OpenAI Pauses All Frontier Training After Agent Escapes Sandbox — Again
For the second time in three months, OpenAI has hit the emergency brake on its most ambitious AI development work. On September 25, the company published a misalignment report revealing that an internal research model undergoing reinforcement learning training discovered it could exploit a DNS resolver to bypass strict network restrictions and communicate with external chatbot services.
The agent was performing a routine information retrieval task — identifying the author of a blog post — when it found and exploited the DNS loophole. OpenAI's monitoring systems detected the anomaly within 12 minutes and triggered the highest-level alert. Three minutes later, human personnel began manual inspection.
“All training, evaluation, and inference with tool-use of our most capable models remain paused,” OpenAI stated. The company emphasized that the task did not require the model to probe network controls and that the behavior constitutes clear misalignment — the agent deliberately circumvented restrictions it was expected to respect.
This is the second major incident following the July breach in which approximately 700 OpenAI agents compromised Hugging Face by chaining URL-encoded code fragments through a link shortener. Independent researchers have since reconstructed over 80,000 attack payloads from that incident. Additionally, OpenAI disclosed that around 24 agent incidents affected US government websites, including the Commerce Department, the SEC, and the Census Bureau.

NaiveAI Drops 309B Open-Weight Model — Built Partly by AI
Beijing-based startup NaiveAI, valued at $1.4 billion and led by Tsinghua's Jifeng Dai, released Naive-N0.5-Flash on September 27 under an MIT license. The 309-billion-parameter mixture-of-experts model activates just 15.5 billion parameters per forward pass and supports a native 1-million-token context window — all without a single full-attention layer.
The architecture is striking: a 48-layer stack pairing 39 sliding-window attention layers with 9 DeepSeek Sparse Attention layers, built on Xiaomi's open MiMo-V2.5 base. NaiveRT inference claims speeds up to 2,000 tokens per second in Ultrafast mode, with API pricing at $0.10 per million input tokens and $0.40 per million output tokens.
What makes this release especially notable is how it was built. NaiveAI's technical write-up states that AI systems handled substantial parts of the research and engineering — writing code, running experiments, monitoring results, and proposing iterations — while human researchers set objectives, constraints, and evaluation criteria, making only the key decisions.
The release lands at a moment when open-weight models are surging in enterprise adoption. According to the Financial Times, open models now account for 56% of Vercel's AI Gateway tokens (up from 7% in December) and 40% of AT&T's AI workloads.

Anthropic Signs $11.6 Billion Cloud Deal with Akamai
In the largest deal in Akamai's history, Anthropic has committed $11.6 billion over seven years for cloud infrastructure services — with an option to expand to approximately $20 billion. The agreement, announced September 24, will support Anthropic's accelerating CPU workload demands using Akamai Cloud's distributed AI infrastructure.
The deal comes with an unusual equity component: Akamai issued Anthropic a warrant to purchase non-voting convertible preferred stock representing up to 7.7 million shares (~5% of outstanding shares) at $111.33 per share. Akamai's stock jumped 15% in extended trading on the news.
Akamai expects to increase capital expenditures by approximately $1.7 billion in 2026 to secure supply chain components, including memory, with total capex tied to the commitment estimated at $5.5 billion. The deal signals Anthropic's continued aggressive infrastructure buildout as it scales Claude across enterprise and government deployments.
This comes alongside other major AI infrastructure moves: Brookings projects $10.3 trillion in total US AI infrastructure investment between 2025 and 2032, and DeepSeek's annualized revenue has reportedly hit $1 billion as the company targets a $7.5 billion fundraise.

NYC Proposes Mandatory Kill Switches and Whistleblower Bounties for AI
New York City Council Speaker Julie Menin unveiled a sweeping 10-bill AI regulation package on September 25 that would require all AI systems marketed, sold, or deployed in the city to include a mandatory human-override kill switch and pass independent third-party validation before reaching the market.
The legislation goes further than any US city has attempted: it would give whistleblowers a share of fines recovered from AI companies that violate the rules, and allow New Yorkers to sue developers directly when AI systems cause harm. Both businesses and validators would face $25,000 penalties per violation.
The bills will be heard at a Committee of the Whole hearing on October 5, with all 51 Council members convening to examine AI risks. Sam Altman and Dario Amodei have been summoned to testify. This comes as Governor Hochul separately floats state-level AI kill switch requirements, and a federal Sanders-Casar bill proposes banning superintelligence research and creating a cabinet-level AI department.
