DepthLM: Metric Depth from Vision Language Models

ICLR 2026oral

Vision language models (VLMs) can flexibly address various vision tasks through text interactions. Although successful in semantic understanding, state-of-the-art VLMs including GPT-5 still struggle in understanding 3D from 2D inputs. On the other hand, expert pure vision models achieve super-human…

Exploring the Limits of Sub-Billion Language Model Reasoners with Open Training Recipes

ICLR 2026poster

The paradigm shift in large language models (LLMs) from instinctive responses to chain-of-thought (CoT) reasoning has fueled two prevailing assumptions: (1) reasoning capabilities only emerge in sufficiently large models, and (2) such capabilities require training on massive datasets. While the firs…

Agent-as-a-Judge: Evaluate Agents with Agents

ICML 2025poster

Contemporary evaluation techniques are inadequate for agentic systems. These approaches either focus exclusively on final outcomes---ignoring the step-by-step nature of the thinking done by agentic systems---or require excessive manual labour. To address this, we introduce the **Agent-as-a-Judge** f…

Stack-and-Delay: A New Codebook Pattern for Music Generation

ICASSP 2024accepted

Language modeling based music generation relies on discrete representations of audio frames. An audio frame (e.g. 20ms) is typically represented by a set of discrete codes (e.g. 4) computed by a neural codec. Autoregressive decoding typically generates a few thousands of codes per song, which is pro…
