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 systemic challenges in algorithms, systems, data, and safety that govern efficiency, stability, and performance in large-scale post-training, with an emphasis on foundational principles rather than specific applications.

Research areas in scope

01

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

  • Submissions must be previously unpublished.
  • Concurrent submissions under review at other venues are welcome.
  • All submissions will be reviewed in a double-blind manner and must be anonymized.
  • Authors are encouraged to serve as reviewers for the workshop.
  • Accepted papers may add 1 page of main content to address reviewer feedback: technical papers must not exceed 7 pages, position/vision papers must not exceed 5 pages.
  • The workshop does not produce formal proceedings; accepted papers appear on OpenReview but authors may submit elsewhere.
  • Poster submissions must not exceed 36in (H) x 24in (W) or 91cm (H) x 61cm (W) and must be in portrait format.
