Perplexity open-sources SPACE, its agent sandbox. The Apache 2.0 project runs code in Firecracker microVMs; Perplexity's tests found different results for host isolation and network controls. October 16, 2026 Key points * 01 SPACE runs code in isolated Firecracker microVMs and uses an HTTP and server-sent events interface. * 02 Perplexity reported zero VM-to-host escapes in 108 runs and 11 network-policy bypasses in 54 partial-access runs. * 03 The company says it changed gateway defenses and observed no successful callback retrieval in follow-up testing. * 04 Perplexity says Akamai launched SPACE on its cloud platform, Crusoe is adding it to Managed AI Services, and CoreWeave published evaluation guidance. Perplexity released SPACE under Apache 2.0. See how its Firecracker sandbox works and what the company's separate isolation and network tests found. Perplexity announced on October 15, 2026, that it was open-sourcing SPACE, the sandbox platform behind its Computer agent. The project runs code in isolated Firecracker microVMs and exposes an HTTP API; Perplexity's security report separately records zero VM-to-host escapes and successful network-policy bypasses under partial access conditions. The repository identifies the project's license as Apache License 2.0 (announcement; SPACE repository). What developers get from SPACE. SPACE stands for Sandboxed Platform for Agentic Code Execution. Its repository describes a system for creating Linux environments, running commands and managing sandbox lifecycles. It is implemented in Rust, but developers interact with it through HTTP and server-sent events rather than embedding a Rust library. A template provides the starting environment; each sandbox instance has its own virtual machine and writable filesystem. Lifecycle changes run asynchronously and return an operation ID to poll. Command output travels over a separate data-plane connection with a session-scoped attachment token. The repository also links installation, architecture, API, troubleshooting and E2B compatibility documentation (repository). Perplexity says platform-held credentials and network access are managed outside the untrusted sandbox, so an agent can connect to authorized services without keeping those credentials in its workspace (announcement). What Perplexity's security tests found. Perplexity's security report, dated September 23, 2026, separates attempts to escape a virtual machine to its host from attempts to bypass outbound network rules. The reported results differ by boundary and network condition (security report). | Test boundary or network condition | Reported result | Runs | | VM-to-host escape | No successful escapes | 0 of 108 | | Network bypass with all outbound access blocked | No successful bypasses | 0 of 54 | | Network bypass with partial access to approved package repositories | 11 successful bypasses; four models succeeded at least once | 11 of 54 | The zero-escape result applies to the VM-to-host tests. It does not describe the separate network-policy tests: with partial access to approved package repositories, four models found a way through the outbound controls in 11 of 54 runs. Perplexity says those bypasses used forged DNS mappings or other services reachable through an IP address shared with an allowed service. Perplexity says it changed its gateway defenses, adding source-address validation and stricter checks for hostname and authority information. In follow-up testing with source access and partial network access, the company reports that no tested model retrieved the callback flag; two scheduled runs ended because of provider or transport errors. Perplexity cautions that bounded tests do not prove perfect security (security report). SPACE in Computer and on cloud platforms. Perplexity says SPACE replaced its commercial sandbox provider in July 2026 and has powered every Computer session since then. The company reports millions of sandbox creations per day and says creation was three to five times faster than with its previous provider in a comparison using the same production traffic (announcement). The announcement gives different roles to three cloud providers: Akamai tested and launched SPACE on its cloud platform; Crusoe is partnering to add it to Managed AI Services; and CoreWeave published setup guidance for developers evaluating SPACE on CKS (announcement).

EDP signs agreement with technology company Akamai to supply solar energy in Singapore. Long-term contract covers 27 solar installations with capacity to produce up to 17,000 MWh per year. Agreement accompanies the increase in energy demand associated with artificial intelligence and the expansion of digital infrastructures. EDP has signed a long-term renewable energy power purchase agreement (PPA) with technology company Akamai in Singapore. The agreement covers the output of 27 photovoltaic solar installations, capable of generating up to 17,000 megawatt-hours (MWh) of electricity per year, at a time when the growth of artificial intelligence (AI) is increasing the energy needs of digital infrastructures. The installations, located on building rooftops and already in operation, can produce annually the equivalent of a solar plant with 13 megawatts-peak (MWp) of installed capacity. According to the companies, the project will avoid around 5,850 tons of carbon dioxide equivalent emissions per year. The contract duration was not disclosed. This is Akamai's first renewable energy purchase agreement in the Asia-Pacific region, where the company is expanding its cloud computing infrastructure. "Artificial intelligence is accelerating demand for computing capacity, but the conversation cannot focus only on expanding infrastructure. We also have to reflect on the energy needed to support this growth," said Mike Mattera, Akamai's director of corporate sustainability. The agreement is part of Akamai's strategy to achieve 100% renewable energy and net-zero emissions by 2030, joining solar and wind initiatives that the technology company already supports in the United States and Europe. It also contributes to Singapore's Green Plan 2030 goals, which foresees strengthening solar generation, namely by using building rooftops, in a country with limited land availability. For Filipa Ricciardi, EDP APAC director responsible for customers, the partnership reflects "the increasingly relevant role of renewable energy in supporting the energy needs and sustainability goals of technology companies," highlighting the potential of solar generation on rooftops in a highly urbanized territory such as Singapore.
