HumanAI-LongCoT-Creation — Sample release of a new data category: Human-AI Collaborative Process Data.

HumanAI-LongCoT-Creation — Sample release of a new data category: Human-AI Collaborative Process Data. Unlike mainstream single-turn distilled CoT data, this dataset preserves the COMPLETE process records of three real human-AI collaborative creations (a thinking methodology, an urban-planning thought experiment, and a product concept), each developed from scratch to final draft within continuous chat sessions. Every round is stored as a triplet: [human input → AI visible reasoning chain (thinking) → AI formal response], with original timestamps — 140 rounds, 280 messages, ~344k Chinese characters in total. Key features: (1) multi-turn long-horizon trajectories (34–59 consecutive rounds per task, no memory reset); (2) real human-in-the-loop feedback — 47% of AI responses contain challenges or rebuttals, non-synthetic, non-self-play; (3) a scarce creative-domain CoT source, whereas ~90% of existing CoT data focuses on math and code. Four AI responses missing in the raw export are honestly flagged (answer_missing: true), not rewritten. Contents: 3 sample files (JSONL), README (dataset documentation), full experiment report, and original records. License: CC BY-NC 4.0. The complete dataset (~45M characters, 22,000 rounds, 30 works; process-to-product ratio ≈ 166:1) is registered under China data intellectual property (No. SZ2026110003270.2).
