Libraries

How to use Naphula/Riemannian-Redshift-12B-v1 with Transformers:

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

pipe = pipeline("text-generation", model="Naphula/Riemannian-Redshift-12B-v1")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Naphula/Riemannian-Redshift-12B-v1")
model = AutoModelForCausalLM.from_pretrained("Naphula/Riemannian-Redshift-12B-v1", device_map="auto")
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)

# 🌌 Riemannian Redshift 12B v1

This is a merge of pre-trained language models created using [mergekit](https://github.com/cg123/mergekit).

## Merge Details
### Merge Method

This is an experimental `karcher` merge of several high quality [Vortex5](https://huggingface.co/Vortex5) models. I used `float32` precision and `max_iter: 1000` to ensure the best bits were chosen for the Riemannian center. This merge took 5 hours using [graph_v18](https://huggingface.co/spaces/Naphula/model_tools/blob/main/graph_v18.py) as an accelerant with 8GB VRAM.

This model was merged using the [Karcher Mean](https://en.wikipedia.org/wiki/Karcher_mean) merge method.

### Models Merged

The following models were included in the merge:
* [Vortex5/Maroon-Sunset-12B](https://huggingface.co/Vortex5/Maroon-Sunset-12B)
* [Vortex5/Azure-Starlight-12B](https://huggingface.co/Vortex5/Azure-Starlight-12B)
* [Vortex5/Scarlet-Seraph-12B](https://huggingface.co/Vortex5/Scarlet-Seraph-12B)
* [Vortex5/Amber-Starlight-12B](https://huggingface.co/Vortex5/Amber-Starlight-12B)
