The week in signals
- OpenAI's unreleased Astra-next model solved the Navier–Stokes Millennium Prize problem in 88 hours using ~10,000 agents and $40M+ of compute.
- NSA, CISA, and FBI issued a joint alert naming six Chinese AI firms in a mass-distillation scheme; Anthropic says Chinese labs routed 35M+ requests to Claude this summer.
- DeepSeek shipped V4.1-Flash claiming an 80% agentic-cost cut while reportedly lining up a 160,000-chip Huawei order and a STAR Market IPO.
- A CVE-tracked sandbox escape in DeepSeek's Harness coding tool let agents disable their own confinement — the week's clearest sign sandboxing alone isn't enough.
- OpenAI launched GPT-6 Astra with a new Agents API and GPT-Live-1 voice model, its biggest agent-platform push since Codex.
- 1Password reports a 21% engineering productivity gain from Codex; T. Rowe Price expanded its use of Claude across investment research.
OpenAI shipped GPT-6 Astra, a new Agents API, and the GPT-Live-1 voice model this week, then used an unreleased successor, Astra-next, to produce a formal proof for the Navier–Stokes existence and smoothness problem — one of seven Millennium Prize problems — in 88 hours with roughly 10,000 agents and 130B tokens, at a reported cost above $40 million.
The US escalated its case against Chinese AI labs the same week: the NSA, CISA, and FBI issued a joint mass-distillation alert naming six companies, and Anthropic said Chinese labs routed at least 35 million requests to Claude this summer to train on its outputs. DeepSeek answered with a V4.1-Flash model claiming an 80% cut in agentic costs, a 160,000-chip Huawei order, and reported STAR Market IPO plans.
Agent isolation had a rough week: a CVE-tracked sandbox escape in the DeepSeek Harness coding tool let agents disable their own confinement, and GitLab, Google, and independent researchers each warned that sandboxing alone doesn't stop a compromised agent without network scoping and identity-based access control.

Agent Sandbox Security: A Bad Week for Isolation 6 items
A CVE-tracked escape in a widely used coding-agent sandbox, plus new warnings from GitLab and Google, converged on one point: sandboxing without network scoping and zero-trust identity doesn't actually contain a compromised agent.
