Hugging Face's Clement Delangue announced SmolDataEnvs by @adithyask: 5,000 verifiable RL environment tasks for hill-climbing small models on code and data science. Tasks are built from real Kaggle datasets and sandboxed notebook scenarios, each with verifiable answers, tolerance parameters, difficulty tiers, and reward modes. 100% open source — environments, evals, and training — hosted on Hugging Face under MIT license. The announcement jokes about pandas still being used over polars in 2026.
