The premise
Small AI models like Phi and Gemma run on phones and laptops with strong privacy properties — but capability gaps versus cloud flagships remain large.
What AI does well here
- Privacy-preserving local inference
- Predictable latency without network
- Zero cost per inference after deployment
- Solid performance on narrow tasks like summarization
What AI cannot do
- Match flagship reasoning quality
- Handle long contexts without significant memory cost
