RubiNet

RubiNet is a bilingual English-Turkish conversational model release built on top of mistralai/Ministral-3-3B-Base-2512. This release is provided as a LoRA adapter and reflects the RubiNet chat tuning setup used in the local HMC-based deployment stack.

The goal of RubiNet is to provide sharper dialogue quality, stronger consistency, and better reasoning behavior than the untuned base model in local assistant usage. In the local serving stack, RubiNet can also be paired with math-oriented prompting and calculator verification for safer arithmetic handling.

This repository does not bundle the original base model weights. You need access to the base model mistralai/Ministral-3-3B-Base-2512 in order to load this adapter.

Loading Example

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base_model_id = "mistralai/Ministral-3-3B-Base-2512"
adapter_id = "DevHunterAI/RubiNet"

tokenizer = AutoTokenizer.from_pretrained(base_model_id)
base_model = AutoModelForCausalLM.from_pretrained(base_model_id, device_map="auto")
model = PeftModel.from_pretrained(base_model, adapter_id)

messages = [
    {"role": "user", "content": "Explain why 2+2=4 in a short way."}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
output = model.generate(**inputs, max_new_tokens=128, temperature=0.0)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Training / Adaptation Note

RubiNet is a fine-tuned conversational adaptation derived from mistralai/Ministral-3-3B-Base-2512. The release uses an HMC-oriented chat setup and is intended for local assistant-style interaction, bilingual usage, and reasoning-focused experimentation.

Limitations

• This release is an adapter, not a full standalone base checkpoint.
• Benchmark scores depend on the exact prompting and inference configuration.
• Arithmetic reliability improves when RubiNet is combined with external calculator verification in the serving layer.
• GSM8K performance is still limited relative to stronger specialized math-tuned models.
