When it is a good fit
Start with a bounded function with recognisable input and assessable output, such as classifying requests into agreed categories.
OXIAE / INTEGRATIONS & DATA
OpenAI integration.
Integrate OpenAI into your application with controlled inputs, outputs and costs.

What does an OpenAI integration involve?
An OpenAI integration connects an AI model to a specific software function, such as classifying text, extracting data or drafting an answer. Oxiae defines inputs, outputs and error handling, then tests representative examples. The integration fits the product task and the consequences of incorrect results.
When to take a different approach
Do not use generated output without validation for critical system changes. A technically valid response can still be factually wrong.
PRACTICAL DECISION GUIDE
An OpenAI integration needs more than an API call
For an OpenAI integration, I make the application-model contract explicit. What input is sent, which output needs validation and which tools may request actions? The application applies authorization and business checks before a model proposal changes another system. [1]
The chosen API features affect how data and state are handled. We check this for the account configuration and document it alongside error handling, usage limits and cost records. A versioned test set assesses model, prompt or tool definition changes before they affect everyday workflows. [2][3]
Questions to settle first
- Which fields actually need to be sent to the API?
- Which failure or quality issue must block processing?
Make acceptance measurable
- An integration contract with validated output and bounded tools.
- A repeatable evaluation plus checks on failure and data handling.
Compare your options
Choose based on the task, the people involved and what you can maintain.
| Approach | Useful when | What to consider |
|---|---|---|
| Standalone AI tool | Employees perform occasional tasks manually. | Separate from the existing product workflow. |
| API integration | AI belongs in your application or process. | Requires development, access management and operating checks. |
| Multiple model providers | Comparison or fallback options address a concrete need. | Adds testing and behavioural differences. |
What I need to start
- Example input with verifiable expected output.
- Agreement on permitted data processing.
- Usage boundaries and a fallback for model or connection errors.
How to assess the result
- Validate output format and substantive correctness.
- Failures or limits do not silently lose work.
- Track cost and response time per relevant task.
SCOPE & INVESTMENT
What determines the cost?
A useful estimate starts with the scope. I distinguish development work from recurring usage and operating costs. These are the main drivers:
- Function complexity and connected applications.
- Input/output size, model choice and volume.
- Testing, monitoring and model-change maintenance.
APPLICATION AND SCOPE
Your challenge.
A practical application.
Illustrative scenario; not a published client case.
An application needs to classify text, extract information or assist users.
An OpenAI integration uses a specific model provider; LLM integration also considers the choice between providers and models. If answers must use your business information, a RAG system can add sources. This requires permissions, source selection and answer checks in addition to the model call.
THE QUESTION I ASK FIRST
What quality and response time does the intended feature require?
Agree the first step
Use the prerequisites, acceptance checks and cost factors above to define your assignment. Agree who can approve the outcome and who will maintain the solution. The project approach explains discovery, delivery and handover.

Your questions.
Clear answers.
Is API integration the same as using ChatGPT?
No. An API makes AI part of your own software and user flow, requiring your own data, permissions, cost and error controls.
How do you limit integration costs?
Measure cost per task, reduce unnecessary input and duplicate processing, and test whether a simpler model meets the required quality using examples from your application.
