Maintaining state and context of conversations between a user and digital assistant using threads

A computer-implemented method comprising:

• receiving, at a digital assistant, a natural language utterance from a user during a session between the user and the digital assistant;
• obtaining a topic context instance for the natural language utterance;
• generating, by a generative artificial intelligence (GenAI) model, a list comprising an executable action based on one or more candidate actions associated with the topic context instance;
• executing the executable action to produce an output, wherein the executing comprises:
• determining there is no thread running within the session that is associated with the topic context instance, the executable action, or both,
• responsive to determining there is no thread running, creating a thread associated with the topic context instance, the executable action, or both, wherein the thread maintains the topic context instance, the executable action, or both as a separate context from that of context associated with any other conversations for a distinct conversation comprising the natural language utterance between the user and the digital assistant, and
• executing, using the thread, the executable action to obtain the output;
• and
• sending the output or a communication derived from the output to the user.

A system comprising:

• one or more processors;
• and
• one or more computer-readable media storing instructions which, when executed by the one or more processors, cause the system to perform operations comprising:
• receiving, at a digital assistant, a natural language utterance from a user during a session between the user and the digital assistant;
• obtaining a topic context instance for the natural language utterance;
• generating, by a generative artificial intelligence (GenAI) model, a list comprising an executable action based on one or more candidate actions associated with the topic context instance;
• executing the executable action to produce an output, wherein the executing comprises:
• determining there is no thread running within the session that is associated with the topic context instance, the executable action, or both,
• responsive to determining there is no thread running, creating a thread associated with the topic context instance, the executable action, or both, wherein the thread maintains the topic context instance, the executable action, or both as a separate context from that of context associated with any other conversations for a distinct conversation comprising the natural language utterance between the user and the digital assistant, and
• executing, using the thread, the executable action to obtain the output;
• and
• sending the output or a communication derived from the output to the user.

One or more non-transitory computer-readable media storing instructions which, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, at a digital assistant, a natural language utterance from a user during a session between the user and the digital assistant;
• obtaining a topic context instance for the natural language utterance;
• generating, by a generative artificial intelligence (GenAI) model, a list comprising an executable action based on one or more candidate actions associated with the topic context instance;
• executing the executable action to produce an output, wherein the executing comprises:
• determining there is no thread running within the session that is associated with the topic context instance, the executable action, or both,
• responsive to determining there is no thread running, creating a thread associated with the topic context instance, the executable action, or both, wherein the thread maintains the topic context instance, the executable action, or both as a separate context from that of context associated with any other conversations for a distinct conversation comprising the natural language utterance between the user and the digital assistant, and
• executing, using the thread, the executable action to obtain the output;
• and
• sending the output or a communication derived from the output to the user.
