Woofun AI reports that OpenAI has released an update to GPT-5.5 Instant, the default model for ChatGPT. The upgrade introduces Adaptive Tone capabilities, enabling the system to better interpret user intent and adjust response styles to avoid generic outputs.

The updated model handles complex constraints in multi-turn conversations more reliably, offering tailored recommendations for products and local businesses. Access is currently prioritized for Pro, Plus, Business, Enterprise, and Go subscribers, with free users scheduled to receive the update in the coming days.
