# A College Student Built ATLAS to Beat Frontier Coding Models Locally

> ATLAS is a fully local, open-source coding agent that wraps a frozen 14B model in a multi-phase pipeline to hit 74.6% on LiveCodeBench — no API keys, no cloud, no fine-tuning required.

[ATLAS](https://github.com/itigges22/ATLAS) (Adaptive Test-time Learning and Autonomous Specialization) is a self-hosted coding agent built by a single college student on a single consumer GPU. The premise is simple but powerful: instead of relying on a bigger model or expensive API calls, ATLAS wraps a compact, frozen 14B model in a smart pipeline that plans, generates multiple candidates, scores them, tests them in a sandbox, and repairs failures , all locally, with no data leaving your machine.

ATLAS achieves 74.6% on LiveCodeBench using a frozen 14B quantized model (Qwen3-14B-Q4\_K\_M) on a single consumer GPU (RTX 5060 Ti 16GB). That's a result that puts it in the same conversation as hosted frontier models , and it costs nothing but electricity per query.

## The Problem It Solves

The standard coding agent workflow is a single-shot gamble: you send a prompt, you get one generation, and you hope it works. When the model is small, that gamble fails often. ATLAS is a local coding agent that brings frontier-style reasoning and verification to compact open models, putting more intelligence in the system around the model , planning, candidate generation, quality scoring, sandboxed testing, and repair , so smaller models can tackle real software work entirely on your own hardware, without a hosted API or per-token fees.

This matters most if you care about privacy, cost control, or just don't want to depend on a third-party service that can change its terms, rate-limit you, or disappear. ATLAS does not intentionally upload your repository or prompts to a hosted model or ATLAS-operated service.

## How the Pipeline Actually Works

The magic is in the orchestration layer, not the model. ATLAS runs a multi-phase process called the V3 Pipeline every time you make a request:

1. **PlanSearch:** Before writing any code, ATLAS generates a structured, constraint-driven plan. It figures out what the problem requires before attempting a solution.
2. **DivSampling:** Multiple candidate solutions are generated with varied temperatures and strategies , not just one attempt, but a diverse pool.
3. **Budget Forcing:** Thinking-token budgets are allocated per phase, so harder problems get more reasoning compute.
