Instructions to use SatorTenet/StoryEngine-2B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use SatorTenet/StoryEngine-2B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="SatorTenet/StoryEngine-2B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("SatorTenet/StoryEngine-2B")
model = AutoModelForCausalLM.from_pretrained("SatorTenet/StoryEngine-2B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

StoryEngine-2B

StoryEngine-2B is a fine-tuned version of Qwen/Qwen3.5-2B for interactive fiction and guided story experiences.

The model guides users through immersive narrative experiences, presenting vivid scenes and meaningful choices at each step.

Model Details

Base model: Qwen/Qwen3.5-2B
Fine-tuning method: QLoRA (r=16, alpha=32)
Training data: 3,140 interactive fiction examples across multiple genres
Training hardware: NVIDIA GeForce GTX 1060 6GB
Training time: ~9.5 hours

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "SatorTenet/StoryEngine-2B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, dtype=torch.float16, device_map="auto")

messages = [
    {
        "role": "system",
        "content": (
            "You are StoryEngine — an interactive fiction model.\n"
            "Genre: Dark Fantasy | Tone: tense, mysterious\n"
            "Scene: 1/5\nVitality: 100 | Saga: 0"
        ),
    },
    {"role": "user", "content": "Start a new story."},
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=300, temperature=0.8, top_p=0.9, do_sample=True)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
