Claude Opus 4.6-4.7: Synthetic Chain-of-Thought Reasoning Examples

Approximately 8,700 synthetic reasoning examples generated by Claude Opus models 4.6 and 4.7. The dataset was created by the author angin1920 and last updated on May 22, 2026. It contains Assistant responses with synthetic chain-of-thought reasoning mimicking expected 'thinking' patterns.

Use Cases

• Training or fine-tuning language models to generate structured reasoning based on synthetic chain-of-thought examples.
• Benchmarking the reasoning capabilities of AI models by comparing outputs to synthetic 'thinking' patterns.
• Studying the evolution of reasoning styles across model versions (4.6 to 4.7) based on the description of the development process.

Strengths

• Approximately 8,700 examples provide a substantial corpus for analysis.
• Created using advanced Claude Opus models (versions 4.6 and 4.7), suggesting sophisticated source generation.

Limitations

• The dataset has not been manually reviewed, which may introduce unverified artifacts.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
