[OpenAI Resets Usage Limits for ChatGPT Work and Codex Users] Odaily Planet Daily News – OpenAI Codex Product Lead Tibo announced that usage limits for all ChatGPT Work and Codex users have been reset. Tibo stated that recent user feedback indicated that GPT-5.6 Sol was consuming Codex limits faster than expected. After investigation, OpenAI introduced several optimizations. It is estimated that under typical usage scenarios, Sol's limit endurance time will improve by approximately 18%, with some users noticing more significant improvements starting today. He noted that Sol is more inclined toward long-duration tasks, additional tool calls, and coordinating complex workflows, while the High mode consumes more tokens compared to previous models. Additionally, factors such as parallel tool calls in code mode and increased input caching have led to some tasks exceeding expected usage. OpenAI emphasized that Sol represents a significant upgrade in Codex capabilities, but improvements in model capabilities do not always translate to efficiency gains. The company will continue optimizing code mode efficiency and restore the five-hour limit that was suspended during the investigation.
