OpenAI's GPT-5.5 is now the default model for all OpenAI actions in Tines. GPT-5.5 is OpenAI's most capable model yet – it handles multi-step reasoning more reliably, produces more accurate outputs, and navigates ambiguity without getting stuck.

For your stories, this means AI actions powered by OpenAI will deliver better results out of the box, whether you're classifying alerts, summarizing data, extracting key fields, or generating human-readable messages. No changes needed – existing stories using the default model will automatically use GPT-5.5.
