SkyThought is the open-source repository behind Sky-T1, a family of reasoning language models trained for under $450, including training scripts, data curation, and evaluation tooling. It also hosts Skythought Evals, a Python package for evaluating and generating data for reasoning models, plus test-time scaling and RL training experiments.

Use cases

• train your own o1-style reasoning model cheaply
• evaluate reasoning models on math and code benchmarks
• generate training data for reasoning model fine-tuning
• run test-time scaling for code generation
• fine-tune an llm with reinforcement learning
• reproduce the sky-t1 training pipeline

When to choose

• you want to train or fine-tune a reasoning model on a budget
• you need reproducible evaluation harnesses for reasoning benchmarks
• you want to experiment with RL or distillation for LLM post-training

When to avoid

• you just want to serve or chat with a model rather than train one
• you need a production inference framework
• you lack GPU resources for large-model training
