+# roleplay-slm-mix
+
+A curated multi-source conversation corpus for training small (sub-1B) language
+models to do persona-consistent roleplay chat. All conversations are normalized to
+a strict `User:` / `Assistant:` turn format with an optional persona/scene header.
+
+Built for the TinyRole program (byte-level tiny SLMs).

+**`character-llm-chat.txt` is NON-COMMERCIAL (CC-BY-NC-4.0).** It is a separate
+file so the MIT-licensed files stay permissive. Do not use it commercially.
+
+**Coming in v2:** RoleBench train split (Apache-2.0, ~85 MB — eval test split stays
+out), PIPPA-filtered (Apache-2.0, pending NSFW filter pass).
+
+**Deliberately excluded (unlicensed — cannot redistribute):** WorryFree scenarios,
+hieunguyenminh/roleplay, AlekseyKorshuk synthetic trio. Used in training but not
+redistributable.
+
+## Format
+
+Each conversation is a text block, blocks separated by a blank line:
+
+```
+[optional persona/scene header line]
+User: <first user turn>
+Assistant: <first assistant turn>
+User: ...
+Assistant: ...
+```
+
+Persona headers (when present) are a single capitalized line describing the
+character/scene, NOT prefixed with a role.
+
+## Per-source cleaning
+
+- **coser-clean**: 771 classic-book characters. Strict User/Assistant alternation
+  (merged consecutive same-role turns), name-prefix and stage-direction/asterisk
+  stripping, dropped < 4-turn conversations. 305k raw → 76,004 clean.
+- **mmrole-chat**: 85 characters, text-only extraction from the multimodal dataset
+  (image references dropped; scene-description user turns retained). MIT.
+- **character-llm-chat**: 9 historical/literary figures (Beethoven, Cleopatra,
+  Caesar, Hermione, Newton, Socrates, Spartacus, Voldemort, MLK) via Experience
+  Reconstruction (EMNLP 2023). Character role → Assistant, interlocutor → User.
+  CC-BY-NC-4.0.
+
+## Intended use
+
+Fine-tuning small chat/roleplay models, as the final chat/persona stage of a
+curriculum (grounding → narrative → this mix).
