UPDATES TO CHATGPT

Summary from the TLDR AI newsletter

Users can now choose between Auto, Fast, and Thinking modes for GPT-5, rate limits are now 3,000 messages per week with GPT-5 Thinking, 4o is back in the model picker for all paid users by default, and OpenAI is working on an update to GPT-5's personality to make it feel warmer than the current personality but not as annoying as GPT-4o.
