There's a rate limit of 3,000 messages per week with GPT-5 Thinking, and additional messages can be sent using GPT-5 Thinking mini beyond this limit. The context limit for GPT-5 Thinking is 196k tokens.
Rate limits may be adjusted based on demand.
Model 4o is available again for all paid users by default. Any potential deprecation will be announced well in advance.
Paid users can also toggle on "Show additional models" in ChatGPT web settings to access models like o3, 4.1, and GPT-5 Thinking mini. Model 4.5 is exclusive to Pro users due to its high GPU cost.
An update is in progress for GPT-5’s personality, aiming for a warmer tone without being as off-putting to some users as GPT-4o. There is a focus on providing more customization options for model personality per user.
