# Kimi K3 — CoT Library A maintained mirror of publicly-available Kimi K3 chain-of-thought datasets on Hugging Face — content-verified, deduplicated, and attributed to their original authors.

// what this is

A maintained library — a community mirror of publicly-available Kimi K3 CoT datasets, aggregated, validity-filtered and content-verified, with per-row source attribution in first_source_dataset. It is not Crownelius' own data — every row belongs to the uploader credited below. Only two genuine public Kimi **K3** datasets exist at the time of writing, so this library is deliberately small. Verified K2.6/K2.7 Kimi CoT sets were found but are **out of scope** for a K3 library and were not merged in.

## How a dataset gets in Every candidate is **downloaded and inspected** — never judged by its name: 1. **Readable** — it actually downloads and parses. 2. **Structurally valid** — rows are QA / chain-of-thought / agent traces with a real question **and** a substantive response. 3. **Right model** — content or an in-row `model` field ties it to Kimi K3; sets dominated by a rival model are rejected. 4. **Not a duplicate** — dedup by `sha256(row_json)` **and** a payload fingerprint that ignores metadata wrappers.

## Provenance & honesty Every retained row is **content-verified** as genuine Kimi K3-family data. That provenance is **source-asserted and content-verified — it cannot be cryptographically certified by Moonshot AI.** No method exists to prove a block of text came from a specific model. What is guaranteed is narrower and checkable: keyword matches are removed, every row carries a real question and response, cross-model contamination is rejected, and everything excluded is listed above with a reason. ## Schema | Column | Type | Meaning | | --- | --- | --- | | `row_hash` | string | `sha256(row_json)` — de-duplication key | | `first_source_dataset` | string | upstream dataset / original author | | `first_source_config` | string | upstream config | | `first_source_split` | string | upstream split | | `first_source_row_index` | int64 | index within the upstream source | | `seen_count` | int64 | times this canonical row was seen | | `row_json` | string | the full source row as JSON | ## Loading ```python from datasets import load_dataset ds = load_dataset("Crownelius/Kimi-K3-CoT-Library", split="train") import json row = json.loads(ds[0]["row_json"]) ``` ---
