Leveraging inferred context to improve suggested messages

A computer-implemented method for generating a suggested reply message using a generative artificial intelligence (AI) model, the method comprising:

• receiving a selection of a message in a message thread, the message comprising a header and a body;
• determining, from the header, a sender of the message;
• extracting one or more previously sent messages, outside of the message thread, that were sent from a recipient of the message to the sender of the message;
• querying at least one data source for additional data relating to at least one of the recipient or the sender of the message;
• generating a prompt including at least a portion of the body of the selected message, the additional data, at least a portion of the previously sent messages, and a request phrase requesting a draft reply to the selected message;
• providing, as input to a generative AI model, the generated prompt;
• receiving, from the generative AI model, an output including the draft reply;
• and
• surfacing the draft reply in a user interface.

A system for generating a suggested reply message using a generative artificial intelligence (AI) model, the system comprising:

• at least one processor;
• and
• memory storing instructions that, when executed by the at least one processor, cause the system to:
• cause a display of a user interface of an email application;
• receive a selection of an email from within the user interface;
• query a data source for additional data relating to at least one of a recipient or a sender of the email;
• based on the sender of the email, extract one or more previously sent emails that were sent from the recipient to the sender;
• combine the at least a portion of the selected email, the additional data, at least a portion of the previously sent emails, and a request phrase to form a prompt, the request phrase requesting a draft reply to the selected email;
• provide the prompt to a generative AI model;
• receive, in response to the prompt, an output from the generative AI model including the draft reply;
• and
• cause a display of the draft reply in the user interface.
