ChatGPT

About Development

ChatGPT is OpenAI's AI assistant, used by hundreds of millions of people every week, and the GPT models behind it are available to businesses through the OpenAI API. Companies use them to add conversational interfaces, automate knowledge work, and build AI agents that act on real data inside their products.

OpenAI's models handle a wide range of tasks out of the box, from writing and summarization to reasoning, coding, and image understanding. Function calling, structured outputs, and the Agents SDK make it practical to connect them to real systems, and enterprise options help teams meet privacy and compliance requirements.

Customer support and sales assistants, internal knowledge copilots, document and contract processing, content generation, data extraction from unstructured text, voice agents, coding assistants, and apps that live directly inside ChatGPT.

OpenAI models work with orchestration frameworks like LangChain and LangGraph, vector databases such as Pinecone and pgvector, and standards like MCP for connecting tools. They're also available through Azure OpenAI for teams that need Microsoft's enterprise controls, and run behind backends built in Python, Node.js, or TypeScript.

OpenAI offers one of the broadest model lineups and ecosystems, with strong multimodal, voice, and agent tooling. Claude is often preferred for long documents and coding, while open-source models can lower costs or keep data fully in-house. Our engineers are model-agnostic and benchmark options against your own use case before committing.

Development FAQs

What can your ChatGPT developers build for our business?

Customer-facing assistants, internal copilots, AI agents, document processing pipelines, voice experiences, and apps inside ChatGPT, all connected to your data and systems.

How do your engineers integrate ChatGPT into an existing product?

They connect your app to the OpenAI API through a secure backend layer, add your business context and data, and set up usage limits, monitoring, and fallbacks before anything reaches users.

How do your engineers keep our data private when using OpenAI?

They design integrations that send only the data each feature needs, use OpenAI's business data controls, and can deploy through Azure OpenAI when stricter compliance is required.

How long does it take to launch a ChatGPT-powered feature?

A focused proof of concept usually takes a few weeks. Production timelines depend on integrations, data sources, and quality requirements.

What does OpenAI consulting from your team include?

Use-case discovery, model selection, prompt and evaluation design, and a cost and latency review, followed by a practical roadmap from prototype to production.
