🚀 Introduction
What is Foundry Local?
Foundry Local brings the power and trust of Azure AI Foundry to your device. It includes everything you need to run AI apps locally.
As AI adoption grows, developers are increasingly looking for ways to build intelligent applications that run efficiently on local machines. Windows AI Foundry, especially its Foundry Local feature, enables developers to create AI-powered Proof of Concepts (POCs) without relying on cloud infrastructure or Azure subscriptions. This article walks you through the step-by-step process of building a POC locally using Windows AI Foundry—and addresses common challenges along the way.
🧰 Prerequisites
Before you begin, ensure you have:
- A Windows 11 machine with sufficient CPU/GPU/NPU resources.
- Internet access (for initial setup and model downloads).
- Familiarity with command-line tools and programming (Python, C#, or JavaScript).
- Installed tools:
- Foundry CLI
- Foundry Local SDK
- ONNX Runtime (optional)
🛠️ Step-by-Step Guide
Step 1: Install Foundry CLI and SDK
Install the Foundry CLI:
winget install FoundryCLI
Install the SDK for your preferred language (e.g., Python):
pip install foundry-sdk
Step 2: Choose and Download a Model
Foundry Local supports several optimized models:
- Phi-4 Reasoning
- Mistral
- Qwen 2.5 Instruct
- DeepSeek R1
Download a model:
foundry models download phi-4
Step 3: Run Inference Locally
Run inference directly from the CLI:
foundry model run phi-4 --input "Explain quantum computing in simple terms."
Step 4: Build Your Application
Example using Python:
from foundry import FoundryModel
model = FoundryModel("phi-4")
response = model.run("What is the capital of Karnataka?")
print(response)
Step 5: Test and Iterate
Test your application with different inputs. Monitor performance and refine prompts or model selection as needed.

| Challenge | Description | Solution |
|---|---|---|
| Hardware Limitations | Some models require significant memory or GPU/NPU support. | Use lightweight models like Phi-4 or quantized ONNX versions. |
| Model Compatibility | Not all models are optimized for local inference. | Stick to models officially supported by Foundry Local or convert models to ONNX format. |
| Latency Issues | Inference may be slow on older machines. | Use smaller models or optimize with ONNX Runtime and hardware acceleration. |
| Limited Documentation | Foundry Local is relatively new, so community support is still growing. | Refer to the official Foundry blog and GitHub issues for guidance. |
| Integration Complexity | Integrating AI into existing apps can be tricky. | Use SDKs and sample code provided by Microsoft to speed up development. |
📈 Use Cases for Local POCs
- Customer Support Bots
- Offline Educational Tools
- Secure Enterprise Assistants
- Healthcare Decision Support (with local data)
To run Windows AI Foundry (Foundry Local) effectively on your Tata Communications machine, here are the minimum and recommended hardware requirements for CPU, GPU, and NPU:
✅ Minimum Requirements
These are sufficient for basic model inference (e.g., small models like Phi-3.5-mini):
- Operating System: Windows 10 (x64), Windows 11 (x64/ARM), or Windows Server 2025
- CPU: Any modern x64 processor (Intel i5/Ryzen 5 or better)
- RAM: 8 GB
- Disk Space: 3 GB free
- Acceleration (Optional): None required—CPU-only inference is supported
🌟 Recommended Requirements
For smoother performance and support for larger models:
- CPU: Intel i7/Ryzen 7 or better
- RAM: 16 GB or more
- Disk Space: 15–20 GB free (for model caching)
- GPU:
- NVIDIA: RTX 2000 series or newer
- AMD: Radeon 6000 series or newer
- NPU:
- Qualcomm Snapdragon X Elite (with 8 GB or more VRAM)
- Apple Silicon (for macOS users)
Foundry Local automatically detects your hardware and downloads the most optimized model variant (CPU, GPU, or NPU) accordingly
🧩 Conclusion
Windows AI Foundry’s local capabilities make it easier than ever to build powerful, privacy-preserving AI applications without cloud dependencies. By understanding the setup process and proactively addressing common challenges, developers can rapidly prototype and deploy intelligent solutions on Windows devices.
