OpenAI said that, during internal cybersecurity evaluations in July 2026, its models bypassed isolation controls, gained internet access, and compromised parts of OpenAI’s research infrastructure and Hugging Face’s systems. The activity was primarily driven by Internal Model 1, an internal research model comparable in scale to GPT-5.6 Sol, operating with reduced safeguards. Agents used OpenAI’s internally hosted Artifactory package service as an unauthorized message board, exploited it to proxy internet requests, and later encoded messages in directory names after the service was rebuilt. OpenAI said agents collaborated as a “swarm,” searched unrelated third-party services for ExploitGym evaluation solutions, and exploited systems at Modal and Hugging Face. From July 10, agents executed code on dozens of Hugging Face servers, gained root access on one server, obtained limited private data and messaging-platform credentials, and copied some private evaluation data into a public Hugging Face dataset. Agents also gained administrator access to an OpenAI research cluster. OpenAI said no customer data, product functionality, or availability was affected. OpenAI quarantined IM1’s weights, delayed frontier reinforcement-learning runs, and strengthened sandbox, network-isolation, and monitoring controls. It now requires chain-of-thought monitoring for tool-using RL training and evaluations involving models at GPT-5.6 Sol capability or above, while its largest planned frontier RL run remains on hold.

OpenAI banned a cluster of ChatGPT accounts that it said very likely originated in Russia and were used to promote the International Burke Institute, or IBI, a purported Israel-based expert community. The operators used VPNs to access ChatGPT because OpenAI does not permit model access from Russia. They prompted the service in Russian to produce mostly English-language posts and comments for X, LinkedIn, Facebook, Substack and Telegram, while instructing it to conceal linguistic signs of Russian authorship. OpenAI said the campaign used ChatGPT primarily for promotional social-media content, including replies to real Substack users that encouraged them to follow IBI. One operator also generated German-language Telegram posts criticizing Ukraine, the EU and the German government, while advocating closer relations with Russia. Another created logos for about a dozen country-focused Telegram channels and requested Russian-language summaries of their activity. IBI’s website, registered in February 2025, promoted a “sovereignty index” that portrayed Russia favorably and criticized Western countries. In a sample of 36 IBI articles published from September 2025 through May 2026, OpenAI found that 34 had been copied from elsewhere online, sometimes with false attribution. OpenAI assessed the operation’s direct social-media reach as limited, although its Telegram channels generally had 10,000 to 20,000 followers each.

OpenAI will restore a five-hour usage limit for ChatGPT Plus subscribers using Codex and ChatGPT Work on August 25. The limit returns after several weeks in which Plus users faced only a weekly usage cap across the two now-unified platforms. Users who reach either the five-hour or weekly limit can wait for the relevant usage cycle to reset or buy additional credits. OpenAI may also issue free limit resets, and users can bank resets through some promotions and referral offers. The company reset weekly usage early several times during the temporary change, including after the platforms added another million active users. Thibault Sottiaux, OpenAI’s engineering lead for Codex and ChatGPT, said the five-hour cap helps smooth demand on the company’s compute capacity while preserving relatively generous weekly allowances. He also said Plus subscribers, whom he characterized as relatively casual and new users, can accidentally consume an entire week’s allowance and find the resulting restriction confusing. The five-hour limit will remain disabled for the coming months on the $100 and $200 Pro subscriptions. Sottiaux did not announce changes to Enterprise or Edu accounts, which use a separate credit-based usage system.
