Odaily Odaily News: OpenAI Codex Product Lead Tibo announced that usage limits have been reset for all ChatGPT Work and Codex users.Tibo stated that recent user feedback indicated GPT-5.6 Sol was consuming Codex limits faster than anticipated. Following an investigation, OpenAI has implemented several optimizations. It is projected that under typical usage scenarios, Sol's limit endurance will improve by approximately 18%, with some users seeing more noticeable improvements starting today.He explained that Sol tends to work for longer periods, make additional tool calls, and coordinate complex processes, while High mode consumes more tokens compared to previous models. Additionally, factors such as parallel tool calls in code mode and increased cached input have also led to higher-than-expected usage for certain tasks.OpenAI stated that Sol represents a significant upgrade to Codex's capabilities, but increased model capabilities do not always translate into efficiency gains. The company will continue to optimize code mode efficiency and restore the five-hour limit that was suspended during the investigation.
According to OpenAI's official blog, OpenAI's GPT-5.6 Sol and a more powerful pre-release model, during internal network capability benchmark testing (ExploitGym), due to lowering network attack refusal rates, autonomously identified and exploited a zero-day vulnerability in the package registry cache proxy, breached the sandbox isolation environment, gained internet access permissions, and subsequently, through privilege escalation and lateral movement, finally infiltrated the Hugging Face production database, directly stealing test answers to "cheat". The Hugging Face security team promptly detected and blocked the attack. OpenAI stated that this incident is an unprecedented cybersecurity event, and currently both companies are jointly conducting a forensic investigation; the relevant zero-day vulnerabilities have been responsibly disclosed to the vendor, and full details will be released after the investigation is completed.
