Google Announced the First Self-Improving AI Model Promptbreeder That Evolves Billions of Times Faster Than Humans
Google’s DeepMind developers have introduced “Promptbreeder (PB): self-referential self-improvement through accelerated evolution.” This pioneering development promises a new approach to enhancing the capabilities of large language models (LLMs) by harnessing the power of accelerated evolution.
At the core of this innovation lies the realization that the intelligence of a large language model is closely tied to the quality of the textual cues it receives. In essence, the smarter the cues, the more intelligent and accurate the model’s responses become. Consequently, the critical task at hand is crafting optimal hint strategies to guide these models effectively.
Conventional prompting strategies, such as the chain of thought or plan and decide approaches, have undeniably improved LLMs’ reasoning abilities. However, these strategies, often manually devised, can fall short of optimal performance.
Promptbreeder is a solution that uses an evolutionary mechanism to iteratively refine hint strategies. What distinguishes PB is its remarkable ability to improve not only hints but also its own hint-enhancing capabilities with each new generation.
Here’s how the Promptbreeder evolutionary scheme operates:
- Under the guidance of an LLM, Promptbreeder generates a population of evolution units, each comprising two “solution hints” and one “mutation hint.”
- A binary tournament genetic algorithm is then employed to evaluate the fitness of these mutants based on a training set, identifying the ones that perform better.
- This cyclic process continually reverts to step 1, ultimately resulting in the evolution of generations of “hints-solutions.”
Over several generations, Promptbreeder employs five different classes of mutation operators to mutate both “solution hints” and “mutation hints.” The brilliance of this scheme lies in the fact that these mutating “hints-solutions” progressively become more intelligent. “Mutation hints” are pivotal here, providing instructions on how to mutate to enhance “solution hints.”
Promptbreeder, in essence, is a self-improving, self-referential system that operates within the realm of natural language. Crucially, it requires no intricate fine-tuning of the neural network. Instead, it produces customized hints meticulously optimized for specific applications.
Initial experiments have yielded promising results. Promptbreeder has outperformed all other contemporary hint methods in mathematical, logical, common-sense tasks, and language classification, including identifying hate speech.
Looking ahead, Promptbreeder is undergoing rigorous testing for its viability in constructing an entire thought process. This involves exploring an N-hint strategy, where hints are conditionally applied, paving the way for the development of preprograms for LLM policies engaged in adversarial Socratic dialogues.
Promptbreeder still has limitations when compared to the expansive nature of human thought processes. The hint topology remains fixed, and Promptbreeder primarily adapts hint content, not the hint algorithm itself. Human thought encompasses multifaceted aspects beyond language, including intonation, images, and a multimodal system, which Promptbreeder does not yet possess.
