Summary
KDnuggets says small language models work best when tasks bring their own information, identifying three practical use cases: private document structuring, high-volume bulk labeling, and low-latency on-screen assistance.
Three limits still define SLM performance: extended multi-step reasoning, frozen and weaker recall, and effective context that can break well before the advertised window—sometimes around 40%, with “lost in the middle” errors.
For sensitive data that cannot leave local hardware, the report recommends schema-constrained document extraction, where flat schemas are more reliable and nested outputs are better handled in multiple passes.
For large backlogs, it argues local models can cheaply sort easy cases at scale, but uncertain items should escalate to a larger model or a human rather than be trusted unconditionally.
The broader rule is to use SLMs when privacy, cost, or latency matter and the model is asked to act on supplied text—not supply facts from its own weights.
