Libraries

How to use GenueAI/Geode-Onyx-2 with Transformers:

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

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

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("GenueAI/Geode-Onyx-2")
model = AutoModelForCausalLM.from_pretrained("GenueAI/Geode-Onyx-2")
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]:]))

	# 💎 Geode Onyx 2 (3B)

	Onyx 2 is a 3-billion parameter conversational AI model, fine-tuned as part of the second generation of the Geode model family.

	## Model Details

	- Base Model: Qwen 2.5 3B Instruct
	- Parameters: 3 Billion
	- Fine-Tuning: LoRA (r=32, alpha=64)
	- Training Loss: 0.40
	- Precision: FP16
	- License: Apache 2.0

	## The Geode Family (Second Generation)

	The Geode family is Genue AI's lineup of locally-runnable conversational models. In the second generation, Beryl has been retired and replaced by Pyrite, a specialized coding model:

	\| Model \| Parameters \| Role \|
	\|-------\|------------\|------\|
	\| Pyrite \| 7B \| Coding specialist \|
	\| Onyx \| 3B \| Balanced logic & personality \|
	\| Thaumite \| 8B \| Flagship, highest capability \|

	Note: Beryl (0.5B) was the original lightweight experimental model in the first generation and has been replaced by Pyrite, which focuses specifically on code generation tasks.

	## Usage

	Onyx 2 uses the Qwen Instruct prompt format:

	```python
	from transformers import AutoModelForCausalLM, AutoTokenizer
	import torch

	model = AutoModelForCausalLM.from_pretrained(
	"GenueAI/Geode-Onyx-2",
	torch_dtype=torch.float16,
	device_map="auto",
	trust_remote_code=True
	)
	tokenizer = AutoTokenizer.from_pretrained("GenueAI/Geode-Onyx-2")

	prompt = "<\|im_start\|>user\nWhat is your name?<\|im_end\|>\n<\|im_start\|>assistant\n"
	inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
	outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)
	print(tokenizer.decode(outputs[0], skip_special_tokens=True))
	```

	## Training Data

	Fine-tuned on a curated dataset of 1,013 examples covering:

	- Identity & self-awareness - AI assistant identity and capabilities
	- Mathematical reasoning - Arithmetic, algebra, word problems
	- General knowledge - Broad factual knowledge

	- Physics problems - Falling objects, thermodynamics
	- Genue AI ecosystem knowledge - Company information, model family details
	- Conversational generalization - Natural dialogue patterns
	- Anti-hallucination training - Proper handling of unknown information (time, location, preferences)

	## Model Architecture

	- Base: Qwen 2.5 3B Instruct
	- Adapter: LoRA with r=32, alpha=64
	- Target modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
	- Trainable parameters: 59.9M (1.9% of total)

	## Training Details

	- Training regime: FP16 mixed precision
	- Epochs: 2
	- Batch size: 8
	- Learning rate: 2e-4
	- Training time: ~8 minutes on RTX 3090
