Building on OpenAI models: what a GPT developer actually does
Most searches for "GPT-3 developers" or "GPT-4 developers" are really looking for the same person: an engineer who can turn OpenAI's current model family into a product feature that works reliably. The model names move every year, so the mistake buyers make is hiring for a version instead of for the craft. Anyone can call the API once. The hard parts are grounding answers in your data, controlling cost and latency, handling tool calls and structured output safely, and proving quality with evaluations instead of vibes. Hyparz vets GPT developers on those production skills, then matches you with a pre-vetted remote engineer, typically within days, with a one-week risk-free trial.
Prompting is the easy part
Senior work on OpenAI models looks like software engineering, not prompt tinkering. It means choosing the right model tier for each call (a reasoning model for hard planning, a small fast model for classification), enforcing structured JSON output so downstream code never parses prose, designing function and tool calling so the model can act on your systems, and building retrieval so answers cite your documents rather than guessing. It also means a test harness: a fixed set of real inputs, scored automatically, run before every prompt or model change.
Where an OpenAI-based build pays off, and where it does not
GPT-family models earn their place in support assistants grounded on your knowledge base, document extraction and summarisation, agents that call internal APIs, code generation inside your own tooling, and content workflows with a human in the loop. They are a poor fit when the task is a simple classifier that a small fine-tuned model can do for a fraction of the cost, when data cannot leave your environment, or when outputs must be deterministic. A good GPT developer will tell you when a cheaper approach wins.
Our vetting for OpenAI application engineers
We give candidates a realistic feature, for example an assistant that answers questions over a messy document set, and look at how they ground it, how they handle hallucination and refusal cases, whether they stream responses and cache where it saves money, and how they evaluate the result. We also check they can migrate between model versions without rewriting the product, because the model you launch on will not be the model you run in a year.
