OpenAI's ChatGPT, xAI's Grok, and Anthropic's Claude are all experiencing issues. At around 11AM ET, ChatGPT started returning error messages for users trying to use the chatbot, with its status page saying there are currently "elevated errors across ChatGPT and Codex." In addition to preventing users from having conversations with ChatGPT, the outage is also affecting logins, file uploads, voice mode, search, deep research, image generation, and more. OpenAI says it has "applied a mitigation" and is "monitoring recovery," though its AI tools are still experiencing "degraded performance." The...

Google DeepMind releases WeatherNext 3, an updated weather forecasting AI model with improved accuracy.

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 […]

Google is rolling out an updated AI weather model that's supposed to be more accurate, especially when it comes to predicting rain and snowfall. In the announcement today, the company says it's now able to make forecasts with "unprecedented resolution" using its new WeatherNext 3 AI model. It can produce a global picture that's five times sharper than Google's previous model by learning from real-time weather observations, according to the company. "One of the main developments is for [WeatherNext 3] to go beyond what data most global AI models train on," says Samier Merchant, a research engi...

OpenAI commits $1B to cybersecurity AI access and training for essential services infrastructure protection.

Nvidia has agreed to buy Hugging Face for $12.93 billion, bringing one of the most popular hosting platforms for open-source AI models, datasets, and tools under the ownership of the world's biggest AI chipmaker. Hugging Face is an online platform founded in 2016 that gives AI developers a space to share their projects and data with other users and the general public. It's often described as the "GitHub" for AI due to its browsable library of open-source machine learning models and emphasis on community collaboration features. "Together, we will scale Hugging Face's platform, strengthen its i...

llm-openrouter 0.7.1 ships performance fix for loading OpenRouter models.

OpenAI’s new Astra model will use “recurrent depth,” a technique that allows the model to operate outside of the sequential thinking that characterizes most reasoning models.

Google launched Gemini 3.8 Flash, arriving just a few weeks after its predecessor. The company claims the new model "works harder" than Gemini 3.7 Flash by performing more reasoning steps on complex tasks and "calling tools iteratively." It has the same introductory pricing as 3.7 Flash, $0.75 per million input tokens and $3.75 per million output tokens, but could still end up costing users more. Google warns that "the model might use more tokens to maximize performance, especially at higher effort levels." Developers can keep using Gemini 3.7 Flash if they want to minimize token usage.
