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.
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.
Raspberry Pi 5 (Recommended)
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:
| Model | Parameters | RAM Usage | Speed | Use Case |
|---|---|---|---|---|
| Phi-3 Mini | 3.8B | ~3GB | Fast | General assistant |
| Qwen2 0.5B | 0.5B | ~500MB | Very fast | Simple tasks |
| Qwen2 1.5B | 1.5B | ~1.5GB | Fast | Balanced |
| TinyLlama 1.1B | 1.1B | ~800MB | Very fast | Chat, basic tasks |
| Gemma 2B | 2B | ~1.8GB | Fast | General purpose |
Models that work but are slower:
| Model | Parameters | RAM Usage | Speed |
|---|---|---|---|
| Llama 3.2 3B | 3B | ~3GB | Moderate |
| Mistral 7B Q4 | 7B (quantized) | ~5GB | Slow |
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
htoporfree -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
- Camera captures image → Pi Camera
- Object detection → TensorFlow Lite identifies objects
- Scene understanding → Small VLM (vision-language model) describes scene
- LLM enhancement → Phi-3 generates natural language summary
- 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.

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.

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.
For those interested in comparing local AI options beyond the Pi, check out our guides on AI PCs for laptop-based local AI, or GPUs for AI if you’re ready for more powerful desktop setups. And if you’re thinking about the privacy implications of AI, our AI privacy guide covers what you need to know about keeping your data local.
The edge AI revolution is just beginning. The Pi puts you at the forefront—affordably, practically, and with a community of millions of fellow builders to learn from.
