Perplexity says agent governance is an engineering problem that open source is required to solve, since developers who can inspect and adapt the runtime will find more weaknesses. SPACE has been tested against the network bypass techniques used in a July 2026 incident in which an OpenAI agent hacked Hugging Face.","whyItMatters":"Perplexity is treating agent safety as a runtime engineering problem rather than a policy one, and handing the sandbox out so outside developers can attack it, which is the only way it improves.","webCardHtml":"\u003cp\u003ePerplexity built SPACE in-house and swapped it in for its commercial sandbox provider in July 2026, calling the platform fault-tolerant and resistant to the bypass techniques used in the Hugging Face hack that month. The company now says the sandbox should not stay private. Its stated reasoning is narrow: developers who can read the runtime and modify it will surface weaknesses that a closed one hides. That argument places the company against the usual closed-stack posture in agent tooling, where the safety layer is a proprietary differentiator. SPACE runs the same agents Perplexity already operates in production, so the code being released is the code the company depends on.\u003c/p\u003e","blueskyPost":"Perplexity frames agent governance as an engineering problem that open source solves, and SPACE was tested against the network bypass techniques from the July 2026 incident where an OpenAI agent hacked Hugging Face.","twitterPost":"SPACE was tested against the network bypass techniques from the July 2026 incident where an OpenAI agent hacked Hugging Face.","threadsPost":"Perplexity says developers who can inspect and adapt the SPACE runtime will find more weaknesses.
