPT-4's 3.3% score. However, OpenAI cautions the model can still "hallucinate" incorrect facts and can struggle to distinguish between rumor and fact.

In an X post on Sunday, OpenAI CEO Sam Altman encouraged users to "try it on your hardest work task that can be solved just by using the internet and see what happens."

On Friday, OpenAI launched o3-mini, a cost-efficient reasoning AI model. The two OpenAI launches come just days after Altman said his company would deliver "much better models" and move more quickly in response to the release of DeepSeek's R1 model.

DeepSeek shook the tech industry and Wall Street last month with a model that appears to match the capabilities of those from OpenAI but seemingly at a lower cost.

Last month, OpenAI rolled out its Operator AI agent, while in December it launched the text-to-video model Sora to the public.

• As a reporter covering longevity and health, I'm skeptical of new products or fads.
• As I've met researchers and doctors around the world, I've picked up a few solid tips.
• Here are my seven favorite longevity tools, including foods and supplements.

As I've spent the past few years reporting on the rise of healthy aging and longevity research worldwide, I've seen the full spectrum of antiaging hacks. Some people spend thousands of dollars on supplements, others go to posh clinics for private, highly tailored services.

None of this is for me. Instead, I've picked up a few simple, cheap longevity habits.

Hearing researchers, doctors, and nutritionists lay out their arguments for why certain activities, foods, and pills were good for my long-term health, I eventually incorporated a few research-backed changes into my routine.

Here are my seven favorite daily longevity tips.

I eat more nuts and seeds than I used to

Nuts and seeds are great sources of protein, fiber, vitamins, minerals, and "healthy" fats. In short, it's all the good stuff that our ultra-processed diets often lack.

At home, I regularly stock different nuts and seeds. I keep a bag of ground flaxseed in the freezer to sprinkle over yogurt, oatmeal, and salads. I also ensure I have chia seeds — a staple for the breakfast balls I often prep in the summertime. And I like having pumpkin seeds around for a midday snack or sprinkled into dinner.

There's one kind of nut in my cupboard that deserves a special shoutout: the walnut.

Walnuts have the highest omega-3 concentration of any nut, which is a big reason Loma Linda cardiologist Gary Fraser puts them on his morning cereal, and why leading nut nutrition expert Joan Sabaté puts them in his daily longevity smoothie. I enjoy walnuts in Greek yogurt or on a lunchtime salad.

I've upped my leafy green intake

Green leaves are rich in nutrients like magnesium, iron, and nitrogen, and they help with digestion and gut health. Greens have also consistently been linked to better long-term brain health and cognition.

Dr. Dean Sherzai, half of the husband-and-wife team known as "The Brain Docs," says if you want to pick out one thing to improve your longevity, "just add green."

Sherzai recommends getting two servings of greens into your diet a day. When I'm doing my grocery shopping, I always add a bag of greens to the haul, whether it's arugula, spinach, or a spring mix.

Tracking my sleep has made some healthy habits stick

I've become one of those people who track their sleep and try to improve their sleep "hygiene" accordingly.

It started in 2024 when I attended a longevity conference in Singapore. It seemed like everyone there was tracking something with a smartwatch or ring. The experts doing some of the most cutting-edge research on how to help people stay fit and sharp into old age were tracking the quality of their sleep.

After a few weeks of using my own smart ring, I started to appreciate the daily insights.

The ring notices, for example, when I drink a beer right before bedtime. That's when my REM sleep (the memory-storing kind) decreases and my nighttime temperature goes up.

Sleep tracking has encouraged me to drink more herbal tea before bed, take more baths in the evenings, and be gentler to myself when I'm premenstrual. All of these changes have added up to slightly better daily sleep scores, as the quality of my sleep has trended upward.

I've committed to more strength training

Any longevity expert worth their salt will tell you the best longevity treatment we have right now is exercise. Some of the most promising research into longevity drugs aims to mimic the many positive effects of exercise.

I used to only do half of the job, though. I loved cardio training and hated weightlifting. My wake-up call came when I suffered a stress fracture from running too hard, too fast, without prioritizing cross-training.

Building muscle through strength training as we age is good for bone health, pain management, and fat burning. In recent years, I've started adding more squats, lunges, and deadlifts into my routine. These are not just helping me get stronger, they're also improving mobility and making me less likely to get injured in the years to come.

A little less butter, a little more olive oil

I've started replacing some of the butter and seed oil in my life with olive oil. This is less about butter being "bad" (though there are plenty of nutrition experts who'd tell you it's not the best choice) and more about the health benefits of olive oil.

Extra virgin olive oil (EVOO) is rich in plant compounds called polyphenols, which are great for brain health, heart health, and reducing inflammation.

Nutrition expert Dr. Artemis Simopoulos recommends mixing olive oil 1:1 with butter for a healthier spread on toast. I haven't tried that yet, but I do sometimes replace butter for 100% EVOO on my toast, and I also sub out prepackaged salads and dressings for greens and olive oil.

Berries have become a near-daily treat

Over the past two years I've upped my daily berry intake, simply due to learning more about their health benefits. Berries are so rich in chemical compounds that they're like power fuel for our cells. Plus, they're better for digestion and gut health than anything sweet I might pick out of a vending machine.

I try to stock at least one to two kinds of berries in the fridge when they're in season, including blueberries, raspberries, and blackberries.

I started taking a supplement. It's not a multivitamin.

Supplements aren't magic pills, but as the name suggests they can help supplement what a person's diet or lifestyle isn't covering. While nutraceutical supplement companies in the US don't have to abide by the same rigorous standards as pharmaceutical drug companies, there are third-party supplement testing outfits that certify some brands.

In longevity circles, people tend to subscribe to a highly personalized version of supplementation. Often, they'll use blood tests and other "biomarkers" like cholesterol, blood pressure, and genetic testing to come up with a daily pill strategy.

About a year ago, on the recommendation of the Miora longevity clinic at Life Time Fitness, I did some bloodwork and started taking magnesium. It's a mineral that most Americans don't get enough of.

The magnesium supplement I buy sets me back about 28 cents per day. It is United States Pharmacopeia (USP) verified, meaning I can be reasonably confident that what's advertised on the label is in the bottle.

I got another blood test recently, and I'm no longer deficient in magnesium. I can't say the difference is obvious, but I have noticed marginal benefits for my muscle relaxation, sleep, and digestion.

• Roboforce raised $10 million in funding to make an AI robotic workforce.
• The startup, founded in 2023, develops robots for manufacturing and outdoor tasks.
• The funding will be used to expand the team, scale robot development, and launch pilot projects.

Robotics startup Roboforce has raised $10 million in an early-stage funding round led by Nobel laureate economist Myron Scholes. Gary Rieschel, who previously spearheaded Softbank's U.S. venture capital group, and Carnegie Mellon University, the alma mater of Roboforce co-founders Leo Ma and Calvin Zhou, also participated in the round.

The Milpitas, Calif.-based startup, which launched in 2023, makes AI-powered robots that carry out manufacturing tasks. The company's robots use artificial intelligence to move themselves and perform duties that require fine motor skills, like screwing in nuts and bolts, with one millimeter of accuracy, Ma told Business Insider.

The robots are also capable of working on physical projects in tough outdoor conditions, like installing solar centers in deserts, he said. They are controlled by an AI model, developed in-house at Roboforce, and some human intervention, though the company intends for the robots to reach full autonomy.

The 15-person company will use the funding to double the size of its team, scale its robot development, and roll out pilot projects with early customers. Currently, Roboforce has a fleet of under ten robots and hopes to reach double digits this year. Veeral Hardev, who runs business development, said the robots will be leased to customers through a subscription model.

Ma previously co-founded and led engineering at Cyngn, an autonomous industrial vehicle company that went public in October 2021. "Building AI robotics is all I do," Ma said. "My heart is in building AI robotics."

Ma, whose parents work in manufacturing, has been interested in automating production since childhood. Over the past decade, he has visited over 200 factories to study industrial automation. "The most tedious, demanding, repetitive, and dangerous work—we really shouldn't have to have a human do it," Ma said.

Ma and Roboforce's co-founder and vice president of engineering, Calvin Zhou, met while they were studying computer science at Carnegie Mellon. Zhou previously worked at Cruise, a self-driving robotaxi subsidiary of General Motors.

A handful of other companies are also developing robots with human-like capabilities. Elon Musk unveiled his robot, Optimus, at Tesla's Robotaxi Day in October 2024. Figure, which raised a $70 million Series A in 2023, builds robots that can complete general tasks autonomously. And Sanctuary AI, another labor market-focused robot startup, is on the market for more funding, The Logic reported on Tuesday.

Here's an exclusive look at the pitch deck Roboforce used to raise $10 million.

• We bought a fixer-upper in Canada while living in Australia, then moved our family across the world.
• Living in active construction for years was much more destabilizing than I ever imagined.
• My husband and I spent double our budget, missed time with our kids, and almost lost each other.

In 2017, we were living in Australia with our daughters and planning our move to Canada when I found my dream house on the internet.

From our home in Brisbane, I video-called and emailed a real-estate agent in Toronto, doing my best to juggle our 15-hour time difference.

Within days, I'd signed an online contract to buy the 1913 fixer-upper without ever setting foot in the house or the neighborhood.

My husband and I thought we could handle it, as we'd both lived in a few different countries and had worked with builders to renovate our Brisbane home years earlier.

However, the reality of our situation was far from what I had imagined.

The house needed more work than expected

When we bought the house, it had been divided into four apartments, so we agreed we'd live in it for a year or so while we drew up renovation plans.

However, as soon as our family moved in, we found that the house needed urgent repairs, including fixing its crumbling foundation and replacing its dangerous knob-and-tube wiring.

My husband, an engineer, decided we had to start work right away, and I didn't say no. In an attempt to cut costs, we hired the first person who said they could save us money and get the work done while we lived in the house.

As my husband commuted to his clean, quiet office for work each day, I tried to write and edit from home. Renovations, on top of the international move, were grueling.

No amount of plastic taped over doors kept the dust out of my hair, my nose, or the rest of the house. I dealt with bathroom floods and burst pipes while juggling being the sole parent and project manager since my husband had to travel for work.

My daughters, ages 9 and 11, missed their friends and our Brisbane home, and so did I.

Builders and the pandemic pushed me to a breaking point

By 2020, we had only finished a quarter of the house, and I finally convinced my husband we should move out during remodel. Before we could, though, our area went into lockdown amid the COVID-19 pandemic.

Living in renovations during the pandemic exacerbated every problem we already had. We were overwhelmed by decisions and financial pressures, and we were far away from friends in a city we didn't know.

Our daughters wrestled with severe mental-health issues, and family conversations spiraled into quarrels and angry silence.

During one late-night argument, my husband collapsed onto the kitchen floor. I should've taken it as a sign we all needed to step back, but I didn't. I became my worst self, and I hated the house.

I reminded myself constantly that we were lucky to even own a home, but it didn't help my panic attacks. After a particularly severe crisis, my doctor prescribed me medication for anxiety.

Years later, we're happy with our home — but the path to get here wasn't glamorous

All in all, it took us five years, over a dozen tradespeople, and two separate contractors to finish the house. We spent more than $1.4 million Canadian dollars (about $973,000.00), which was double our original budget.

It's hard to say if the renovations were worth all of the struggles. What I do know is that we now have a beautiful home and a new perspective.

Looking back, we realized our family took on far too much.

Our daughters were displaced by the move and destabilized by living with builders constantly in our home. And, by spending so much time working on the house, we missed precious growing-up time with them.

During these renovations, I also struggled to feel like an equal in my relationship. By letting my husband (an engineer and the main earner) make the decisions, I put too much pressure on him — and I was angry at myself for not speaking up.

After 20 years of marriage, we're finally talking about what we've learned and what we want our partnership to look like moving forward. I'm becoming more assertive, building my self-confidence, and prioritizing my mental health.

Above all, my husband and I are looking forward to never renovating again.
