RESEARCHERS ARE TRAINING AI TO INTERPRET ANIMAL EMOTIONS

Several teams around the world are working on AI systems to help humans understand animals. A group at the University of the West of England Bristol and Scotland's Rural College have developed a system called Intellipig that examines photos of pigs' faces and notifies farmers if there are signs of pain, sickness, or emotional distress, and a team at the University of Haifa is training AI to identify signs of discomfort in dogs' faces. These systems still rely on humans to do the initial work of identifying the meanings of different behaviors.

I WAS GIVEN EARLY ACCESS TO GROK 3 EARLIER TODAY, MAKING ME I THINK ONE OF THE FIRST FEW WHO COULD RUN A QUICK VIBE CHECK

Grok 3 has an around state-of-the-art thinking model that is able to solve some advanced questions. It is likely somewhere around o1-pro in terms of capability and ahead of DeepSeek-R1. DeepSearch can produce high quality responses to various research- or lookup-type questions, but it can still hallucinate information - even URLs. Overall, Grok 3 + Thinking feels somewhere around the state-of-the-art territory of OpenAI's strongest models, and slightly better than DeepSeek-R1 and Gemini 2.0 Flash Thinking.
