🧠 Lumo-8B-Instruct Model

Overview

The Lumo-8B-Instruct model is a fine-tuned version of Meta's LLaMa 3.1 8B model designed to provide highly accurate and contextual assistance for developers working on Solana and its associated ecosystems. This model is capable of answering complex questions, generating code snippets, debugging, and explaining technical concepts using state-of-the-art instruction tuning techniques.

(Knowledge cut-off date: 29th January, 2025)

🎯 Key Features

• Optimized for Solana-specific queries across ecosystems like Raydium, Helius, Jito, and more.
• Instruction fine-tuned for developer-centric workflows.
• Lightweight parameter-efficient fine-tuning via LoRA (Low-Rank Adaptation).
• Supports multi-turn conversations with context retention.
• Outputs complete code snippets and real-world usage examples.

🛠️ Installation and Usage

1. Installation

pip install transformers datasets peft wandb

2. Load the Model

from transformers import LlamaForCausalLM, AutoTokenizer

model_name = "lumolabs-ai/Lumo-8B-Instruct"

model = LlamaForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

3. Run Inference

def complete_chat(model, tokenizer, messages, max_new_tokens=128):
    inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", return_dict=True, add_generation_prompt=True).to(model.device)
    with torch.no_grad():
        outputs = model.generate(**inputs, max_new_tokens=max_new_tokens)
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

response = complete_chat(model, tokenizer, [
    {"role": "system", "content": "You are Lumo, a helpful assistant."},
    {"role": "user", "content": "Explain how to interact with Raydium API for token swaps."}
])
print(response)
