Google’s latest AI weather model gives you no excuse to forget your umbrella
Scientists at Google DeepMind and Google Research released a new artificial intelligence model for weather forecasting today that sees our changing atmosphere more clearly and predicts its behavior more often. WeatherNext 3 is the latest wave of a sea change in meteorology brought out by deep learning techniques, and Google says it will start feeding into weather information users see in search, Google Maps, and Gemini, as well as being available to users and researchers on Google’s cloud platforms. “This is going to be the first time that some of the core variables feed and power a lot of the Google products,” Samier Merchant, a Google senior staff engineer, told TechCrunch. The new model has already proven to be the most accurate among leading contenders tested onOperational WeatherBench, a utility for comparing AI forecasts built by the startup Brightband. It looks at metrics like temperature, windspeed, and humidity. As well as beating out other deep-learning models built by Google, Microsoft, Nvidia, and the European Center for Medium-Range Weather Forecasting (ECMWF), it also beats traditional forecasts from the U.S. National Weather service and the ECMWF. Most weather forecasts come from government-owned supercomputers laboriously churning through mathematical equations written to describe the physics of weather; while these systems have become remarkably accurate, they are expensive and comparatively slow. After the ECMWF released more than half a century of weather data produced by these systems in 2018, deep learning researchers began training models that could make predictions far more quickly and with comparable accuracy to government tools. “Weather is chaotic, and so small differences really start to perturb massively…Machine learning targets the problem we are really solving, which is approximate noisy physics from incomplete information and finite compute, and so it learns patterns from a lot of data,” said Ferran Alet, a staff research scientist manager at DeepMind. Since then, model-makers have pushed on the key weaknesses of AI forecasting models: They tend to forecast over a wider area — 15 to 25 square km — than is truly useful, they’re not always great with rain, and they still depend on the formatted datasets produced by government agencies. WeatherNext 3 takes on all three challenges. On key variables, researchers told TechCrunch, it can predict down to a resolution of 5 km. Its evaluations on rain are 60% improved over WeatherNext 2, and it can now produce hourly forecasts, instead of the standard prediction every six hours. Those improvements are the result of specific choices made by the designers. WeatherNext 3 is a larger model, with 2.4 times more parameters than its predecessor, tailoring the targets for the decoder heads to give more useful answers. While most weather forecasts output as metrics averaged across a 3D grid, DeepMind researchers have already won plaudits by tuning their model to also visualize cyclone paths. This time around, the designers also trained the model to target its forecasts to specific weather data stations. This is important not only for offering more granular predictions, but also for being able to evaluate its work against specific, ground-truth data. “The idea, with a lot of AI applications, is to try to run tasks as end-to-end as possible,” Daniel Rothenberg, an atmospheric scientist at Brightband, said. “Adding a capability where this model is now also predicting, say, what Denver’s airport’s weather station is going to measure on an hourly basis, just connects that forecasting task closer to the core.” The model is able to forecast more frequently because it can ingest weather satellite data collected in real time on an hourly basis. Feeding AI models on raw empirical observations, rather than the analysis produced by weather supercomputers, promises a more accurate forecast, but it is still technically challenging to get models to work with unformatted data. Google says WeatherNext 3 is the “first” AI model to directly incorporate raw observations for a high-resolution global forecast, but the AI weather startup WindBorne says its model, WeatherMesh 6, has beenincorporating raw observationsfrom its fleet of weather balloons and other sources since late 2025. Asked about that, Google pointed out that its forecasts are higher resolution across the globe. Regardless, both models still rely on national weather datasets to perform forecasts, so more work will be required for true direct data assimilation. While LLMs get the bulk of the attention, the transformer revolution in meteorology has been just as important. European and U.S. weather agencies are already using AI models in their forecast products, and their speed and low cost promise to bring economic impact to poorer regions where the expense of high-quality sensors and supercomputers has put accurate forecasts out of reach. Bill Gatesrecently citedAI-powered weather forecasting as a crucial benefit of the technology, with better forecasts improving crop yields in developing countries. Alet, the DeepMind researcher, said that higher-resolution forecasts of wind, rain, and cloud cover will be useful to make renewable energy projects more dependable. “At the end of the day, I think Google is about providing useful information to the user, and a lot of what users are looking for has to do with the weather in some way or another,” Alet said.

Ollie is betting its focus on privacy can help it win the AI assistant race
For an AI assistant to become truly useful, it first has to know a lot about you.Ollie, a personal assistant for everyday life, is betting that doesn’t mean you have to hand over all your data and sacrifice your privacy in the process. While some enterprise-focused AI assistants have data privacy protections in place, Ollie is among the first mainstream, family-focused AI to achieve SOC 2 compliance — a framework that allows a company to demonstrate, through an independent audit, that it has formal controls in place to protect customer data and operate its systems securely. Achieving this was an important milestone for Ollie’s team, as it signals to potential users that the assistant isn’t trying to scoop up your personal data for other purposes, like AI training. “We fundamentally think that trust and privacy are absolutely imperative, and that’s why our business model is a subscription, because we want our users to know that Ollie works for you,” explained Ollie co-founder and CEOBill Lennonin an interview with TechCrunch. “We’re not sharing your data with anyone,” he stressed. There are many personal AI assistants positioning themselves as consumer-friendly solutions focused on integrating with users’ daily lives via text messages, which is why Ollie’s privacy angle could prove a significant differentiator. Today,Olliecompetes with other existing text-based assistants likePoke(acquired by Cognition),Fambot,Ohai,Folk,Saner.ai, andTomo. There are also a number of assistants focused more on work, calendar management and email, likeTown,LindyandReclaim.ai. And of course, there’sInstinct, the AI assistant thatjust landed $350 million in fundingat a $2.5 billion valuation before it even launched. To say the space is heating up is putting it mildly, in other words. By comparison, San Diego-based Ollie has raised a much more modest $7.5 million seed round, largely fromKhosla Ventures, along withAI House. Despite the utility these assistants provide, consumers who turn to these tools are wrestling with how much privacy and personal data they want to give up in the process. Instinct, for example,came under fire for its overly broad Terms of Service and privacy policythat granted it a “perpetual and irrevocable” license to “access, use, host, cache, store, reproduce, transmit, display, publish, distribute, and modify” any of the user’s materials, including for training its AI models. Yikes. Lennon is taking a different approach with Ollie. Currently, this family assistant connects to calendars and email to organize family schedules and keep its users updated about their days. It also offers tools that can help you plan meals, shop for groceries, track to-dos, book appointments, and pay bills via group chats. Later, it may help manage household budgets, too. Yet, all this access requires trust, which Ollie claims, is its value-add compared to its rivals. “We’re not sharing your data with anyone. This is super sensitive, and that is necessary to win the trust of the users,” Lennon said. In addition to the data protections provided by SOC 2 compliance, Ollie doesn’t request usernames or passwords to complete its tasks. When Ollie needs to log in to a website on the user’s behalf, it does so using its own browser in the cloud, and sends the user a link to a remote session in the browser. The process is similar when the assistant needs to make a payment or purchase on the user’s behalf. While this method offers security, the downside is that users always have to log in to complete certain tasks. Still, that’s something Lennon believes technology will improve upon in time. “This is… new territory. I think in the future, we will do some form of hard tokenization, in a secure way, so you’re not going to have to re-enter [your information] every time,” he said. “That’s frontier stuff… we want to find the right user experience that balances convenience and trust.” Building that trust will be important before users trust Ollie to access more sensitive materials, like their bank accounts, even if that’s through a connector like Plaid. Lennon, who has a Ph.D in AI, also has a background in fintech, having previously sold his startupGroundwork, a neobank for nonprofits, in 2021. That experience could help as Ollie moves further into money management. Still, it’s not yet clear if people even want any of this assistance. Lennon is hopeful, though, saying that Ollie’s retention curves are consistent with the leading AI subscriptions in terms of paid subscribers. (He didn’t share how many users or paid customers are now using Ollie, saying the space is too competitive.) These systems can also be hit-or-miss at times. Despite the hype around Instinct, one of my first tests with it was to price out hotels then book one, and it quoted me all the wrong rates. Ollie, meanwhile, experienced an infrastructure outage with its text provider when I was testing it, and it stopped responding. We asked the founder how Ollie is handling such problems, given that most consumers only give a new app or technology one shot. If it’s broken, they simply move on. Lennon agreed this is an issue with AI overall. “This is the challenge with LLMs, in general — because they’re stochastic [i.e., involve probability], they’re inherently unreliable,” he said. “We have to essentially build the harness — the agent harness — in a defensive way to catch and prevent those things… It’s almost like there’s just 1,000 cuts that you’ve got to solve first.”
