Small Language Models (SLMs): Why On-Device AI Is Having a Moment
Nanostack1 min read
Phi, Gemma, and Llama 3 variants are proving that smaller models can match larger ones on narrow tasks — with privacy, cost, and latency wins.
Bigger isn't always better — SLMs are closing the gap
In 2026, teams are shipping 3B–8B parameter models that outperform 70B+ models on focused tasks like classification, extraction, and structured output. The secret: task-specific fine-tuning, distillation, and tight eval loops.
Where SLMs win today
- Privacy-first apps: Medical triage, legal doc review, and HR workflows that can't send data to cloud APIs.
- Real-time UX: Sub-200ms inference on laptops and phones without network round-trips.
- Cost at scale: Zero per-token API fees when you own the inference stack.
How to pick and deploy
Start with your eval set, not a leaderboard. Benchmark 2–3 SLMs on your actual inputs, quantize to INT4/INT8, and measure accuracy vs latency trade-offs. Nanostack helps teams ship SLM pipelines with ONNX Runtime and CoreML — see our AI development services.
