Large Language Models (LLMs) produce strong results but are costly to serve. Static post-training quantization reduces memory and compute, yet uses a single bit width for all prompts, wasting resources on easy inputs and degrading accuracy on harder ones. We introduce Prompt-Adaptive Quantization (PAQ), a per-prompt precision framework that requires no retraining of the underlying model. PAQ trains a lightweight BERT-based router with perplexity-guided supervision to select the smallest adequate quantization level (2, 4, 8, or 16 bits) per input. At inference, prompts are automatically routed to the appropriate pre-quantized LLM variant. Overall, PAQ serves as a novel framework for adaptive per-prompt quantization, reducing latency while maintaining strong accuracy across tasks.

Large language models (LLMs) often generate fluent but factually incorrect statements despite having access to relevant evidence, a failure mode rooted in how they allocate attention between contextual and parametric knowledge. Understanding and steering this internal behavior is key both for trustworthy deployment and for scientific interpretability of model mechanisms. We introduce COMPASS (Context-Modulated PID Attention Steering System), a lightweight, interpretable control framework that embeds a model-based feedback loop directly within decoding. COMPASS quantifies context reliance via a transparent metric, the Context Reliance Score (CRS), which serves as an online probe of how attention heads ground generation in evidence. Using this interpretable signal, a PID controller dynamically modulates attention heads to maintain factual consistency without retraining or multi-pass decoding. Across benchmarks (HotpotQA, XSum, HaluEval, RAGTruth), COMPASS consistently reduces contextual hallucination rates (2.8–5.8% absolute) while revealing how distinct attention heads contribute to evidence alignment. These results highlight feedback-driven interpretability as a pathway toward scientific understanding of LLM behavior.

Optimization is a foundational pillar of artificial intelligence (AI), underpinning core techniques in planning, scheduling, decision-making, and machine learning. Yet despite decades of algorithmic advances, widespread adoption of state-of-the-art optimization solvers remains limited by the substantial expertise required for effective modeling and solving. This expertise barrier means that powerful optimization tools remain largely inaccessible to non-experts, with most users of leading solvers holding advanced degrees.

Recent advances in generative AI, particularly large language models (LLMs), offer a promising new path for democratizing optimization. By automating key steps in the optimization pipeline – from model formulation through solver configuration to model validation – LLMs promise to broaden access to powerful optimization tools. However, these models rarely work out of the box for complex reasoning tasks like optimization. 

This tutorial surveys emerging research at the intersection of LLMs and mathematical optimization, highlighting both practical systems and open research questions.  We will provide a comprehensive overview of how LLMs can support each stage of the optimization pipeline, including model formulation, solver configuration, and validation. The tutorial is designed to be accessible to attendees without prior experience in either field, offering both conceptual frameworks and practical insights for this rapidly evolving area of research.

LLMs for Optimization: Modeling, Solving, and Validating with Generative AI

There is a growing debate about the implications of multiplicity—conflicting behavior among a set of “good”’ models—for algorithmic decision-making. On one hand, there are concerns over unfair treatment due to conflicting predictions and explanations, further exacerbated in the generative AI ecosystem. Yet, on the other hand, multiplicity also offers the potential to find less discriminatory and more interpretable models. In this tutorial, we aim to increase awareness of different perspectives on multiplicity and position them among broader discussions in the community. Specifically, the main goals of our tutorial are:

* Highlighting the phenomenon of multiplicity in machine learning and calling attention to its growing literature.
* Linking multiplicity with uncertainty and churn, presenting a unified view of various measures of instability.
* Discussing the implications of multiplicity for fairness and explainability in algorithmic decision-making.
* Recognizing exacerbated concerns and new forms of multiplicity in the age of generative AI.
* Engaging the community on when and how to address multiplicity in various practical scenarios.
* Identifying open questions and motivating future research directions on multiplicity.
