Frequently Asked Questions About OpenAI Development

What is OpenAI development?+
OpenAI development is the process of building software applications that use OpenAI's GPT models, embeddings and APIs to automate tasks, generate content, analyse data and deliver intelligent user experiences.
Which OpenAI models do you work with?+
We work with GPT-4o, GPT-4, GPT-3.5, OpenAI embeddings, DALL-E and the Assistants API — selecting the right model based on accuracy, latency and cost requirements.
Can you integrate OpenAI into our existing product?+
Yes. We integrate OpenAI into SaaS platforms, CRMs, ERPs, internal tools and customer-facing applications via APIs, SDKs and embedded copilot interfaces.
Do you support Azure OpenAI?+
Yes. We deploy and integrate Azure OpenAI Service for enterprises requiring data residency, private networking and Microsoft compliance frameworks.
How do you reduce OpenAI API costs?+
We implement prompt optimisation, response caching, model routing (using smaller models where appropriate), token limits and usage monitoring dashboards.
Can you build RAG with OpenAI?+
Yes. We build retrieval-augmented generation systems using OpenAI embeddings, vector databases and GPT for accurate, context-grounded responses.
How do you handle AI safety and hallucinations?+
We implement output validation, content filtering, confidence scoring, source citation and human-in-the-loop review workflows to minimise hallucinations and unsafe outputs.
Do you fine-tune OpenAI models?+
Yes. We fine-tune OpenAI models on your domain-specific data to improve accuracy for specialised terminology, formats and business logic.
How long does an OpenAI project take?+
A focused OpenAI integration or PoC typically takes 4–8 weeks. Full enterprise copilot or knowledge platform projects take 3–6 months depending on scope.
Do you provide ongoing OpenAI support?+
Yes. We provide model monitoring, prompt iteration, cost optimisation and feature enhancement as part of ongoing support agreements.
