- 03Small models: cheaper, faster, easier to govern
Frontier models are magnificent generalists. For narrow, high-volume, latency-sensitive jobs, they are also overkill.
We routinely see small fine-tuned or well-scoped models beat frontier models on specific tasks — cheaper, faster, and easier to control.
The trick is knowing which jobs qualify. Rule of thumb: if you can describe the task in one sentence and see the pattern in ten examples, a small model can probably do it.
