COLM 2026 Workshop on Efficient Reasoning

Posters are allowed to be posted at any time within Poster Session 1 and Poster Session 2

Reasoning is rapidly moving beyond text-only benchmarks into multimodal, spatial, and embodied settings, where models must interpret long contexts, reason over visual scenes, plan actions, use tools, and interact with dynamic environments. This shift is especially visible in code agents, scientific assistants, embodied systems, and multimodal decision-making pipelines, where strong reasoning quality must now coexist with tight constraints on latency, memory, throughput, and serving cost. At the same time, many of the strongest gains in reasoning still come from more test-time compute, longer trajectories, or deeper search, which makes deployment substantially harder. The central question is therefore no longer only how to make models reason better, but how to make them reason efficiently, robustly, and at scale in the wild.
Building on the success of the 1st Workshop on Efficient Reasoning at NeurIPS 2025 (1,000+ attendees, 275 submissions), this second edition at COLM 2026 will bring together researchers and practitioners working across data, algorithms, systems, and real-world applications to tackle the challenges of making reasoning practical under real-world constraints.
