Instructions to use AdminReal/NexusCoder with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use AdminReal/NexusCoder with Transformers:

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

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

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("AdminReal/NexusCoder")
model = AutoModelForCausalLM.from_pretrained("AdminReal/NexusCoder", 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)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

🧠 Nexus Coder

AI Code & Security Engine — Qwen2.5-Coder based

A deployable coding model: Qwen2.5-Coder-1.5B weights + Nexus Coder agent engine (skills & tools)

📖 Introduction

Nexus Coder is a working AI model combining:

Model weights: Qwen2.5-Coder-1.5B-Instruct (Apache 2.0) — a strong 1.5B coding model.
Agent engine: the Nexus Coder framework (nexus/) — 60+ skills and 80+ tools with automatic registration, agent planner/router/memory/safety, data pipeline, and training utilities.

🚀 Quick Usage

The model is a standard Qwen2ForCausalLM. Load it with transformers:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "AdminReal/NexusCoder"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

messages = [{"role": "system", "content": "You are Nexus Coder, a helpful coding assistant."},
            {"role": "user", "content": "Write a Python function to compute fibonacci."}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt")
out = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
