• In this post, we break down the current situation, discuss the role of openness, and situate the future of cybersecurity within the larger AI ecosystem.
• Mythos is a “frontier AI model” , a large language model (LLM) that can be used to process software code (among many other things).
• This follows a general trend in LLM development, where LLM performance on code-related tasks has recently skyrocketed.
• What’s particularly significant about Mythos is the system it’s embedded within: It's the system, not the model alone, that has enabled Mythos to rapidly find and patch software vulnerabilities.
• Understanding this distinction is key to understanding the current landscape of AI cybersecurity.
