Tech community debates are questioning the validity of Anthropic's claims regarding its closed Mythos model and its advanced cybersecurity capabilities compared to open-source alternatives. Skeptics argue that without transparent testing setups, these assertions serve as marketing rather than proof, raising concerns about whether artificial intelligence genuinely discovers complex vulnerabilities or merely games benchmarks. The discussion also highlights broader disagreements over whether strong coding proficiency naturally translates to identifying arbitrary security flaws, emphasizing the need for practical and reproducible verification.

A new technique leverages a modified LLVM fork to retrofit JIT compilation directly into C-based interpreters by optimizing the interpreter's underlying execution loop. By manually annotating the interpreter's C code, developers can significantly boost performance, such as doubling execution speed for Lua, without altering the actual programs being interpreted. While the approach currently requires specialized knowledge and manual modifications, it offers a promising method for accelerating language interpreters that could potentially be automated in the future.

YC W26 startup Kampala allows developers to reverse-engineer private applications into usable APIs by analyzing network traffic and HAR files.
