Libraries

How to use grimjim/Llama-Nephilim-Metamorphosis-v2-8B with Transformers:

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

pipe = pipeline("text-generation", model="grimjim/Llama-Nephilim-Metamorphosis-v2-8B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("grimjim/Llama-Nephilim-Metamorphosis-v2-8B")
model = AutoModelForCausalLM.from_pretrained("grimjim/Llama-Nephilim-Metamorphosis-v2-8B")
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]:]))

Llama-Nephilim-Metamorphosis-v2-8B

This repo contains a merge of pre-trained language models created using mergekit.

A coherent Llama 3 model (composed of fine-tunes based on Instruct) was merged at low weight into a Llama 3.1 Instruct model. No fine-tuning was performed afterward. The resulting model is mostly coherent for direct chat and text generation, retaining long context capability of 3.1. A gradient merge was used at the ends and the the embed_tokens and lm_head layers retained from 3.1, which should better preserve handling of context above 8K tokens.

Testing has been performed out to 16K context, using temperature 1 and minP 0.01. Safety remains mostly intact.

Built with Llama.
