Google DeepMind released Natural Forests of the World 2020, an AI-generated map that distinguishes natural forests from plantations and other tree cover using satellite imagery. The model achieved 92.2% accuracy at 10-meter resolution across all land on Earth, trained on over 1.2 million patch locations and validated against an independent global dataset. The map provides a baseline for compliance with deforestation regulations like the EU's EUDR and supports corporate supply chain monitoring, government oversight, and conservation efforts.
Google DeepMind released SIMA 2, an AI agent that can play video games, reason about objectives, and improve itself through self-directed play by integrating Gemini's reasoning capabilities. The agent was trained across commercial video games and demonstrated performance approaching human-level play on tasks it had never encountered before, including untrained games like Minecraft and ASKA. SIMA 2 can now explain its reasoning to users, understand complex instructions in multiple languages, and learn new skills independently without human-generated training data in subsequent iterations.
OpenAI is developing sparse model techniques to understand how neural networks process information and make decisions. Researchers are using mechanistic interpretability methods to identify which parts of networks are responsible for specific behaviors. This work aims to make AI systems more transparent and predictable, potentially supporting safer deployment of these systems.
OpenAI added group chat functionality to ChatGPT, allowing multiple users to collaborate in a single conversation thread. Users can invite others to join existing chats and work together with ChatGPT in real time. This enables shared brainstorming, document editing, and collaborative problem-solving without needing separate individual conversations.
Philips is training 70,000 employees to use AI responsibly as part of an effort to increase AI literacy across the company. The training uses ChatGPT Enterprise and covers application of AI tools in healthcare settings. The program aims to enable workers to incorporate AI into their roles while maintaining responsible practices.
OpenAI released GPT-5.1 through its API with faster adaptive reasoning capabilities and extended prompt caching. The model includes new apply_patch and shell tools alongside improvements to coding performance. Developers can now use these enhanced features for faster inference and reduced token usage through expanded caching options.
