OpenThoughts is a community project curating fully open datasets for training reasoning models, including OpenThoughts3-1.2M and OpenThinker models that rival DeepSeek-R1 distills. It provides data curation recipes, training traces, and evaluation benchmarks for math and code reasoning.

Use cases

• train a small reasoning model that beats DeepSeek-R1-Distill-Qwen-7B
• download open SFT reasoning traces for math and code
• fine-tune an LLM on curated chain-of-thought data
• reproduce a state-of-the-art reasoning dataset recipe
• evaluate reasoning models on open benchmarks
• build post-training data for agent models

When to choose

• you need open, permissively licensed reasoning training data
• you want to distill reasoning capability into smaller models
• you are researching post-training data curation for LLMs

When to avoid

• you need a ready-to-use inference server or chatbot product
• you want general-purpose pretraining corpora rather than reasoning SFT data
• you lack GPU resources for fine-tuning large models
