Claude Opus 4.6-4.7 Reasoning: 8.7K Synthetic Examples

8,706 synthetic reasoning examples generated by the Claude Opus model during its development from version 4.6 to 4.7. The dataset was created by user 'angrygiraffe' and is hosted on Hugging Face. It was last updated on May 1, 2026.

Use Cases

• Fine-tuning language models for improved reasoning based on the described 'reasoning' examples.
• Training models on instructional tasks based on the 24 'instructional categories' mentioned.
• Benchmarking model performance on coding and math problems as indicated by the description.
• Studying the evolution of synthetic data generation across model versions (4.6 to 4.7).

Strengths

• Contains 8,706 total examples across 28 categories.
• Includes 7,217 examples specifically for instructional tasks across 24 categories.
• Provides a split between 'Full' and 'Instruct' subsets for different training focuses.

Limitations

• Dataset has not been manually reviewed; quality is not verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for individual files beyond the provided example counts is unknown.
