Edge AI Deployment: Running LLMs on Your Device

Edge AI Value

Privacy: data stays on device
Speed: no network latency
Cost: zero API fees
Offline: works without internet

What Devices Can Run

Device Runnable Models Speed
iPhone 15 Pro 3B Q4 ~15 tok/s
MacBook M3 7B Q4 ~30 tok/s
Mac Studio M2 Max 13B Q4 ~25 tok/s
NVIDIA Jetson 7B Q4 ~20 tok/s
High-end Android 3B Q4 ~10 tok/s

Framework Choices

Ollama (Simplest)

ollama run llama3.2        # 3B model
ollama run codellama:7b    # coding model

MLX (Apple Silicon)

# Apple Silicon optimized
from mlx_lm import generate

response = generate(
    model="llama-3.2-3b",
    prompt="explain what a closure is"
)

llama.cpp (Universal)

# Universal, lightweight
./llama-cli -m model-q4.gguf -p "Hello"

Real Performance

# iPhone 15 Pro test
model = "llama3.2-3b-q4"
prompt = "write a Python quicksort"

# speed: ~15 tokens/second
# quality: slightly below GPT-3.5
# battery: 5% drain in 10 minutes

What Scenarios Suit

Good for Edge AI:
  ✅ privacy-sensitive data (medical, legal)
  ✅ offline scenarios (field, airplane)
  ✅ low-frequency use (save API costs)
  ✅ simple tasks (3B model enough)

Not for Edge AI:
  ❌ complex reasoning (needs larger models)
  ❌ high-frequency calls (device heats up)
  ❌ real-time chat (latency noticeable)

Conclusion

Early 2026 Edge AI is already usable.

iPhone 15 Pro + 3B Q4 model, daily simple tasks sufficient. Mac Studio can run 13B model, most scenarios comparable to cloud API.

Privacy-first or offline scenarios—Edge AI is the best choice.
