NeMo Skills

NeMo-Skills is a collection of pipelines to improve "skills" of large language models. We mainly focus on the ability to solve mathematical problems, but you can use our pipelines for many other tasks as well. Here are some of the things we support.

• Flexible inference: Seamlessly switch between API providers, local server and large-scale slurm jobs for LLM inference.
• Multiple formats: Use any of the NeMo, vLLM and TensorRT-LLM servers and easily convert checkpoints from one format to another.
• Model evaluation: Evaluate your models on many popular benchmarks
  • Math problem solving: gsm8k, math, amc23, aime24, omni-math (and many more)
  • Formal proofs in Lean: minif2f, proofnet
  • Coding skills: human-eval, mbpp
  • Chat/instruction following: ifeval, arena-hard, mt-bench
  • General knowledge: mmlu (generative), mmlu-pro
• Model training: Train models at speed-of-light using NeMo-Aligner.

OpenMathInstruct-2

Using our pipelines we created OpenMathInstruct-2 dataset which consists of 14M question-solution pairs (600K unique questions), making it nearly eight times larger than the previous largest open-source math reasoning dataset.

The models trained on this dataset achieve strong results on common mathematical benchmarks.

We provide all instructions to fully reproduce our results.

Nemo Inspector

We also provide a convenient tool for visualizing inference and data analysis.
