Perplexity publishes red-team research on its SPACE sandbox for Computer agents
@perplexity_ai on X published this on Nov 11, 2026 (source: x.com).
Perplexity's official account said on 11 November 2026 at 18:21 UTC that it is publishing new research from red-teaming SPACE, its VM sandbox for Computer agents. The post says 12 models were given two tasks: escape the VM to take a credential from the host, and bypass SPACE's network policy to reach a blocked URL. Perplexity says the standard Capture the Flag setup used in red-teaming can steer agents away from the security boundary being tested, and that security-specialized models do not guarantee better results.

Perplexity introduces JOLT, a post-training method that matched GRPO on MATH with 6.5x fewer training tokens
@perplexity_ai on X published this on Oct 21, 2026 (source: x.com).
Perplexity says JOLT trains one model as both teacher and student, with the teacher learning to give feedback the student can use. On MATH it matched GRPO accuracy using 6.5 times fewer training tokens.

Perplexity Agent API adds GPT-6 Astra and DeepSeek V4 Pro, and older Claude, Gemini and Grok models are no longer listed
Perplexity Agent API models published this on Oct 17, 2026 (source: docs.perplexity.ai).
Perplexity's Agent API models page now lists openai/gpt-6-astra at $10 per million input tokens and $50 per million output tokens for inputs up to 272k tokens, with flex and priority service tiers, and perplexity/deepseek-v4-pro-0813 at $1.32 per million input tokens, $3.96 output and $0.044 for cached reads. Older models including Claude Opus 4.8 and Grok 4.3 no longer appear in the model list.

Perplexity open-sources SPACE, the Firecracker microVM sandbox that runs every Perplexity Computer task
Perplexity published this on Oct 16, 2026 (source: github.com).
Perplexity has released SPACE (Sandboxed Platform for Agentic Code Execution) on GitHub under the Apache 2.0 license. Written in Rust, it gives each agent task its own Firecracker microVM, keeps credentials out of the guest by injecting them at the network layer, and enforces egress policy through a per-sandbox gateway; it needs a Linux x86_64 host with KVM. Perplexity says median sandbox creation fell from 185 ms to 60 ms versus its previous provider. In its own red-team study, none of 108 runs across 9 models escaped to the host, while 11 of 54 partial-network runs bypassed the egress policy before fixes and none after.

Perplexity details how its SPACE sandbox uses cryptographic identity to route requests across millions of daily executions
Perplexity published this on Oct 14, 2026 (source: perplexity.ai).
Perplexity says SPACE, its sandbox for running code, handles millions of executions a day with an error rate below 0.0002%. A new engineering post explains how it uses cryptographic identity to keep each request tied to the right execution as sandboxes pause, resume and move.

Perplexity explains the Git-forge filesystem behind Perplexity Projects for agents
@perplexity_ai on X published this on Oct 12, 2026 (source: x.com).
Perplexity published a post on how it built the filesystem behind Perplexity Projects as a Git forge for agents. Each agent works in its own sandbox and commits to a shared repository, so people and other agents can build on its work across sessions.
