AI on Raspberry Pi: Complete Guide to Edge AI (2026)

Run AI models on Raspberry Pi 5. Complete 2026 guide to Ollama, LLMs, computer vision, and edge AI projects. Build your own AI on $80 hardware.

Raspberry PiEdge AILocal AIDIY Projects

There’s something deeply satisfying about running AI on a $80 computer the size of a credit card. While everyone else debates which cloud API to use, you can have your own AI assistant running entirely offline, on a device that fits in your pocket.

I’ve been experimenting with AI on Raspberry Pi for a while now, and I’m genuinely impressed by what’s possible. The Pi 5, especially with 8GB of RAM, can run small language models, perform real-time computer vision, and handle voice processing—all without an internet connection.

This guide walks you through everything you need to know to get started with AI on Raspberry Pi: hardware selection, setup, running large language models, computer vision projects, and optimization tips. Whether you’re building a privacy-focused assistant, an edge AI prototype, or just learning how AI works, the Pi is a surprisingly capable platform.

Why Run AI on a Raspberry Pi?

Before diving into the how, let’s address the why. Given that cloud AI APIs exist, why bother with local hardware?

Privacy and Offline Operation

This is the big one for many people. Running AI locally means:

  • Your data never leaves your network: No uploading voice recordings, photos, or documents to third-party servers
  • Works without internet: Your AI assistant keeps working when the network goes down
  • No ongoing costs: No API fees, subscriptions, or usage charges

For home automation, personal assistants, or any privacy-sensitive application, local AI makes a lot of sense.

Learning and Understanding

There’s no better way to understand how AI works than running it yourself. When you deploy a model on a Pi:

  • You see exactly how much memory it uses
  • You understand the trade-offs between model size and capability
  • You learn about quantization, inference, and optimization firsthand

This hands-on experience demystifies AI in a way that API calls never can.

Prototyping and Edge Deployment

The Raspberry Pi is perfect for:

  • Building proof-of-concept edge AI devices
  • Prototyping before expensive hardware investments
  • Deploying AI in locations without reliable connectivity
  • Educational projects and demonstrations

Many successful edge AI products started as Pi prototypes.

It’s Just Fun

Let’s be honest: running a ChatGPT-like model on a tiny computer is cool. There’s something magical about having a conversation with AI that’s running entirely on hardware you can hold in your hand.

Raspberry Pi Hardware for AI

Not all Pi models are equal for AI workloads. The official Raspberry Pi 5 specifications show significant improvements for AI work.

The Pi 5 is a significant upgrade for AI:

  • CPU: Quad-core Arm Cortex-A76 @ 2.4GHz (2-3x faster than Pi 4)
  • RAM: 4GB or 8GB options (8GB strongly recommended for LLMs)
  • GPU: VideoCore VII (supports Vulkan 1.2)
  • PCIe: External PCIe support via FFC connector (enables AI accelerators)
  • I/O: USB 3.0, Gigabit Ethernet, improved camera/display interfaces

For AI work, always get the 8GB model. The extra RAM is essential for loading larger models. The price difference is minimal compared to the capability boost.

Essential Accessories

Beyond the Pi itself, you’ll need:

  • Power Supply: Official USB-C 27W adapter (5V, 5A). Don’t skimp here—AI workloads draw significant power
  • Cooling: Active cooling is essential. The Pi 5 runs hot under AI loads. Get a case with a built-in fan or a quality heatsink with fan
  • Storage: Fast microSD or USB SSD. NVMe via HAT is even better. Models load faster from SSDs
  • RAM: As mentioned, 8GB is the minimum for LLM work

Optional AI Accelerators

For serious AI work, consider adding dedicated AI hardware:

Raspberry Pi AI Kit (Hailo-8L):

  • 13 TOPS of AI acceleration
  • Connects via PCIe to Pi 5
  • Optimized for computer vision and neural network inference
  • ~$70 USD

Google Coral USB Accelerator:

  • Edge TPU providing 4 TOPS
  • USB 3.0 connection (works with Pi 4 and 5)
  • Excellent TensorFlow Lite support
  • ~$60 USD

Intel Neural Compute Stick 2:

  • More capable vision processor
  • USB 3.0 connection
  • Good for OpenVINO models
  • ~$70 USD

For getting started, the Pi 5 alone is sufficient. Add accelerators once you understand your workload needs. For a comparison with full AI PCs, see our AI PC guide.

Setting Up Your Pi for AI

Let’s get your Pi ready for AI projects:

Operating System

Start with the latest Raspberry Pi OS (64-bit). The 64-bit version is essential for running most modern AI frameworks.

# After first boot, update everything
sudo apt update
sudo apt full-upgrade -y
sudo reboot

Python Environment

Most AI tools use Python. Set up a clean environment:

# Install Python essentials
sudo apt install python3-pip python3-venv -y

# Create a virtual environment for AI projects
python3 -m venv ~/ai-env
source ~/ai-env/bin/activate

# Upgrade pip
pip install --upgrade pip

Essential Libraries

Install the foundations for AI development:

# NumPy and basic ML libraries
pip install numpy scipy

# For computer vision
pip install opencv-python-headless

# For deep learning
pip install tflite-runtime  # Lightweight TensorFlow for inference

Swap Space

For running LLMs, increase swap space to supplement RAM:

# Edit swap configuration
sudo nano /etc/dphys-swapfile

# Change CONF_SWAPSIZE to 4096 (4GB)
# Save and exit

# Apply changes
sudo systemctl restart dphys-swapfile

This gives you more headroom for large models, though disk-based swap is slow compared to RAM.

Running LLMs with Ollama

The easiest way to run large language models on Raspberry Pi is Ollama—a tool that makes running LLMs locally almost trivial. For more on running AI locally, see our comprehensive Ollama guide.

Installing Ollama

# One-line install
curl -fsSL https://ollama.com/install.sh | sh

# Verify installation
ollama --version

Ollama handles model downloading, quantization, and inference. You don’t need to worry about most technical details.

Choosing Models for Pi

Not every model runs well on limited hardware. Here’s what works on an 8GB Pi 5:

Recommended models:

ModelParametersRAM UsageSpeedUse Case
Phi-3 Mini3.8B~3GBFastGeneral assistant
Qwen2 0.5B0.5B~500MBVery fastSimple tasks
Qwen2 1.5B1.5B~1.5GBFastBalanced
TinyLlama 1.1B1.1B~800MBVery fastChat, basic tasks
Gemma 2B2B~1.8GBFastGeneral purpose

Models that work but are slower:

ModelParametersRAM UsageSpeed
Llama 3.2 3B3B~3GBModerate
Mistral 7B Q47B (quantized)~5GBSlow

Running Your First Model

# Download and run Phi-3 Mini
ollama run phi3

# You're now chatting with an LLM on your Pi!
# Type your messages and press Enter

The first run downloads the model (a few GB), so be patient. Subsequent runs start quickly.

Example Conversation

>>> What's the capital of France?
The capital of France is Paris. It's the largest city in France 
and serves as the country's political, economic, and cultural center.

>>> Write a haiku about Raspberry Pi
Silicon wonder
Small board, endless potential
Code flows like spring streams

Response times are 2-5 seconds for small models—not instant, but perfectly usable for personal projects.

Running Ollama as a Service

To have Ollama always available:

# The installer typically sets this up automatically
# Check status:
sudo systemctl status ollama

# If not running:
sudo systemctl enable ollama
sudo systemctl start ollama

Now you can query it from other applications on your network.

Using the API

Ollama exposes a REST API you can use from any programming language:

import requests

response = requests.post('http://localhost:11434/api/generate', json={
    'model': 'phi3',
    'prompt': 'Explain what a Raspberry Pi is in one sentence.',
    'stream': False
})

print(response.json()['response'])

This opens up possibilities for integrating local LLMs into your own applications.

Computer Vision Projects

Raspberry Pi excels at computer vision, especially with a camera module attached.

Hardware Setup

Camera options:

  • Pi Camera Module 3: 12MP, autofocus, native support, ~$25
  • Pi Camera 3 NoIR: Same but without IR filter (for night vision)
  • USB webcams: Work fine, more variety

Connect the camera and enable it:

# Should work automatically on Pi 5
# Test with:
libcamera-hello --timeout 0

Basic Object Detection

Using TensorFlow Lite with a pre-trained model:

import cv2
import numpy as np
from tflite_runtime.interpreter import Interpreter

# Load a pre-trained MobileNet SSD model
interpreter = Interpreter(model_path="detect.tflite")
interpreter.allocate_tensors()

# Get input and output details
input_details = interpreter.get_input_details()
output_details = interpreter.get_output_details()

# Start camera
cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    if not ret:
        break
    
    # Preprocess frame
    input_frame = cv2.resize(frame, (300, 300))
    input_frame = np.expand_dims(input_frame, axis=0)
    
    # Run inference
    interpreter.set_tensor(input_details[0]['index'], input_frame)
    interpreter.invoke()
    
    # Get results
    boxes = interpreter.get_tensor(output_details[0]['index'])
    classes = interpreter.get_tensor(output_details[1]['index'])
    scores = interpreter.get_tensor(output_details[2]['index'])
    
    # Draw detections (simplified)
    for i in range(len(scores[0])):
        if scores[0][i] > 0.5:
            # Draw bounding box
            # ... (box drawing code)
            pass
    
    cv2.imshow('Detection', frame)
    if cv2.waitKey(1) == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

With the Hailo-8L accelerator, you can achieve 30+ FPS real-time detection. Without it, expect 2-5 FPS on Pi 5 CPU alone.

Face Recognition

Basic face detection is straightforward:

import cv2

# Load pre-trained face detector
face_cascade = cv2.CascadeClassifier(
    cv2.data.haarcascades + 'haarcascade_frontalface_default.xml'
)

cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    
    faces = face_cascade.detectMultiScale(gray, 1.1, 4)
    
    for (x, y, w, h) in faces:
        cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 2)
    
    cv2.imshow('Faces', frame)
    if cv2.waitKey(1) == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

For more sophisticated face recognition (identifying who someone is), use the face_recognition library, though it’s more computationally demanding. The face_recognition GitHub repository has excellent documentation.

Pose Estimation

Detect human body poses using MediaPipe:

import cv2
import mediapipe as mp

mp_pose = mp.solutions.pose
pose = mp_pose.Pose()
mp_draw = mp.solutions.drawing_utils

cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    rgb = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
    
    results = pose.process(rgb)
    
    if results.pose_landmarks:
        mp_draw.draw_landmarks(
            frame, 
            results.pose_landmarks,
            mp_pose.POSE_CONNECTIONS
        )
    
    cv2.imshow('Pose', frame)
    if cv2.waitKey(1) == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

This runs at about 5-10 FPS on Pi 5—sufficient for many applications.

Practical Project Ideas

Some inspiration for what you can build:

Local Voice Assistant

Build a privacy-focused assistant that runs entirely offline:

  • Wake word detection: Use a small model like Porcupine or OpenWakeWord
  • Speech-to-text: Whisper.cpp runs on Pi with acceptable speed
  • LLM response: Ollama with Phi-3 or similar
  • Text-to-speech: eSpeak or Piper TTS

Result: “Hey Pi, what’s the weather like?” → processes locally, responds in 3-5 seconds

Smart Security Camera

Edge AI for home security:

  • Person detection: TensorFlow Lite model
  • Notification: Alert only when people (not pets) are detected
  • Local storage: Record clips to USB drive
  • No subscription: Unlike Ring or Nest, no monthly fees

Plant Monitor

AI-powered plant care:

  • Camera module watching your plants
  • Disease detection: Train or use a plant disease model
  • Growth tracking: Time-lapse with change detection
  • Watering alerts: Combine with moisture sensors

AI-Powered Doorbell

Smart doorbell without cloud:

  • Camera and speaker
  • Face recognition: Know who’s at the door
  • Local LLM: “Someone’s at the door” → can even describe them
  • Optional: Two-way audio via speaker/mic

Performance Tips

Get the most from your Pi’s AI capability:

Thermal Management

AI workloads generate heat. Keep your Pi cool:

  • Use active cooling (fan) for sustained workloads
  • Monitor temperature: vcgencmd measure_temp
  • If throttling occurs (>80°C), improve cooling

Model Optimization

Choose and configure models wisely:

  • Use quantized models: Q4 or Q5 quantization reduces memory and speeds inference
  • Match model to task: Don’t use 7B parameters for simple classification
  • Batch when possible: Process multiple inputs together

Storage Speed

Faster storage helps:

  • NVMe via HAT: Fastest option, ~400MB/s
  • USB 3.0 SSD: Good option, ~300MB/s
  • Class 10 microSD: Minimum acceptable, ~90MB/s

Model loading benefits most from fast storage.

Memory Management

With limited RAM:

  • Run one large model at a time
  • Close unused applications
  • Monitor with htop or free -h
  • Use swap for occasional overflow, but don’t rely on it

Advanced Pi AI Projects

Once you’ve mastered the basics, here are more ambitious projects to try.

Multi-Model Pipelines

Combine multiple AI models for sophisticated applications:

Example: Smart Camera with Natural Language Description

  1. Camera captures image → Pi Camera
  2. Object detection → TensorFlow Lite identifies objects
  3. Scene understanding → Small VLM (vision-language model) describes scene
  4. LLM enhancement → Phi-3 generates natural language summary
  5. Text-to-speech → Piper TTS speaks the description

This pipeline runs entirely on Pi 5 with Hailo accelerator, providing a “seeing” AI that can describe what it observes in natural language.

Voice-Controlled Home Automation

Build a complete voice assistant for home control:

Components:

  • Wake word detection (Porcupine)
  • Speech recognition (Whisper.cpp)
  • Intent parsing (small LLM or rule-based)
  • Home automation integration (Home Assistant API)
  • Response generation (optional LLM)
  • Text-to-speech (Piper)

The result: “Hey Pi, turn on the living room lights” → processes locally → lights turn on. No cloud services, no privacy concerns, works during internet outages.

Robotics Applications

The Pi is popular in robotics, and AI enhances capabilities:

Vision-guided navigation:

  • Camera input for obstacle detection
  • Path planning with computer vision
  • Object recognition for tasks
  • Real-time processing with Hailo accelerator

Gesture control:

  • Hand tracking with MediaPipe
  • Gesture recognition models
  • Robot responds to hand signals

The computational constraints of Pi actually help here—if your AI works on Pi, it’s efficient enough for battery-powered robots.

AI-Enhanced Weather Station

Combine sensors with AI for intelligent weather analysis:

Traditional sensors: Temperature, humidity, pressure, wind AI additions:

  • Camera for sky condition analysis
  • Image classification: clear, cloudy, stormy, etc.
  • Correlation learning: pattern recognition from historical data
  • Natural language reports: “Conditions suggest rain within 4 hours”

This combines the Pi’s GPIO capabilities with its AI potential.

Comparison: Pi vs. Other Edge AI Platforms

The Raspberry Pi isn’t the only option. Here’s how it compares.

NVIDIA Jetson Series

Jetson Orin Nano (lowest Orin tier):

  • Much more powerful GPU (40 TOPS)
  • ~3x the price of Pi 5 ($200 vs $80)
  • Full CUDA support

  3. Update firmware: sudo apt update && sudo apt full-upgrade
  4. Check camera cable orientation (blue side toward USB ports on Pi 5)

Hailo Accelerator Not Detected

Symptoms: hailortcli shows no devices

Solutions:

  1. Verify HAT is properly seated on GPIO pins
  2. Check lspci shows Hailo device
  3. Reinstall drivers: sudo apt install hailo-all
  4. Ensure using official Pi 5 power supply (27W required)

Audio Issues (for voice projects)

Symptoms: No microphone input, no speaker output

Solutions:

  1. Check arecord -l and aplay -l for devices
  2. Configure ALSA: alsamixer
  3. Install PulseAudio if needed
  4. Verify USB audio device is recognized

Voice AI Projects in Depth

Voice interfaces are particularly compelling on Pi. Let’s go deeper.

Speech Recognition Options

Several options exist for transcribing speech on Pi:

Whisper.cpp:

  • Port of OpenAI’s Whisper to C++
  • Runs on Pi 5 CPU
  • Tiny model works well, base model is slow
  • Best quality for the resource cost
# Install whisper.cpp
git clone https://github.com/ggerganov/whisper.cpp.git
cd whisper.cpp
make

# Download tiny model
./models/download-ggml-model.sh tiny

# Transcribe audio
./main -m models/ggml-tiny.bin -f audio.wav

Vosk:

  • Offline speech recognition
  • Multiple languages available
  • Lighter than Whisper for basic tasks
  • Good for real-time transcription

Faster-whisper:

  • Optimized Whisper implementation
  • Better performance on ARM
  • Worth trying if whisper.cpp is too slow

Text-to-Speech Options

For the output side of voice AI:

Piper:

  • Fast, high-quality neural TTS
  • Runs well on Pi 5
  • Many voices available
  • Highly recommended
# Install piper
pip install piper-tts

# Use with basic command
echo "Hello from Raspberry Pi" | piper --model en_US-amy-medium --output_file hello.wav

eSpeak:

  • Lightweight, robotic voice
  • Useful for minimal resource usage
  • Not natural sounding but functional

Coqui TTS:

  • High quality but resource intensive
  • May be slow on Pi
  • Worth trying for quality-sensitive applications

Building a Complete Voice Assistant

Here’s a more detailed architecture for a Pi voice assistant:

1. Wake Word Detection:

# Using OpenWakeWord
from openwakeword.model import Model
import pyaudio
import numpy as np

model = Model(wakeword_models=["hey_jarvis"])
audio = pyaudio.PyAudio()

# Continuously listen for wake word
stream = audio.open(format=pyaudio.paFloat32, channels=1, rate=16000, input=True)
while True:
    audio_data = np.frombuffer(stream.read(1280), dtype=np.float32)
    prediction = model.predict(audio_data)
    if prediction["hey_jarvis"] > 0.5:
        # Wake word detected - start listening
        handle_command()

2. Command Processing: After wake word, record full command, transcribe with Whisper, then:

# Simple intent processing with Ollama
import requests

def process_command(transcription):
    response = requests.post('http://localhost:11434/api/generate', json={
        'model': 'phi3',
        'prompt': f'The user said: "{transcription}". Respond helpfully and briefly.',
        'stream': False
    })
    return response.json()['response']

3. Response Generation: Use TTS to speak the response:

import subprocess

def speak(text):
    subprocess.run([
        'piper', 
        '--model', 'en_US-amy-medium',
        '--output_file', '/tmp/response.wav'
    ], input=text.encode())
    subprocess.run(['aplay', '/tmp/response.wav'])

This creates a fully functional, completely offline voice assistant.

Jetson Orin Nano~$500Much more powerfulProfessional edge AI
Old Gaming PC~$400+Full desktop AISerious local LLMs
Cloud APIs$20/monthBest qualityProduction use

The Pi makes sense when:

  • Budget is limited
  • Learning is the goal
  • Privacy matters
  • Low power consumption needed
  • Physical computing integration required

Total Cost of Ownership

Beyond initial hardware, consider:

  • Electricity: Pi draws 3-25W, negligible cost
  • Storage: Models accumulate, may need more
  • Accessories: USB hub, cables, etc.
  • Time: Learning curve is an investment

The Pi is remarkably economical for what it delivers.

Real-World Deployment Considerations

If you’re deploying Pi AI beyond experimentation:

Reliability Concerns

The Pi is a hobbyist computer, not enterprise hardware:

  • SD card wear: Consider USB SSD for production
  • No ECC RAM: Memory errors possible
  • Power sensitivity: Use quality power supply, consider UPS
  • Thermal limits: Ensure adequate cooling in enclosures

For critical applications, plan for failures and have spares ready.

Security Considerations

Deploying AI comes with security responsibilities:

  • Model security: Be aware of prompt injection risks
  • Network isolation: Don’t expose Ollama to public internet
  • Data handling: Understand what data you’re processing
  • Updates: Keep OS and tools updated

Pi AI is generally safer than cloud since data stays local, but still requires attention.

Scaling Limitations

A single Pi can only do so much:

  • One user at a time: Not for multi-user scenarios
  • One model loaded: Can’t simultaneously run many models
  • Limited throughput: Not for high-volume processing

For anything beyond personal/prototype use, plan for proper infrastructure.

When to Graduate from Pi

Signs it’s time for more powerful hardware:

  • Response times frustrate users
  • Need to run larger models
  • Processing multiple inputs simultaneously
  • Production reliability requirements
  • Edge AI at scale (multiple cameras, sensors)

The Pi gets you started; recognize when you’ve outgrown it.

Frequently Asked Questions

Can I run ChatGPT on a Raspberry Pi?

Not ChatGPT specifically (it’s OpenAI’s cloud service), but you can run similar open-source LLMs locally. Models like Phi-3, TinyLlama, and Qwen2 provide conversational AI comparable to early GPT models. They’re not as capable as GPT-5, but surprisingly useful.

Which Raspberry Pi model should I buy for AI?

Raspberry Pi 5 with 8GB RAM is the only serious choice for LLM work. The 4GB model can run very small models but limits your options. Pi 4 works for computer vision but struggles with LLMs. Older Pis are generally too slow for meaningful AI.

How fast is local AI compared to cloud APIs?

Slower, but not unusably so. Expect 2-5 seconds per response for small LLMs on Pi 5, versus sub-second from cloud APIs. Computer vision can hit real-time (30 FPS) with accelerators. For many personal projects, the speed is acceptable.

Do I need the AI Kit accelerator?

For LLMs, no. Ollama runs on CPU and doesn’t benefit from the Hailo accelerator. For computer vision, maybe. If you need real-time video processing (30 FPS), the accelerator helps significantly. For basic detection at a few FPS, CPU works fine.

Can I fine-tune models on Raspberry Pi?

Not practically. Training and fine-tuning require much more compute than inference. Fine-tune on a desktop or cloud GPU, then deploy the resulting model to your Pi for inference.

Conclusion

Running AI on Raspberry Pi is more practical than ever in 2026. The Pi 5’s improved performance, combined with tools like Ollama and efficient small models, makes local AI accessible for hobbyists, educators, and developers alike.

The sweet spot is an 8GB Pi 5 running quantized 1-3B parameter models. This setup handles conversational AI, basic vision tasks, and voice processing—all offline and private. Add an AI accelerator if you need real-time video processing.

The Pi won’t replace cloud AI for heavy workloads, but it’s not trying to. It excels at:

  • Privacy-focused personal assistants
  • Edge AI prototyping
  • Educational exploration
  • Offline operation
  • Cost-effective deployment

If you’ve been curious about edge AI but haven’t tried building anything, the Raspberry Pi is the perfect starting point. The total cost is under $150 for a complete AI-capable system, and the learning experience is invaluable.

What will you build? Start with Ollama and a simple chat model, then expand from there. The Pi community has extensive resources, and new AI tools are constantly improving support for ARM-based hardware.

The journey from “Hello World” to a functional AI project is shorter than you might think. The Pi lowers barriers to entry while teaching fundamentals that apply to any AI deployment. Whether you’re building a privacy-focused assistant, learning about how language models work, or prototyping an edge AI product, the Raspberry Pi provides an accessible entry point.
