Lumen 7B v2

<div align="center">

Lumen is an agentic AI coding assistant built by Alexander Wondwossen (TheAlxLabs). Fine-tuned on Qwen2.5-Coder-7B-Instruct with LoRA for tool-use, git, GitHub, and Conductor integration.

What is Lumen?

Lumen is a locally-running agentic coding AI designed to work inside Conductor. It can:

• —Write, read, and edit code and files
• —Run shell commands and verify results
• —Use git and GitHub (commits, branches, PRs, Actions, secrets)
• —Debug TypeScript, Python, Node.js, and Bash
• —Call Conductor plugins as tools
• —Control your development environment autonomously

Model Details

Quickstart with Ollama

ollama pull thealxlabs/lumen
ollama run thealxlabs/lumen "What are you?"

Quickstart with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

base = "Qwen/Qwen2.5-Coder-7B-Instruct"
adapter = "alxstuff/Lumen-7b-v2"

model = AutoModelForCausalLM.from_pretrained(base, torch_dtype=torch.float16)
model = PeftModel.from_pretrained(model, adapter)
tokenizer = AutoTokenizer.from_pretrained(base)

messages = [
    {"role": "system", "content": "You are Lumen, an agentic AI coding assistant built by Alexander (TheAlxLabs)."},
    {"role": "user", "content": "Create a Python script that fetches weather data."}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

System Prompt

You are Lumen, an agentic AI coding assistant built by Alexander (TheAlxLabs). 
You run inside Conductor. You have tools: run_shell, read_file, write_file, conductor_plugin. 
Think step-by-step. Use tools to verify.

Tools Lumen Knows

Training Data

Lumen was trained on curated agentic multi-turn conversations covering:

• —Git workflows (commit, branch, push, reset, rebase, cherry-pick)
• —GitHub (PRs, issues, Actions CI, secrets)
• —TypeScript / Node.js debugging
• —Python virtual environments and debugging
• —Bash scripting and disk management
• —Conductor plugin installation and debugging
• —Port conflicts and environment variable issues
• —Lumen self-knowledge (identity, capabilities)
