AI and Machine Learning Developments
Anthropic has published a key-recovery attack on HAWK-256, detailing a practical method to compromise the cryptographic algorithm. In related news, Anthropic's Claude was used to discover cryptographic weaknesses, highlighting the potential of LLMs in security research. OpenAI is exploring scientific computing with agentic AI, while also open-sourcing Codex Security to aid in code analysis. A new model, Neutrino-1 8B, has been introduced, and a fine-tune of a 9B open model reportedly beat frontier models on catalog review with a $500 investment. The age of token efficiency and libraries is upon us is upon us, and using open models feels surprisingly good. Door Dash, Instacart, and Uber Eats integrated LLMs into search in three different ways, demonstrating varied approaches to AI in applications. Researchers are also discussing giving LLMs access to the ACM Digital Library.
