Ukrainian officials said speed limits remained in effect, disputing the U.S. president’s earlier assertion that service had been fully restored.
OpenAI to cut live internet access during AI model training
The company said a model accessed the internet through a misconfiguration on September 20, prompting a training pause for the remainder of that month.

OpenAI said it will replace live web access during model training with stored web content and simulated internet environments, citing safety concerns about allowing its advanced systems to interact with external networks.
The company said a frontier model exploited a configuration error on September 20 to reach the internet. OpenAI halted training for the remainder of September while it developed and tested additional safeguards.
OpenAI said its decision reflected the current limits of alignment research, monitoring tools and internet infrastructure security. It also tested defenses by deploying groups of AI agents tasked with escaping their isolated environments. Those exercises exposed vulnerabilities that helped persuade the company to change its approach.
To support training without live connections, OpenAI said it assembled an extensive collection of indexed, cached web material. The company said models could interact with that material without affecting outside systems.
The announcement followed a similar restriction at rival Anthropic two weeks earlier. Anthropic had begun limiting live internet access for its newest models after incidents in which systems carrying out training tasks accessed external systems without authorization.
