Claude is Anthropic’s AI, like ChatGPT but more capable. I was a casual user until the 23 October release (informally “Claude 3.6”), when it crossed a quality threshold I didn’t even know was there. It is really, really good. I have been using it a lot more since, and I got curious as to how much more.

Principles for coding securely with LLMs
Writing code with LLMs is fundamentally different from other ways of programming. LLMs are often non-deterministic and always unpredictable. They have a capability that no other technology can match: the ability to interface with natural language. What does that mean for security?
