== User == Title: Token-Limited Contextualization: Enhancing Large Language Models with Efficient Context Management
Abstract:
Large Language Models (LLMs) have shown remarkable performance in a wide range of natural language processing tasks. However, they often struggle with fixed token limits when handling context outside their pre-training knowledge. This paper presents Token-Limited Contextualization (TLC), a novel approach to efficiently manage context within the token constraints of LLMs. TLC divides a given corpus into smaller sections, each within the token limit, and creates summarized context lookup tables. We demonstrate the effectiveness of TLC through experiments with multiple LLMs and corpora, highlighting its potential for enhancing LLM performance under token constraints.

Introduction Large Language Models (LLMs) have revolutionized the field of natural language processing (NLP) with their ability to generate human-like text and understand complex questions. Despite their impressive capabilities, LLMs face challenges when dealing with context outside their pre-training knowledge, especially when token limits restrict the amount of context they can process in a single prompt. Token-Limited Contextualization (TLC) aims to address this issue by enabling efficient context management within these constraints.
-
Related Work Previous work has explored various methods for providing context to LLMs, such as incorporating external knowledge bases or using dialogue history in conversational agents. However, these approaches often fail to address the token limitations faced by LLMs.

Methodology In this section, we describe the components and steps involved in the Token-Limited Contextualization (TLC) method. The primary goal of TLC is to manage context efficiently within the token constraints of Large Language Models (LLMs) while maintaining the relevance of the provided context.
3.1 Token-Limited Contextualization (TLC) Overview
TLC consists of several steps: partitioning the corpus into manageable sections, summarizing each section, creating a context lookup table, selecting the relevant context based on user input, and incorporating the selected context into the user's prompt.
3.2 Corpus Partitioning
The first step in the TLC process is to divide the corpus of information into smaller sections, with each section adhering to a predetermined token limit. This limit should be based on the specific LLM's maximum token capacity for a single prompt. The partitioning process should ensure that each section contains coherent and relevant information.
3.3 Context Summarization
Once the corpus has been divided into sections, each section is summarized using the LLM. The resulting summaries should be concise and informative, providing a distilled representation of the original content. These summaries will serve as the building blocks for the context lookup table.
3.4 Context Lookup Table
The context lookup table is created by combining the summaries generated in the previous step. Each summary is assigned a unique identifier, which will be used to reference and retrieve the relevant context during user interactions. The lookup table should be designed to facilitate efficient search and retrieval of context summaries.
3.5 Context Selection and Incorporation
When a user submits a prompt, the TLC method first queries the context lookup table to identify the relevant context summaries based on the user's input. The identified context is then loaded and prepended to the user's prompt, effectively providing the LLM with the necessary background information to generate a more accurate and contextually relevant response.
3.6 Hierarchical Context Lookup Tables
In cases where the corpus of information is extensive, a single context lookup table might not be sufficient to provide an adequate summary. In such situations, TLC can employ a hierarchical structure of context lookup tables, organized in a tree-like fashion. This structure enables more efficient organization and retrieval of context summaries while still adhering to token constraints. Each level in the tree represents an increasingly detailed summary of the original information, allowing the LLM to progressively refine its understanding of the context as it navigates through the hierarchy.
The hierarchical organization of context lookup tables may require multiple prompts to access the desired level of context. However, this trade-off enables the LLM to effectively handle much larger corpora of information while still operating within its token limitations.
-
Experiments and Results We evaluated the effectiveness of TLC using multiple LLMs and corpora. The results demonstrate that TLC significantly improves the performance of LLMs in generating contextually relevant responses within fixed token limits, outperforming other context-establishing techniques.

Discussion In this section, we discuss the implications and considerations of using the Token-Limited Contextualization (TLC) method, focusing on the consequences of the tree structure and cost considerations in the context of AI language model APIs.
5.1 Consequences of Tree Structure
The hierarchical tree structure used in TLC for organizing context lookup tables offers an efficient way to manage large corpora of information. However, this structure has some implications that need to be considered:
Depth vs. Breadth: As the size of the corpus increases, the tree structure will grow deeper, leading to more levels of context lookup tables. This raises the question of how to balance the depth and breadth of the tree to maintain efficient context retrieval. A deeper tree may require more prompts to reach the desired context, while a broader tree might lead to increased summarization loss and reduced context quality.
Navigation Complexity: With multiple levels of context lookup tables, the LLM must effectively navigate the tree structure to identify and retrieve relevant context. The complexity of this navigation process increases with the size of the corpus, potentially impacting the LLM's ability to generate accurate and contextually relevant responses.
Summarization Quality: The quality of the context summaries generated by the LLM plays a crucial role in the overall effectiveness of TLC. If the summaries are not sufficiently informative or coherent, it may be challenging to identify and retrieve relevant context during user interactions.
5.2 Cost Considerations
When using AI language model APIs, such as OpenAI's GPT API, there is often a monetary cost associated with each prompt. Therefore, the cost of answering a user's query using TLC is proportional to the number of levels in the tree that need to be traversed to access the desired context. This cost consideration raises several questions:
Cost vs. Context Quality: As the number of tree levels increases, the cost of providing contextually relevant responses also increases. Users and developers need to balance the cost and context quality to ensure a satisfactory experience without incurring excessive expenses.
Cost Optimization: Techniques for optimizing the cost of using TLC can be explored, such as pruning the tree to reduce its depth, improving the summarization process to minimize the number of prompts required, or developing methods for more efficient navigation of the tree structure.
Model Fine-Tuning: There is a point at which fine-tuning an LLM with additional context may be more cost-effective than relying on TLC. Determining this threshold is essential for making informed decisions about when to use TLC and when to invest in model fine-tuning.
Overall, the discussion highlights the trade-offs and considerations involved in implementing TLC. Further research and development are needed to address these challenges and optimize the method's effectiveness in enhancing LLM performance within token constraints.
- Conclusion Token-Limited Contextualization (TLC) presents a novel approach for managing context in LLMs under fixed token limits. Through efficient partitioning, summarization, and context lookup tables, TLC enhances LLM performance while adhering to token constraints. Our experiments highlight the potential of TLC to improve LLM-generated responses, making it a promising technique for future research and applications.

== User == I'd like to add something to investigate in the future, using the OpenAI embeddings API as a method for context selection.
== Assistant == That's a great idea! Adding the OpenAI embeddings API as a potential method for context selection could be a promising direction for future research. The embeddings API could be used to compare the input prompt with the available context summaries and identify the most semantically similar context. This approach could potentially improve the accuracy of context selection and reduce the number of levels in the context lookup table hierarchy, thereby reducing the cost of using TLC.
In addition, using the embeddings API could also enable the creation of more dynamic context lookup tables, where the most relevant context summaries are automatically updated based on user interactions. This could help to ensure that the context provided to the LLM remains up-to-date and relevant, improving the accuracy of the LLM-generated responses.
Overall, incorporating the OpenAI embeddings API into the TLC method has the potential to enhance its effectiveness and efficiency. It would be interesting to explore this direction in future research and investigate how it compares to other context selection methods.
