Adding a language model to a product that already exists — without a rewrite, a runaway bill or output nobody can parse.
Four areas where this work is won or lost.
Where a model genuinely helps — drafting, summarising, extracting, classifying — and where plain code is better and cheaper.
Responses forced into a schema and validated, so downstream code receives data rather than prose.
Caching, model routing and prompt budgets, because an unmetered model call is a recurring line on the invoice.
Provider failover, timeouts and content rules, so an outage or a bad response degrades gracefully.
A short loop with a written result at every step.
We map candidate features against value and error tolerance and pick the one that earns its running cost.
A thin internal interface over the provider, so the model can be swapped without touching product code.
Per-feature cost, latency and quality tracked, with a budget alert before the invoice surprises you.
Chosen for your product, not for our habit.
Tell us what the product does today. We will point to the feature that earns its model bill.
