+
+> **Discord-Dialogues-Preprocessed-Luna-Protocol** is a preprocessed fork of [mookiezi/Discord-Dialogues](https://huggingface.co/datasets/mookiezi/Discord-Dialogues), adapted for fine-tuning Qwen2.5-family models as part of the **Luna Protocol** project.
+
+This dataset contains anonymized Discord conversations for training and evaluating realistic conversational AI models in a ChatML-friendly format. It is derived directly from `mookiezi/Discord-Dialogues` with two targeted preprocessing steps applied (see below) — the underlying conversations, filtering pipeline (PII removal, ToS-risk filtering, dedup), and licensing are unchanged from the original.
+
+## What was changed from the original dataset
+
+The original `mookiezi/Discord-Dialogues` ships each example as a ChatML string terminated with the literal token `<|end_of_text|>`. That token is **not** a recognized special token in the Qwen2.5 tokenizer (it originates from Llama 3 / GPT-oss style tokenizers), which meant it would get split into several ordinary sub-tokens during fine-tuning instead of being treated as a single end-of-sequence marker — actively harmful for teaching a model where to stop generating.
+
+Two preprocessing steps were applied on top of the original `text` column:
+
+1. **EOS token fix** — every occurrence of `<|end_of_text|>` was replaced with the actual EOS token of the target tokenizer (`<|im_end|>` for Qwen2.5). Any example that didn't already end with an EOS marker had one appended.
+2. **Length filtering** — examples were filtered using the dataset's own `tokens` column, keeping only exchanges with **8 to 512 tokens**. This removes degenerate very-short exchanges and caps sequence length for training efficiency. Only 127 out of 7,300,966 examples fell outside this range and were dropped.
+
+No other changes were made: no re-cleaning, no re-deduplication, no additional filtering of content. The `tokens`, `turns`, `characters`, and `words` metadata columns from the original dataset are preserved as-is (note: `tokens` reflects the original tokenizer's count, not a recount after the EOS substitution).
+
+## Columns
+
+| Column       | Type   | Description                                                                 |
+| ------------ | ------ | ----------------------------------------------------------------------------- |
+| `text`       | string | ChatML-formatted conversation, EOS-corrected for Qwen2.5 (`<|im_start|>`/`<|im_end|>`) |
+| `tokens`     | int64  | Token count from the original dataset (used for the 8–512 filter)             |
+| `turns`      | int64  | Number of conversational turns                                                |
+| `characters` | int64  | Character count                                                               |
+| `words`      | int64  | Word count                                                                    |
+
+## Intended use
+
+Fine-tuning small-to-mid-size causal language models (tested with Qwen2.5-1.5B-Instruct via QLoRA/Unsloth) to emulate informal, human Discord conversation style, as part of the **Luna Protocol** model family (e.g. `Luna-Protocol-1.5B-Discord-Dialogues`).
+
+If you're targeting a different base model whose EOS token differs from Qwen2.5's `<|im_end|>`, you'll want to re-run the EOS substitution step against the original dataset rather than reusing this fork as-is.
