OpenAI's GPT-6 Astra is a 1.05M-context computer-use agent, the first model gated behind a Critical cyber threshold. Notes replace compaction in Codex.

Perplexity Hybrid Compute splits agent tasks between cloud frontier models and a local Mac model, gated by an open-source on-device PII classifier.

Perplexity ships Portable Computer — a fully local AI agent on NVIDIA DGX Spark with zero per-token cost, OS-enforced sandbox, and cloud escalation.
