# tiny_schiller

A small (~2 MB) German-language analogue to Karpathy's [tiny_shakespeare](https://huggingface.co/datasets/karpathy/tiny_shakespeare) — 11 of Friedrich Schiller's dramatic works, cleaned and tokenised for tutorial-scale language models.

For a compact, agent-friendly summary (file inventory, load patterns, licensing), see [DATA_CARD.md](DATA_CARD.md).

*"Das Leben ist nur ein Moment, der Tod ist auch nur einer."* — Friedrich Schiller

## Corpus

~2.07 MB · 11 works · 2,019,857 characters · sourced from DraCor / GerDraCor (CC0). See [LICENSING.md](LICENSING.md) for details.

| Tokenizer | Tokens | chars/token |
|---|---|---|
| character-level | 2,019,857 | 1.00 |
| GPT-2 BPE | 854,611 | 2.36 |
| `cl100k_base` | 642,593 | 3.14 |

Use **character-level** for teaching-scale models (88-token vocab, no tokenizer needed). Use **cl100k** over GPT-2 when sequence length matters — German umlauts and compounds tokenise 25% more efficiently.

## Works

- Die Räuber
- Die Verschwörung des Fiesco zu Genua
- Kabale und Liebe
- Don Carlos, Infant von Spanien
- Wallensteins Lager
- Maria Stuart
- Die Jungfrau von Orleans
- Die Braut von Messina oder Die feindlichen Brüder
- Wilhelm Tell
- Die Piccolomini
- Wallensteins Tod

## Quick Start — nanoGPT

```bash
python schiller_char/prepare.py    # char-level, 88-vocab
python schiller_bpe/prepare.py     # GPT-2 BPE, 50k vocab
python schiller_cl100k/prepare.py  # cl100k, 100k vocab
```

## HuggingFace Datasets

```python
from datasets import load_dataset

ds = load_dataset("mrkschtr/tiny_schiller")
print(ds["train"][0]["title"])
print(ds["train"][0]["text"][:200])
```

9 works in train, 2 in test (Wilhelm Tell, Die Braut von Messina). Each row is one complete work with `title` and `text` fields.

## Instruction & Character Datasets

Pre-built instruction-format parquet files are in `data/` on the Hub.

**General dialogue style** — 7,607 examples teaching Schiller's dramatic register:
```python
ds = load_dataset("mrkschtr/tiny_schiller", data_files="data/instruct.parquet", split="train")
print(ds[0]["prompt"])
print(ds[0]["completion"])
```

**Per-character** — fine-tune a model to respond as a specific character:
```python
# 330 examples as Wallenstein · 325 as Carlos · 313 as Fiesco
# 237 as Marquis · 195 as Ferdinand · 194 as Königin · ...
ds = load_dataset("mrkschtr/tiny_schiller", data_files="data/char_WALLENSTEIN.parquet", split="train")
```

Rebuild locally (generates `data/instruct.parquet` + 89 `data/char_*.parquet` files by default):
```bash
python scripts/build_instruct.py               # all characters
python scripts/build_instruct.py --list-characters   # show available characters + turn counts
python scripts/build_instruct.py --character KARL    # single character only
```

## Fine-tuning small LLMs

```bash
pip install transformers trl datasets accelerate
python examples/finetune_sft.py --model TinyLlama/TinyLlama-1.1B-Chat-v1.0
```

Default context window is 2048 tokens. Match your model with `--context_length`:

```bash
python examples/finetune_sft.py --model microsoft/Phi-3-mini-4k-instruct --context_length 4096
python examples/finetune_sft.py --model Qwen/Qwen2.5-0.5B --context_length 4096
```

Tested: TinyLlama 1.1B · Phi-3 Mini 3.8B · Llama 3.2 1B/3B · Qwen2.5 0.5B–3B.
