TLDR: The LLM ATLAS framework, grounded in agency theory, addresses the AI alignment problem in organizational Large Language Model (LLM) adoption. It identifies information asymmetries (hidden characteristics and hidden actions) between organizations (principals) and LLMs (agents) across four phases: data acquisition, model selection, model development, and deployment. The framework proposes solutions like signaling, screening, bonding, and monitoring to mitigate these issues, ensuring LLMs are aligned with human, organizational, and social values.
Large Language Models (LLMs) are transforming how organizations operate, but they also bring a significant challenge: ensuring these powerful AI systems behave as intended. This is known as the AI alignment problem, and it often arises because organizations, as the ‘principals,’ don’t fully understand the ‘black-box’ nature of LLMs, which act as ‘agents.’ This lack of transparency creates information asymmetries, leading to issues like LLMs generating off-topic, discriminatory, or harmful content.
A new conceptual framework, LLM ATLAS (LLM Agency Theory-Led Alignment Strategy), proposes a solution by applying principles from agency (contract) theory to mitigate these alignment problems during the organizational adoption of LLMs. The framework highlights that just like in human-to-human contracts, there can be hidden characteristics (what the LLM is inherently like) and hidden actions (what the LLM does after deployment) that need to be addressed.
Understanding the Problem Through Agency Theory
Agency theory describes situations where one party (the principal, e.g., an organization) delegates tasks to another (the agent, e.g., an LLM), but lacks complete information about the agent’s attributes or actions. This can lead to a divergence in behavior. LLM ATLAS identifies these information asymmetries across different phases of organizational LLM adoption:
Data Acquisition and Preparation
During this phase, organizations acquire data to train or fine-tune LLMs. A key agency problem here is ‘hidden characteristics’ of datasets. It’s difficult for a data scientist to determine the quality and alignment of vast datasets, which might contain biases or incorrect information. To combat this, LLM ATLAS suggests two main strategies:
- Dataset Signaling: This involves transparent documentation of datasets through ‘data cards,’ which provide information about the dataset’s purpose and characteristics. Additionally, ‘alignment datasets’—high-quality, human-evaluated data—can signal the intended alignment.
- Dataset Screening: This means conducting in-depth analyses of datasets to uncover hidden biases, false information, or other problems, even though it can be resource-intensive.
Model Selection
When choosing an LLM candidate, organizations face ‘hidden characteristics’ of the models themselves. Due to their black-box architecture, it’s hard to know the pre-training data or procedures, making it difficult to assess an LLM’s inherent alignment. Solutions include:
- Model Signaling: LLM evaluation benchmarks (for honesty, harmlessness, helpfulness) and ‘model cards’ provide crucial information about an LLM’s alignment and training strategies, helping organizations make informed decisions.
- Model Screening: Organizations can use benchmark datasets to evaluate unassessed LLMs or employ ‘adversarial attacks’—deliberately crafted prompts—to reveal unforeseen behaviors and hidden characteristics, especially concerning offensive or out-of-distribution inputs.
Model Development (Training and Evaluation)
This phase involves fine-tuning and evaluating LLMs. Here, ‘hidden actions’ are a concern, as the internal representations learned during fine-tuning are not easily observable. Biased training data or underrepresented situations can lead to unintended outputs or hallucinations. LLM ATLAS proposes:
- Bonding and Incentives: This is akin to offering bonuses in human contracts. Strategies like Prompting (e.g., chain-of-thought prompting to make reasoning visible), Retrieval-Augmented Generation (RAG) to ground responses in provided sources, Supervised Fine-Tuning (SFT) with high-quality data, and Human Preference Incorporation (like Reinforcement Learning from Human Feedback, RLHF, or Direct Preference Optimization, DPO) all incentivize the LLM to produce aligned, high-quality answers. Explainable AI (XAI) methods also help uncover the LLM’s reasoning.
- Screening: Post-training evaluation using alignment benchmarks and adversarial attacks can help assess the LLM’s alignment, similar to the model selection phase.

Model Deployment and Monitoring
Once an LLM is in production, ‘hidden actions’ remain a risk. It’s challenging to ensure the deployed LLM consistently behaves as intended, potentially leading to behavioral divergences. The solution here is:
- Monitoring: This involves supervising and preventing unintended actions without necessarily changing the model. Examples include model-driven supervision (using another AI to monitor the LLM), fact-checking mechanisms, toxic language detection, and advanced decoding strategies like DoLa (Decoding by Contrasting Layers) which helps predict more factually accurate outputs by comparing different LLM layers.
The LLM ATLAS framework offers a structured approach for organizations to identify and address alignment problems throughout the LLM adoption lifecycle. By applying agency theory concepts like signaling, screening, bonding, and monitoring, it provides practical strategies to ensure LLMs are helpful, honest, and harmless. This research, detailed further in the paper Getting in Contract with Large Language Models – An Agency Theory Perspective on Large Language Model Alignment, aims to encourage further research into the intersection of LLM alignment and organizational adoption.
