Solution Overview

Problem

Existing context management assistants suffer from inaccuracies and inefficiencies in maintaining contextual understanding during multi-turn conversations, particularly due to retokenizing entire conversations at each turn, leading to excessive computational resource consumption.

Innovation Solution

A multi-turn interpreter system that utilizes a context engine and large language model to generate contextual states, pauses execution upon encountering interruption events, and resumes with supplemental data, reducing computational overhead by using context-aware prompts and code instructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the entire conversation is retokenized at each turn to maintain contextual understanding, then contextual accuracy is improved, but computational resource consumption increases

Engineering Contradiction:
Improvecontextual accuracyVSAvoidcomputational resource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent segments the conversation processing into two distinct parts: (1) tokenization of individual turns which is computationally efficient, and (2) maintenance of a separate conversation state object that stores contextual information. This segmentation allows the system to avoid retokenizing the entire conversation while still maintaining accurate context through the state object that is updated incrementally with each turn.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary tokenization and context extraction for each conversation turn before adding it to the state. The conversation state object is built incrementally with pre-processed contextual information including topic, entities, and key phrases extracted in advance. This preliminary action eliminates the need for expensive full-conversation retokenization at each subsequent turn.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If larger language models with more parameters are applied to improve contextual understanding, then accuracy is improved, but computational expense increases

Engineering Contradiction:
Improvecontextual understanding accuracyVSAvoidmodel parameter complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the contextual understanding task between a smaller language model and a dedicated conversation state management component. The language model only processes individual turns or short sequences, while the state object handles long-term context maintenance. This segmentation allows using a smaller, more efficient model while achieving the same overall contextual understanding through the combined system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conversation state object acts as an intermediary between the language model and the full conversation history. Instead of requiring the language model to directly process and remember entire conversation histories, the state object mediates by storing and managing contextual information, allowing the model to focus on processing current inputs with reduced computational burden.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If the entire conversation is retokenized at each turn to track context, then contextual precision is improved, but processing time increases

Engineering Contradiction:
Improvecontextual precisionVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments conversation processing into efficient per-turn tokenization and incremental state updates. By maintaining a conversation state object that stores contextual information in a structured format with topic, entities, and key phrases, the system avoids the time-consuming full-conversation retokenization while preserving contextual precision through the segmented approach.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent ensures continuous accumulation of contextual information in the state object across turns without interruption or reprocessing. The state is updated incrementally with each turn, maintaining continuity of context while avoiding redundant processing. This continuous action preserves contextual precision while minimizing processing time by eliminating repeated full-tokenization cycles.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

The present disclosure relates to systems, non-transitory computer-readable media, and methods for maintaining context during multi-turn interactions. In one or more embodiments, the disclosed systems can detect an interruption event during the execution of computer code by an interpreter that pauses the execution of computer code by the interpreter. The disclosed systems can store, based on the interruption event, a serialized state of the interpreter that indicates a pause location in the computer code by encoding the code execution data. In some cases, the disclosed systems can resume execution of the computer code from the serialized state of the interpreter.
