DeepSeek is the only one that I can directly ask about vulnerabilities and it will give me a PoC. Although not as good as others, it has helped me with security research.

they [anthro] took the risk of looking like a toy, rather than possibly assist an exploit.

Deepseek training is not finished yet, it's a preview.

And yes, it's an excellent model.
