IMO 2025 Competition Results Announced, AI Models Underperform: At the International Mathematical Olympiad (IMO) 2025 held in Australia, several AI models participated, but their performance was not ideal. Claude Sonnet 4, Gemini 2.5 Pro, and ByteDance Seed 1.6 only solved 2/6 problems, with Seed 1.6 and Gemini 2.5 Pro providing complete solutions for one of the problems. Notably, Seed 1.6 employed a relatively older reasoning method. Other models, such as R1 and K2, failed to solve any problems at all. This reflects the current limitations of AI models in tackling complex mathematical problems. (Source: teortaxesTex)
Hugging Face Integrates OpenAI-Compatible API into Transformers: Hugging Face announced that both Vision-Language Models (VLMs) and Large Language Models (LLMs) now have a built-in HTTP server compatible with the OpenAI specification. Users can launch the server using the transformers serve command and connect to their commonly used applications. This means developers can more easily integrate Hugging Face models into their projects and interact using the OpenAI-compatible API, further promoting the popularization and application of open-source AI models.
