Perplexity CEO Aravind Srinivas. Bloomberg/Getty Images Perplexity is working on an AI coding tool that builds software from start to finish. The tool has been used internally since May and is codenamed "Teammate," according to screenshots. Perplexity may launch the tool publicly, putting it in direct competition with startups like Cursor. Perplexity could be the latest entrant to the red-hot AI coding wars. The San Francisco-based AI search startup has built an internal AI coding tool that it may launch publicly later down the line, a person familiar with the matter said. For now, Perplexity has codenamed the tool "Teammate," and its engineers have been using it since May, according to screenshots obtained by Business Insider. It's unclear exactly if or when Perplexity, which was valued at $20 billion in a funding round last year, will launch the product. If it does, it would put Perplexity — originally focused on an AI-powered search engine that competes with Google — much closer to vying for supremacy with Cursor, Anthropic, and OpenAI, all of which have built widely-used AI coding products. Teammate is meant to oversee software projects from start to finish, according to an internal announcement seen by Business Insider. "It's built for long-horizon engineering work: owning projects, investigating issues, and monitoring services," the announcement reads. A Perplexity spokesperson declined to comment. Perplexity engineers have given the tool tasks such as finding bugs in internal systems, screenshots show. The AI tool is model-agnostic, meaning that it's not built on any particular chatbot, the person familiar with the matter said. Perplexity's chief technology officer, Denis Yarats, has also urged the startup's engineers to use AI for coding. A few weeks before Teammate launched internally, the executive wrote in messages viewed by Business Insider that by the end of the year or sooner, software engineers should "stop looking at code" and just use AI. Yarats also defended AI against accusations that it produces "slop," or poor-quality code. "Slop is not going to be a thing" as long as the code it generates passes quality checks, Yarats wrote.

Microsoft CEO Satya Nadella. Sven Hoppe/picture alliance via Getty Images Microsoft is offering up to 39 weeks of severance to most laid-off US employees. The company on Monday announced plans to lay off around 4,800 employees. The severance offer is similar to Microsoft's recent voluntary retirement buyout program. Microsoft is offering laid-off US employees up to 39 weeks' base pay for most US employees, according to severance offers reviewed by Business Insider. Microsoft on Monday announced plans to lay off around 4,800 employees, or 2.1% of its global workforce, confirming Business Insider's earlier report. The US severance package includes a minimum of 60 days of base pay, during which employees will remain on the payroll, up to a maximum of 39 weeks of base pay for most employees, based on seniority and tenure. Employees at internal levels 64 and below will receive one week of base pay per six months of service, and employees at levels 65 to 67 will receive two weeks of base pay per six months of service. There's a separate package for executives levels 68 and higher. The company is also offering continued regular stock vesting for six or 12 months for levels 67 and below, based on years of service, and six months of paid health insurance coverage plus an additional 12 months of optional COBRA coverage. Those terms are similar to those the company offered earlier this year in its Voluntary Retirement Program buyouts, according to a document viewed by Business Insider, except that the layoffs include shorter health insurance coverage durations. The layoffs come as Microsoft cuts costs and plans significant spending, including $190 billion in capital expenditures this year, primarily related to its AI infrastructure buildout. The cuts mostly impact the sales and Xbox gaming organizations, Microsoft chief people officer Amy Coleman wrote in an email to employees. Microsoft's Xbox division also plans to cut 20% of its workforce by the end of June. A maximum of 39 weeks of severance appears more generous than offers from some competing tech companies. Salesforce, which recently conducted layoffs, has a standard severance package of a minimum of nine weeks and a maximum of 30 weeks of base pay. Oracle offered laid-off US employees four weeks' base salary, plus one week per additional year of employment, up to 26 weeks, as severance. Meta, meanwhile, recently offered laid-off US employees a severance package including 16 weeks — or four months — in base pay, plus two weeks for every year of continuous employment. Have a tip?

If you're building something ambitious, this is a fast track to the people who can move your startup forward.
Cases have risen quickly as officials are working to identify a common source.
Maddy and Drew Olson built their own home to ensure their mortgage payments were affordable. Maddy Olson Maddy and Drew Olson wanted to own a home, but they didn't want an expensive mortgage. They bought a lot and built a house themselves in Washington, setting their budget at $209,000. Because they built the house themselves, their mortgage is less than $1,000. Maddy Olson had never tiled anything before when she set out to tile the two bathrooms in her new home. That wasn't going to stop her, though. Olson and her husband have been building their first home together, doing as much of the work as possible themselves to cut costs. Through trial and error, the Olsons pulled it off. They built their home in Washington in about 9 months, sticking to their budget so their monthly mortgage payments could be less than $1,000. Becoming homeowners has long been a goal for Maddy and Drew Olson. Maddy Olson Maddy, 27, and Drew Olson, 28, lived in a rental home when they got married in 2019, but they were already daydreaming of owning a place of their own. Their landlord even offered to sell them the rental for $249,000 at one point, a price that felt out of their budget. "We were like, 'Oh my gosh, that's so expensive,'" Olson said of the home, which sat on half an acre of land. "Now we're like, 'That would literally be a dream.'" Still, the couple, who have a 19-month-old daughter named Campbell, had a plan. The Olsons decided to save as they established their careers — Maddy is a content creator and owner of Over Ice Soda, while Drew works in commercial concrete — planning to buy a lot and build their own home to keep mortgage payments down. In 2025, the Olsons finally found a spot where they could build their family home. Maddy Olson The Olsons finally made the jump in January 2025, buying a lot for $156,000. Though the lot was smaller than they had hoped, they liked the location, as it's down the street from their cousin's home. "It wouldn't be our ideal, but it's been seven years of thinking about it," Olson added. Olson also came to like that the lot size ended up saving them money as they built out their home. "We really couldn't overspend if we wanted to," she said. "It's easy to spend a little bit more and make it beautiful without having to spend so much because there's not a lot of space to build." Budget was top of mind for the Olsons as they built their home. Maddy Olson Keeping their build budget limited was important to the Olsons, as they wanted their mortgage to be as small as possible. They set their budget at $209,000 and secured a loan for the build. The couple planned to cut costs primarily by doing as much work as they could themselves, saving money on "sweat equity." They felt confident they could accomplish their goal because Drew had some construction experience. "It was his first time doing most of the stuff in our house, but he has a general knowledge of how to use most tools," Olson said. "Most of his family is in home building." They hired professionals to handle tasks like installing the HVAC and drywall, but the Olsons said they did basically everything else. "Drew works for his parents, so he has a lot of wiggle room," Olson said. "On any slow days when there wasn't work, he'd be here working at the house." Olson also said her mom and mother-in-law were a big help with her daughter's caregiving while she worked on the home. The Olsons based their 1,400-square-foot home on a builder's designs. Maddy Olson The 1,400-square-foot design features three bedrooms and 2.5 bathrooms. Rather than working with the builder, they based their design on the builder's existing floor plans, making some small changes to customize the space for their family. "We basically used the plan except for changing minor things," Olson said. "It's such a small space that there wasn't much wiggle room, really. We could maybe cut off two feet here, add two feet there, or change a closet, but it just made sense to kind of go with what they had." They officially started building in September 202 and lived in a rental house for much of the build. They stayed with Drew's parents for the final stretch of the project. Olson wanted the home to feel sunny. Maddy Olson Olson took the lead on the house's aesthetics, saying she wanted the home to feel warm. "I like the California cottage type of vibe," she said. "People are always like, 'If you're in the Pacific Northwest, you should go with moody darker tones and deep greens,' but I get sad in the winter." Instead, she gravitated toward warmer neutrals in her design, thoughtfully adding color throughout the space. For instance, she added a wood beam to her bedroom to make it feel more dynamic. She also created a DIY penny-tile pattern in her daughter's bathroom that included colorful flowers. She complemented the flooring with butter-yellow walls, creating a bright and inviting space. "I'm obsessed with it," she said of the bathroom. Olson had to balance her taste and her budget as she designed the home. Maddy Olson Because they were working with a limited budget, Olson had to be selective with her splurges for the house. For instance, they built their kitchen cabinets themselves to save money, constructing them at home after the manufacturer mailed them. Because she didn't have to pay for installation, Olson splurged on a Botticelli Breccia Marble countertop for the island in the same room. The island cost $5,700, a price Olson found well worth it for the pop it brings to the space. "That is my prized possession in my house," she told Business Insider. She also splurged on large windows to bring natural light into the space and on her gold doorknobs. Some of Olson's favorite decor pieces were thrifted. Maddy Olson Olson shopped secondhand for her home whenever she could, often turning to Habitat for Humanity Restore and Facebook Marketplace to track down secondhand items. She found tile for her primary bathroom on Marketplace for $10 per square foot, which typically costs $40 per square foot, saving hundreds of dollars. She also tiled the bathroom backsplash herself, saving costs. Olson also found the vanity for her daughter's bathroom on Facebook Marketplace and had it professionally painted to make it feel fresh. She saved money by buying light fixtures on Amazon and affordable flooring from Floor & Decor. She also stretched her money by making sure she could reuse pieces she bought, like the leftover bathroom tile she's giving to her mom to use in the tiny home she's building. There were challenges to the build process, of course. Maddy Olson Because the Olsons had never built a home before, they didn't know when certain design decisions had to be made. For instance, they didn't know outlet locations had to be settled before drywall went up, so they weren't as intentional about where they were placed as they would have been otherwise. They also realized their house would be darker than they wanted after it was already framed, so Drew had to go back in and cut more windows to brighten the space. Later in the construction process, Olson came to the house to find her husband was nearly finished building their staircase. She had wanted a more custom look for the spindles, but didn't realize it was too late. Luckily, Drew was happy to take out the existing structure and change it for his wife. "He's an angel," Olson said. Committing to design choices was also tough. Maddy Olson Olson also said she struggled to be decisive, changing her mind after trying certain paints, light fixtures, or even tiles. A video on her TikTok page shows her removing tile from a wall, looking at it after it's been professionally painted, repainting it after she didn't like the color, then painting it again after that color didn't work either. She also told Business Insider she found herself retiling rooms repeatedly and buying light fixtures online, only to return them after she disliked how they looked. "It was worth it in the end, but I wanted to cry every day," she said. "I'm very type B and relaxed, but when it comes to my house, I feel like I ripped out tile so many times because it just didn't look right." The Olsons finally moved into their house at the end of May 2026. Maddy Olson The house is largely finished, though Olson said they are still fine-tuning details and decorating. Her daughter's room and their third bedroom aren't decorated yet, and it will take some time to get them in order. Still, they pulled off the renovation within their set budget, keeping their monthly mortgage payments under $900. Olson said it's "amazing" for her family. The Olsons hope their current home enables them to build something larger down the line. Maddy Olson The Olsons plan to live in their home for a few years, but their long-term goal is to use the money they're saving to buy a new property and build a larger home. Olson credits their self-build as the reason that the dream is feasible. "We're in a really good position now where if we found a lot tomorrow, we would be in a position that we could buy it," Olson said. "We couldn't buy it cash, but we could buy it and build a house and be able to rent this out." Read the original article on Business Insider
