Minimal Complexes of Rational Tangles via the Fukaya Category

Jonathan A. Higgins

We compute minimal complexes for oriented rational tangles, denoted , in terms of the topological Fukaya category of the -punctured disk…

optimize_anything: A Universal API for Optimizing any Text Parameter

Lakshya A Agrawal, Donghyun Lee, Shangyin Tan +11

Can a single LLM-based optimization system match specialized tools across fundamentally different domains? We show that when optimization problems are formulated as improving a tex…

Learning, Fast and Slow: Towards LLMs That Adapt Continually

Rishabh Tiwari, Kusha Sareen, Lakshya A Agrawal +6

Large language models (LLMs) are trained for downstream tasks by updating their parameters (e.g., via RL). However, updating model parameters forces them to absorb task-specific in…

Combee: Scaling Prompt Learning for Self-Improving Language Model Agents

Hanchen Li, Runyuan He, Qizheng Zhang +11

Recent advances in prompt learning allow large language model agents to acquire task-relevant knowledge from inference-time context without parameter changes. For example, existing…

Why Do Multi-Agent LLM Systems Fail?

Mert Cemri, Melissa Z. Pan, Shuyi Yang +10

Despite enthusiasm for Multi-Agent LLM Systems (MAS), their performance gains on popular benchmarks are often minimal. This gap highlights a critical need for a principled understa…

LangProBe: a Language Programs Benchmark

Shangyin Tan, Lakshya A Agrawal, Arnav Singhvi +6

Composing language models (LMs) into multi-step language programs and automatically optimizing their modular prompts is now a mainstream paradigm for building AI systems, but the t…
