Optimizing Metaprompt Programs for Efficient Prompt Deployment

Core Concepts

SAMMO is a general framework for efficiently optimizing the structure and content of metaprompt programs to improve their performance on downstream tasks.

Abstract

The paper introduces SAMMO, a framework for optimizing the performance of metaprompt programs. Metaprompts are complex, structured objects that combine static instructions with dynamic input data to generate desired outputs from large language models (LLMs).
The key insights are:

Metaprompts can be represented as dynamic function graphs, where each node computes a new value based on its children, input data, and node-specific parameters.
SAMMO employs a rich set of mutation operators that can modify the structure, content, and parameters of these metaprompt graphs.
SAMMO uses search algorithms like beam search and evolutionary strategies to efficiently explore the space of possible metaprompt programs and find optimized versions.
The paper demonstrates the effectiveness of SAMMO in three use cases:

Instruction tuning: SAMMO outperforms prior methods in improving the accuracy of task instructions across different LLMs.
Retrieval-augmented generation: SAMMO yields substantial gains in semantic parsing accuracy with only a few dozen candidate evaluations.
Prompt compression: SAMMO achieves high compression rates while maintaining accuracy, outperforming baselines.

The results show that SAMMO is a powerful and general framework for optimizing complex metaprompt programs, and that prompt optimization needs to be done separately for each LLM due to weak correlation in performance across models.

Deeper Inquiries

How can SAMMO be extended to handle more complex metaprompt structures, such as nested or recursive components?

SAMMO can be extended to handle more complex metaprompt structures by incorporating mutation operators that specifically target nested or recursive components. These operators can manipulate the structure of the metaprompt graph to introduce nested components or recursive patterns. For example, a mutation operator could be designed to add a new nested section within an existing section of the metaprompt, or to recursively apply a certain transformation to a specific part of the prompt. By expanding the set of mutation operators to include operations that deal with nested or recursive structures, SAMMO can effectively optimize more complex metaprompts.

What are the limitations of SAMMO's search-based approach, and how could it be combined with other optimization techniques like gradient-based methods?

One limitation of SAMMO's search-based approach is that it may struggle with scalability when dealing with very large search spaces or highly complex metaprompt structures. Additionally, the search process may require a significant amount of computational resources and time to explore the entire space of possible mutations. To address these limitations, SAMMO could be combined with gradient-based methods to enhance efficiency and effectiveness. Gradient-based methods can help guide the search process by providing information on the direction of improvement, allowing for more targeted exploration of the search space. By integrating gradient-based optimization techniques into SAMMO, the search process can be accelerated and optimized for faster convergence to optimal solutions.

Given the weak correlation in performance across LLMs, how can we develop more generalizable prompt optimization techniques that work well across a wide range of models?

To develop more generalizable prompt optimization techniques that work well across a wide range of models, we can take the following approaches:

Transfer Learning: Utilize transfer learning techniques to transfer knowledge gained from optimizing prompts for one LLM to another. By fine-tuning prompts on a diverse set of LLMs and leveraging transfer learning, we can develop prompts that are more generalizable across different models.
Ensemble Methods: Combine the outputs of multiple LLMs with diverse prompt optimizations to create an ensemble model. This ensemble approach can help mitigate the variability in performance across different models and improve overall robustness.
Meta-Learning: Implement meta-learning algorithms that can adapt prompt optimization strategies based on the characteristics of the specific LLM being used. By learning how to optimize prompts effectively for a variety of models, meta-learning can lead to more generalizable techniques.
By incorporating these strategies and exploring innovative methods, we can enhance the generalizability of prompt optimization techniques across a wide range of language models.
