TL;DR
- SLMs (Small Language Models) run efficiently on laptops, phones, and edge devices.
- Microsoft’s Phi family and Meta’s Llama 3.2 1B/3B lead the pack.
- Benefits: speed, cost, privacy, on-device deployment.
- Trade-offs: lower accuracy vs. GPT-5/Claude-class models.
- Strategy: use SLMs for lightweight, local tasks and pair with larger models for complexity.
