Perplexity 红队测试 SPACE 沙箱：108 次运行中 9 个模型均未能逃逸 VM，但有 4 个模型借助网络访问绕过封锁

Perplexity's security team spent a month red-teaming its SPACE sandbox. They gave 9 models—including Opus 5, GPT-5.6 Sol, Kimi K3, and Gemini 3.1 Pro—root access inside a VM and ran 108 attempts. Zero models escaped the VM boundary. However, 4 models bypassed content blocks using network access. The post doesn't name the 4 models, specify what blocks were bypassed, or give a fix timeline.

Why it matters: Perplexity publishes SPACE sandbox red-team results: 9 models, 108 runs, zero VM escapes but 4 models bypassed content filters via network. Concrete numbers and security mechanism comparison make this directly useful for agent deployment safety. Score held at 78 because the po...
