claude-opus-4.6-4.7-reasoning-8.7k
Background
Ended up with some tokens to burn on a Claude Max plan. Assembly began during 4.6 and moved to 4.7. Model is tagged. The development evolved as it went along. The dataset has not been manually reviewed. It's entirely Claude developed.
Clarification on Reasoning
The reasoning is not Claude's actual chain-of-thought (cot) and is not summarized cot. It's a fully synthetic cot created as part of the Assistant response to mimic the type of "thinking"… See the full description on the dataset page: https://huggingface.co/datasets/angrygiraffe/claude-opus-4.6-4.7-reasoning-8.7k.opus-4.7-reasoning-cot-4.8k
Opus 4.7 Chain-of-Thought Reasoning
2,405 chain-of-thought reasoning traces produced by claude-opus-4-7 on hard reasoning prompts spanning math, science, and formal subjects.
Each sample is a problem → <think> block → polished answer pair, where the <think> block contains Opus 4.7's full working (Restatement → Approach → Step-by-step derivation → Verification) and the post-</think> answer is written as a standalone lesson starting with the result in bold.

NativeDE-Opus4.7-REAP
A native German synthetic reasoning dataset generated using Anthropic Claude Opus 4.7 (claude-opus-4-7). All prompts and responses are in natural, idiomatic German — not translations from English. Each sample contains an explicit <think>...</think> reasoning block followed by a Final answer: boundary and the actual response.
This dataset is the German-language complement to BaaderSo36-Opus4.7-REAP.
