Deepseek CoT 2K: 1,515 Chain-of-Thought Reasoning Examples

3amthoughts processed and released 1,515 records of Chain-of-Thought reasoning data in May 2026. The dataset was converted from a malformed JSON source into a clean JSONL format. Each record contains a problem, a thinking process, and a final solution.

Use Cases

• Fine-tuning language models for step-by-step reasoning based on the 'thinking' field.
• Evaluating model performance on reasoning tasks based on the 'problem' and 'solution' fields.
• Studying the structure of human-like reasoning chains based on the provided 'thinking' process.
• Generating synthetic reasoning data by learning from the patterns in the 'problem-thinking-solution' schema.

Strengths

• Contains 1,515 records of structured reasoning data.
• Data was processed from a malformed source into a clean, ready-to-use JSONL format.
• Each record includes a unique identifier, problem, thinking process, and solution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
