ChatGPT Upgrade Launches GPT-5 with Multi-Mode Options and Model Personalization

According to reports from HashiChain, Sam Altman announced the latest update for ChatGPT, introducing three modes for GPT-5: "Auto", "Fast", and "Thinking". Users can switch between these modes based on their needs. The information limit for GPT-5's "Thinking" mode is 3,000 messages per month; beyond that limit, users can utilize GPT-5 Thinking mini, which has a single context limit of 196,000 tokens. The 4.0 model is back online, and paid users can add more models through settings, while version 4.5 is restricted to Pro users. The official team is developing a more gentle personality for GPT-5 and plans to support user-customized model personalities.
