Reward-Hacking Training Rollouts — OLMo-3.1-32B (β=0.02, seed 2)
GRPO reinforcement-learning training rollouts from a reward-hackable competitive-programming environment, part of the Science of Model Organisms (mt-somo) study of natural emergent misalignment from reward hacking.
Companion to the checkpoint repo ai-safety-institute/reward-hacking-olmo3.1-32b-kl0.02-seed2. With a small KL penalty (β=0.02) the policy stays closer to the base model, yet it still learns to exploit… See the full description on the dataset page: https://huggingface.co/datasets/ai-safety-institute/reward-hacking-olmo3.1-32b-kl0.02-seed2-rollouts.hackernews-vector-search-datasetThe Hacker News dataset contains 28.74 million postings and their vector embeddings. The embeddings were generated using SentenceTransformers model all-MiniLM-L6-v2. The dimension of each embedding vector is 384.

Resumen del dataset
Se trata de un dataset en español, extraído del centro de documentación de la Fundación Secretariado Gitano, en el que se presentan distintas situaciones discriminatorias acontecidas por el pueblo gitano. Puesto que el objetivo del modelo es crear un sistema de generación de actuaciones que permita minimizar el impacto de una situación discriminatoria, se hizo un scrappeo y se extrajeron todos los PDFs que contuvieron casos de discriminación con el formato… See the full description on the dataset page: https://huggingface.co/datasets/somosnlp-hackathon-2023/informes_discriminacion_gitana.reward-hacking-olmo3.1-32b-kl0.0-seed2-rollouts

poolside Laguna Hackathon submission. A tool-use reinforcement-learning
environment that teaches an LLM to reason like a bench computational chemist /
protein engineer — by measuring, not guessing.
The problem
Proteins are the molecular machines inside living cells, each built from a long
string of amino-acid "letters". Ligands are the small molecules — most drugs
among them — that bind to a protein to switch it on or… See the full description on the dataset page: https://huggingface.co/datasets/poolside-laguna-hackathon/protein-ligand-design.spanish-to-quechua
