🕵️ Agatha Christie Style LoRA — Gemma-2-2B-IT
This model is a LoRA fine-tuned version of Google’s Gemma-2-2B-IT, trained to generate prose in the classic style of Agatha Christie.
It captures the tone, pacing, domestic atmosphere, and subtle psychological tension characteristic of Christie’s detective fiction.
The model is intended for story continuation, creative writing, and mystery scene generation.
It is a causal LM, not an instruction-tuned chat model.
✨ Model Details
- Model type: Causal language model (LoRA adapter)
- Base model:
google/gemma-2-2b-it - Fine-tuning method: LoRA (PEFT)
- Training framework: Hugging Face AutoTrain
- Languages: English
- Primary domain: Fiction, mystery, detective prose
- Task: Text generation (story continuation)
🎯 Intended Use
This model is suitable for:
- Generating text in the Agatha Christie style
- Continuing mystery scenes
- Creative writing assistance
- Prototyping detective stories
- Experimenting with stylistic transfer
Not recommended for:
- Real-world Q&A
- Safety-critical applications
- Factual reasoning
- Chat-assistant behavior without custom prompting
📚 Training Data
The model was trained on:
realdanielbyrne/AgathaChristieText
A plain-text dataset containing ~13,000 rows of Agatha Christie prose.
No instruction template was used; the model was trained purely on unstructured text to learn style rather than task formats.
🔧 Training Configuration
- Epochs: 3
- Block size: 1024
- Learning rate: 3e-5
- Batch size: AutoTrain default
- Optimizer: AdamW
- Chat template: None (causal LM)
- LoRA target modules: Linear projection layers of Gemma
Training was performed using AutoTrain, which handled preprocessing, batching, and evaluation.
🧠 Model Behavior
The model tends to produce:
- restrained, elegant British prose
- domestic settings and quiet tension
- subtle descriptions of character behavior
- slow, methodical narrative pacing
- attention to objects, rooms, and small clues
Example characteristics:
- No supernatural or horror tone unless explicitly prompted
- Minimal modern slang
- High coherence for 1–3 paragraphs of continuation
- Strong stylistic adherence to Christie’s sentence rhythm
⚠️ Limitations and Biases
- May repeat narrative structures due to small dataset size
- Not optimized for long-range story consistency
- Inherits biases present in Agatha Christie’s historical works
- Not suited for factual or logical reasoning
- Can generate outdated cultural norms reflective of 20th-century British literature
📊 Evaluation
This model was not evaluated using standard NLP benchmarks, as its purpose is stylistic generation rather than accuracy on downstream tasks.
Qualitative evaluation shows:
- Strong stylistic similarity to Christie’s prose
- High coherence in short continuations
- Appropriate tone, atmosphere, and pacing
