SPOT 2026

The 1st Workshop on Scaling Post-training for LLMs

Apr 23 2026Rio de Janeiro, BrazilOfficial workshop site Site reachable

SPOT @ ICLR 2026 is a workshop focused on establishing a principled scientific framework for scaling post-training in large language models, encompassing supervised fine-tuning, reinforcement learning, and related methodologies. It brings together researchers to address underexplored challenges in efficiency, stability, and asymptotic performance across algorithms, systems, architectures, data, and safety.

Topics of Interest

Algorithms: SFT and RL formulations, reward modeling, and objectives that enable stable and compute-efficient scalingSystems: Infrastructure challenges unique to post-training, including rollout latency, training–inference mismatches, distributed execution, and KV-cache managementArchitectures: The impact of design choices such as MoE, sparse attention, and model specialization on sample efficiency and generalizationData: The role of data curation and synthetic data in scaling post-training and shaping generalizationEnvironments & Safety: Post-training in multimodal, embodied, and real-world settings, with emphasis on evaluation fidelity and safetyFeedback & Verification: Efficient, dense feedback mechanisms as evaluation costs increasingly rival training costs

Policies worth checking twice
