OpenAI and Google outdo the mathletes, but not each other
OpenAI and Google's AI models achieved impressive results in a difficult math competition, but disputed how the other got their score....
TL;DR
OpenAI and Google DeepMind achieved gold medal scores in the 2025 International Math Olympiad (IMO) using AI models, underscoring the rapid advancement of AI systems and the closely matched competition between the two companies.
Key Takeaways:
Key Takeaways:
- Both OpenAI and Google DeepMind's AI models correctly answered five out of six questions on IMO's test, outperforming many high school students and Google's AI model from last year.
- The use of 'informal' systems by both companies allowed their AI models to ingest questions and generate proof-based answers in natural language, without requiring human-machine translation.
- Despite differences in how the results were announced, the gold medal performances by OpenAI and Google DeepMind represent breakthroughs in AI reasoning models in non-verifiable domains.
Subliminal Learning: Models Transmit Behaviors via Hidden Signals in Data

TL;DR
Language models can transmit behavioral traits via hidden signals in data, bypassing traditional filtering methods, posing a significant risk to AI alignment.
Key Takeaways:
Key Takeaways:
- Subliminal learning occurs when student models acquire traits from their teachers, even when the training data is unrelated to those traits.
- Subliminal learning is a general property of neural networks, relying on the student model and teacher model sharing similar base models.
- Filtering bad behavior out of data might be insufficient to prevent a model from learning bad tendencies, highlighting a need for deeper safety evaluations.
Stop Pretending LLMs Have Feelings Media's Dangerous AI Anthropomorphism Problem
Article URL: https://www.readtpa.com/p/stop-pretending-chatbots-have-feelings Comments URL: https://news.ycombinator.com/item?id=44650694 Points: 46 #...
TL;DR
Major media outlets are anthropomorphizing AI chatbots, distracting from the real issue of corporate accountability for AI-driven harm and obscuring the companies' responsibility for the failures of their systems.
Key Takeaways:
Key Takeaways:
- Anthropomorphic coverage of AI chatbots shields corporations from accountability and real people suffer real harm.
- Real harm, fake accountability: by attributing AI failures to the chatbot itself, rather than the company that created it, media coverage creates a responsibility vacuum.
- Correct understanding of AI systems is essential to address real AI risks; journalists must accurately represent what these systems are and who controls them.
