Libraries

How to use Vortex5/Harmonic-Lumina-12B with Transformers:

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

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

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

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

💠 Harmonic-Lumina-12B 💠

01 // Overview

Harmonic-Lumina-12B is a model merged using a custom harmony_prism method — It merges Harmony-Bird-12B, Violet-Mist-12B, and Luminous-Shadow-12B.

02 // Custom Merge Method

A merge algorithm that aligns models across structural (spatial) and energetic (style/variance) domains. It performs stochastic coherence sampling—random block analysis of parameter deltas—to measure local structure and energy similarity. Using these signals, it adaptively adjusts per-model weights through entropy-stabilized softmax and a decaying EMA center, achieving smooth, artifact-free convergence that preserves each model’s “resonance” while unifying tone and logic.

focus — Controls decisiveness of weighting; higher = stronger emphasis on the most coherent contributors. (Global or per-model.).
blend — Balances between spatial structure (0) and energy signature (1), determining whether the merge favors logic/shape or expressive style. (Global or per-model.)
max_goodness — Convergence threshold for coherence optimization; the process stops when this target is reached.
refinement_steps — Number of refinement passes; higher values yield smoother and more unified results at the cost of time.
