    Mythos finds a curl vulnerability

    Anthropic's AI model, Mythos, was touted for its advanced security flaw detection capabilities, but its real-world impact has been met with skepticism. While Anthropic claimed Mythos was exceptionally good at finding vulnerabilities, the curl project maintainer reported that the AI only identified a single low-severity flaw after extensive analysis. This has led to criticism that the hype surrounding Mythos was largely a marketing stunt, especially given the project's existing robust security scanning practices which have already uncovered hundreds of bugs.

    IMPACT Questions the effectiveness of AI in identifying critical security vulnerabilities, suggesting current hype may outpace actual capabilities.

    Open weights are quietly closing up - and that's a problem

    Researchers are exploring new methods to enhance AI safety and efficiency. One paper proposes a language-agnostic approach to detect malicious prompts by comparing query embeddings against a fixed English codebook of jailbreak prompts, showing promise but also limitations under distribution shifts. Another study investigates how the wording of schema keys in structured generation tasks can implicitly guide large language models, revealing that different models like Qwen and Llama respond differently to prompt-level versus schema-level instructions. Separately, a discussion highlights the increasing importance and evolving landscape of open-weights models, noting that while they offer cost and privacy advantages, their availability and licensing are becoming more restrictive.
