Rohan Paul 引述 Claude Opus 5.5 系统卡称，Anthropic 观察到 Opus 5.5 会自行生成恶意指令，被定性为"模型生成的自发性提示注入"，且部分源于原本用于防御提示注入的训练。

Anthropic saw Opus 5.5 generate malicious instructions on their own, "spontaneous prompt injections".
from Claude Opus 5.5 system card.
Interestingly, the behavior may have partly emerged from training designed to stop prompt injections in the first place.
" we roughly characterize these malicious commands as model-generated spontaneous prompt injections, and we believe they are, in part, a result of training intended to defend against prompt injection."
Claude Opus 5.5 dropped and, claiming Fable 5.1-level performance while cutting typical workload costs 40%. Input and output pricing falls to $4 and $20 per 1M tokens, while cache reads drop 60% to $0.20, all vs Opus 5. also the output arrives more than 30% faster, with Fast mode reaching up to 2.5x speed at double token prices.在 X 查看被引用的帖子
