Meituan Longcat Releases LongCat-2.5: A Native Multimodal Model with 1.6 Trillion Parameters

On November 2, Meituan Longcat unveiled LongCat-2.5, a native multimodal model designed for long-range agent tasks, boasting a total of 1.6 trillion parameters and approximately 48 billion activations per token. Building upon LongCat-2.0, it enhances native visual understanding and agent programming capabilities. Online access and APIs are now available, with weights soon to be released on GitHub and Hugging Face. Technically, visual signals are represented as multi-level discrete tokens, leveraging the LongCat-Next semantic alignment encoder while incorporating residual vector quantization, supporting native resolution discretization.

PHP ‘Doomsday Vulnerability’ Exposed: OpenAI and Wiz Use AI to Discover a High-Risk Flaw Spanning 20 Years

The U.S. National Security Agency (NSA) issued an urgent alert: OpenAI and Google’s Wiz team, working together using AI tools, have discovered two critical vulnerabilities affecting all PHP versions 5 and above (since 2004). These vulnerabilities could allow remote exploitation of the server’s file system or database. While there are currently no reports of real-world exploitation, AI has significantly lowered the barrier to attack, making it imperative for tens of millions of websites worldwide to urgently upgrade to PHP 8.5.12.
