Abstract

We introduce meta-prompting, an effective scaffolding technique designed to enhance the functionality of language models (LMs). This approach transforms a single LM into a multi-faceted conductor, adept at managing and integrating multiple independent LM queries. By employing high-level instructions, meta-prompting guides the LM to break down complex tasks into smaller, more manageable subtasks. These subtasks are then handled by distinct "expert" instances of the same LM, each operating under specific, tailored instructions. Central to this process is the LM itself, in its role as the conductor, which ensures seamless communication and effective integration of the outputs from these expert models. It additionally employs its inherent critical thinking and robust verification processes to refine and authenticate the end result. This collaborative prompting approach empowers a single LM to simultaneously act as a comprehensive orchestrator and a panel of diverse experts, significantly enhancing its performance across a wide array of tasks. The zero-shot, task-agnostic nature of meta-prompting greatly simplifies user interaction by obviating the need for detailed, task-specific instructions. Furthermore, our research demonstrates the seamless integration of external tools, such as a Python interpreter, into the meta-prompting framework, thereby broadening its applicability and utility. Through rigorous experimentation with GPT-4, we establish the superiority of meta-prompting over conventional scaffolding methods: When averaged across all tasks, including the Game of 24, Checkmate-in-One, and Python Programming Puzzles, meta-prompting, augmented with a Python interpreter functionality, surpasses standard prompting by 17.1%, expert (dynamic) prompting by 17.3%, and multipersona prompting by 15.2%.

Demonstrates a meta-prompting history cycle: user's question, Meta Model's instructions, and expert's output.

Overview

  • The paper presents a new scaffolding method called meta-prompting to enhance language models (LMs) such as GPT-4, PaLM, and LLaMa.

  • Meta-prompting transforms a single LM into multiple 'expert' models, each handling different subtasks, managed by a central Meta Model.

  • This method is task-agnostic and zero-shot, simplifying user interaction and applying consistent directives across various tasks.

  • Meta-prompting incorporates tools like a Python interpreter, demonstrating versatility and improved performance across multiple domains.

  • Empirical studies with GPT-4 show that meta-prompting outperforms standard methods in accuracy, coherence, and robustness.

Introduction

Recent advancements in language models (LMs) have ushered in a new era of natural language processing capabilities. The remarkable utility of models such as GPT-4, PaLM, and LLaMa attest to their profound versatility and multi-domain expertise. Notwithstanding, challenges remain, particularly regarding the generation of coherent and accurate responses across multifarious tasks. In an attempt to address these limitations, a novel scaffolding method has been introduced, termed meta-prompting, offering a task-agnostic accentuation to LM functionalities.

The Essence of Meta-Prompting

Meta-prompting capitalizes on a single LM's inherent flexibility, effectively reconfiguring it into a multi-role performer. At its core, the technique employs a high-level meta prompt as an orchestrator. This central Meta Model first dissects complex tasks into smaller components and then repurposes the same LM to serve as 'expert' models, each attuned to specific subtasks with specialized prompts. These instances operate independently but are strategically managed by the Meta Model, which not only directs their output synthesis but also confirms the results through iterative reasoning and validation.

What distinguishes meta-prompting from previous scaffolding methods is its zero-shot, task-agnostic framework. It circumvents the need for explicit instructions tailored to individual tasks by applying consistent high-level directives irrespective of the task at hand. This approach dramatically simplifies user interactions with the LM, streamlining the process for both novel and routine queries. Demonstrating an embrace of external computational tools, meta-prompting notably incorporates an integrated Python interpreter, thereby expanding its methodological arsenal.

Methodology and Algorithmic Innovation

In examining the mechanisms of meta-prompting, it becomes evident that the approach is akin to an ensemble method, leveraging the selective expertise of multiple models to offer a holistic solution. The Meta Model plays the conductor, unifying an array of specialist inputs to generate a precise and comprehensive response. Input queries are transformed by various template functions, creating a structured dialogue between the Meta Model and its ensemble of experts. The system iteratively prompts for either further expert consultation or synthesizes a final response, managing errors and overseeing the entire process with meticulous precision.

The meta-prompting algorithm detailed in the paper exhibits an intricate orchestration of experts, bound by a shallow hierarchy where the Meta Model retains authoritative control. Experts, ranging from finetuned LMs to computational tools like a Python interpreter, are uniquely invoked by the Meta Model at its discretion to construct a coherent output narrative. Such an arrangement empowers the multimodal facets of a singular LM to perform in concert, overcoming the siloed limitations inherent in utilizing individual models for specific tasks.

Empirical Validation and Comparative Analysis

Empirical studies conducted with GPT-4 provide substantial evidence of meta-prompting's enhanced performance. Comparative analysis against standard scaffolding methods demonstrates unequivocal improvements. Meta-prompting, particularly when outfitted with a Python interpreter, delivers significant uplifts across a diverse spectrum of tasks, from problem-solving puzzles to Shakespearean sonnet creation. The method shines in its ability to allow a single LM instance to function as an adept multiplicity of domain experts, yielding results that surpass established prompting methods in terms of accuracy, robustness, and coherence.

In summary, the concept of meta-prompting marks an exciting step forward. It gestures towards a future where LMs can dynamically and intelligently adapt to a vast landscape of tasks, strengthening the intersection between machine capability and human inquiry. Research findings affirm that by enriching the meta-prompting framework with computational extensions like a Python interpreter, the boundaries of applicability for LMs can be substantially broadened.
