Libraries

How to use Vortex5/Amber-Starlight-12B with Transformers:

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

pipe = pipeline("text-generation", model="Vortex5/Amber-Starlight-12B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Vortex5/Amber-Starlight-12B")
model = AutoModelForCausalLM.from_pretrained("Vortex5/Amber-Starlight-12B")
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]:]))

Prose

I tested the model with an LLM using neutral prompts to summarize its narrative style.

Amber-Starlight writes in a warm, readable, and emotionally sincere style. Scenes tend to unfold with gentle pacing, clear visuals, and a focus on small-scale relationships rather than spectacle or heavy genre tropes. It reads like a cozy realist storyteller—soft-spoken, human-focused, and grounded in everyday detail. The model handles sentiment and character interactions cleanly without sliding into purple prose or over-complex structure. While not experimental or edgy, it excels at approachable, heartfelt narrative that feels lived-in and sincere.
