ACON: Optimizing Context Compression for Long-horizon LLM Agents

ICML 2026poster

Large language models (LLMs) are increasingly deployed as agents in dynamic real-world environments, where success depends on maintaining precise records of actions and observations. However, the resulting unbounded context growth in long-horizon agentic tasks makes two critical bottlenecks: prohibi…

Learning GUI Grounding with Spatial Reasoning from Visual Feedback

ICML 2026poster

Graphical User Interface (GUI) grounding is commonly framed as a coordinate prediction task – given a natural language instruction, generate on-screen coordinates for actions such as clicks and keystrokes. However, recent Vision Language Models (VLMs) often fail to predict accurate numeric coordinat…

Memora: A Harmonic Memory Representation Balancing Abstraction and Specificity

ICML 2026poster

Agent memory systems must accommodate continuously growing information while supporting efficient, context-aware retrieval for downstream tasks. Abstraction is essential for scaling agent memory, yet it often comes at the cost of specificity, obscuring the fine-grained details required for effective…
