OpenAI Codex & GPT-5.6 Sol: Limits Lifted, More Efficient

OpenAI has temporarily removed the five-hour usage limit for its Codex and ChatGPT Work plans. This change applies to Plus, Business, and Pro subscribers. OpenAI also reset everyone's usage and made their GPT-5.6 Sol model more efficient. These updates were announced by Thomas "Tibo" Sottiaux, who leads the effort at OpenAI. He described the last 48 hours as "intense" due to a surge in demand after the recent GPT-5.6 Sol launch. The efficiency improvements mean GPT-5.6 Sol now consumes less per query. Users report that Sol "feels unlimited." These are temporary measures, and no end date has been given. This means users have more room to build with these tools right now.
