OpenAI upgrades operator agent
OpenAI is rolling out an upgrade to Operator, its AI agent capable of browsing the web and using software in a cloud-hosted virtual machine. The update replaces the previous GPT-4o-based model with one built on o3, a newer model from OpenAI’s "reasoning" series. According to OpenAI, o3 offers superior performance in math, logic, and decision-making tasks. The upgraded o3 Operator has been fine-tuned with additional safety data to improve boundaries around confirmations, refusals, and security, making it more resistant to prompt injection and misuse than its predecessor. While the API version of Operator will continue using GPT-4o, the new o3 model does not include native terminal or coding access, despite inheriting strong coding capabilities.

Microsoft's model Aurora can forecast the weather
Microsoft Research has introduced Aurora, a foundation AI model designed to forecast a wide range of environmental events beyond traditional weather, including air quality, ocean waves, and tropical cyclones. Detailed in Nature, Aurora outperforms existing systems in both speed and accuracy across 91% of forecasting benchmarks when fine-tuned. Trained on over one million hours of atmospheric data from diverse sources, Aurora uses a flexible architecture to produce forecasts in seconds, about 5,000 times faster than traditional models, at a fraction of the cost. It correctly predicted Typhoon Doksuri’s landfall four days in advance and exceeded industry standards in wave forecasting and air quality prediction despite limited training data. Unlike conventional models, Aurora can be quickly adapted for new forecasting tasks with modest fine-tuning. Microsoft has open-sourced the model and its weights to encourage further research and development. Aurora is now integrated into MSN Weather and available through Azure AI Foundry Labs.
