Aurora Code 1

Aurora-Code-1

Northern Lights for your codebase.

Aurora-Code-1 is a 35B Mixture-of-Experts coding model (3B parameters activated per token) built by Perciqa, a Canadian AI company. Fine-tuned from Qwen3.6-35B-A3B on 2,700 high-quality agentic coding instruction pairs, Aurora-Code-1 is optimised for code generation, debugging, code review, and multi-step agentic coding workflows.

What Aurora-Code-1 does

Aurora-Code-1 is tuned specifically for developers who need a model they can deploy, audit, and fully control — on their own infrastructure.

• Code generation — write functions, classes, and complete programs across 40+ languages
• Debugging — identify root causes and produce clear, actionable fixes
• Code review — flag security issues, suggest refactors, explain tradeoffs
• Agentic tasks — multi-step tool use, planning, and repository-level reasoning

No black boxes. No data leaving your infrastructure. Your model, your terms.

Quickstart

Install

pip install "transformers>=4.51.0" accelerate

Hardware: ~60–65 GB VRAM. A single 80 GB A100/H100 or two 48 GB GPUs work well. device_map="auto" supports CPU offload for smaller setups.

Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Perciqa/Aurora-Code-1"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto",
)

system_prompt = (
    "You are Aurora, an AI code assistant built by Perciqa. "
    "You help developers write, review, and understand code. "
    "You provide clear, correct, and complete solutions. "
    "When you're unsure, you say so."
)

messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": "Write a Python function to merge two sorted lists."},
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=2048,
    temperature=0.7,
    do_sample=True,
)
response = tokenizer.decode(outputs[0][len(inputs.input_ids[0]):], skip_special_tokens=True)
print(response)

vLLM (recommended for production)

pip install vllm
vllm serve Perciqa/Aurora-Code-1 --max-model-len 32768

Query via the OpenAI-compatible API:

from openai import OpenAI

client = OpenAI(base_url="http://localhost:8000/v1", api_key="token-abc123")

response = client.chat.completions.create(
    model="Perciqa/Aurora-Code-1",
    messages=[
        {"role": "system", "content": "You are Aurora, an AI code assistant built by Perciqa."},
        {"role": "user", "content": "Refactor this function to be more Pythonic."},
    ],
    max_tokens=2048,
)
print(response.choices[0].message.content)

Argus Integration

Argus is Perciqa's open-source agent observability SDK — trajectory tracing, token usage, eval-in-production. Aurora-Code-1 integrates natively.

import argus
from openai import OpenAI

argus.init(server_url="http://localhost:8000", agent_name="aurora-coder")
client = OpenAI(base_url="http://localhost:8000/v1", api_key="token-abc123")

@argus.trace(kind="agent")
def aurora_code(query: str) -> str:
    response = client.chat.completions.create(
        model="Perciqa/Aurora-Code-1",
        messages=[
            {"role": "system", "content": "You are Aurora, an AI code assistant built by Perciqa."},
            {"role": "user", "content": query},
        ],
    )
    return response.choices[0].message.content

result = aurora_code("Write a TypeScript function that validates an email address.")
print(result)

Argus captures latency, token usage, inputs/outputs, and agent spans — visible in the Argus dashboard with no extra instrumentation.

Performance

Benchmarks in progress. Independent evaluations on LiveCodeBench, SWE-bench Verified, HumanEval+, and MBPP+ will be published here before the stable release.

Training

Aurora-Code-1 v1 is trained with LoRA supervised fine-tuning on a curated set of 2,700 agentic coding instruction pairs covering:

• Code generation (Python, TypeScript, Go, Rust, and more)
• Debugging and root cause analysis
• Code review and refactoring
• Multi-step agentic reasoning and tool use

Future versions will expand the dataset and move to full fine-tuning.
