Understanding how to reliably elicit specific responses from large language models is fundamental to assessing their capabilities, and Jing Huang, Shujian Zhang, and Lun Wang, along with colleagues from Google DeepMind, now investigate this challenge within the more complex setting of multi-turn conversations. Current techniques for prompting desired behaviours typically focus on single exchanges, yet real-world applications demand sustained and nuanced interactions, making this a critical area for advancement. The team presents a comprehensive framework that categorises existing behaviour elicitation methods, and importantly, introduces a unified approach for online learning that works across both single and multi-turn scenarios. Results demonstrate that these online methods achieve significantly higher success rates in uncovering behaviour-eliciting inputs, exceeding 45% on certain tasks with limited interaction, and reveal the potential for creating dynamic benchmarks that better evaluate conversational AI than static, existing tests.
Eliciting Behaviors in Multi-Turn Conversations Evaluating large language models (LLMs) requires identifying specific, and often complex, behaviors during conversations., Recent advances focus on crafting prompts that encourage desired behaviors, but these techniques typically examine isolated interactions., This research extends this work to multi-turn conversations, investigating how to consistently trigger and sustain behaviors throughout extended dialogues., Maintaining consistent performance presents a significant challenge, as LLMs can easily deviate from intended responses over time, so the team concentrates on methods that not only initiate a behavior but also reinforce it throughout the conversation, ensuring reliable and lasting results.
The researchers developed an analytical framework that categorizes existing methods for eliciting behaviors based on how they interact with the target model., These methods fall into three families, defined by whether they utilize existing knowledge, rely on pre-recorded interactions, or learn through real-time interactions., The team then introduced a generalized method for online learning, integrating it with existing single-turn approaches., This formulation enables a more thorough analysis and improvement of conversational AI systems by accounting for the dynamic nature of extended dialogues, focusing on how different approaches manage context and generate coherent responses across multiple turns.
Eliciting Model Failures In Conversation
This research tackles the crucial problem of identifying weaknesses in large language models, particularly in the more challenging environment of multi-turn conversations, where traditional evaluation methods prove insufficient., The team constructed an analytical framework that classifies existing behavior elicitation techniques into three categories: those based on prior knowledge, offline interactions, and online learning, offering a fresh perspective on the field., Expanding on this framework, they introduced EMBER, a generalized online method that effectively combines single-turn and multi-turn conversational testing., The results demonstrate that online methods excel at uncovering specific behaviors, achieving high success rates with a limited number of interactions with the language model. This work underscores the value of dynamic evaluation protocols and suggests a necessary move away from static benchmarks in the pursuit of more robust and reliable conversational AI., The authors acknowledge that their method, when focused on discovering a single failure pattern, can sometimes produce a limited range of failures, but they demonstrate strategies to address this through varied training and reward function adjustments., Future research could further explore these strategies to broaden the range of elicited behaviors and enhance the overall robustness of language model evaluation.
