OpenAI API, a state-of-the-art AI engine integrated cleanly

The OpenAI API provides access to the most advanced language models on the market: GPT-4o, o1, vision and audio models. It handles text, images, voice and embeddings in a coherent interface, with native function calling and structured outputs.

At Inprogress, we integrate the OpenAI API into production products. We master prompt engineering, cost control, hallucination detection and fallback patterns for integrations that go beyond the prototype.

Module: 01

The benefits of the OpenAI API

01

Cutting-edge models, continuously updated

Versions evolve regularly: better quality, new capabilities (vision, audio, reasoning), falling costs. You benefit from progress without rework.

02

Unified multimodality

One provider for text, images, audio and embeddings. Fewer integrations, more consistency across AI features.

03

Production-ready tooling

Function calling, structured JSON outputs, persistent assistants: the ecosystem lets you go beyond simple prompts to build reliable apps.

Why Inprogress?

Prioritization

We help you decide quickly what should be built now and what should wait.

Quality

We enforce technical quality to prevent slowdowns and avoid product debt.

Speed

A product should move continuously, with a delivery rhythm the whole team can trust.

Frequently asked questions

We start with a fast audit of product context, codebase and business priorities.

Then we run a shared backlog with short iterations and frequent deliveries.

Yes. We audit the current stack, fix critical issues and restore delivery flow.

The objective is to stabilize quickly without freezing your roadmap.

Yes. We act as an extension of your team with transparent technical steering.

Decisions, backlog and rituals are shared end to end.

We plan costs from scoping: volume estimation, model selection (GPT-4o vs mini), response caching, prompt compression, production monitoring.

The goal is a readable bill that grows predictably with usage.

Grounding on your data (RAG), structured outputs to constrain responses, automatic validation, human fallback when confidence is low.

A reliable AI integration combines multiple guardrails, not blind trust in the model.

Each provider has its strengths. OpenAI shines on multimodality and tooling, Anthropic on long-form reasoning and safety, Mistral on European sovereignty.

We decide based on your product, regulatory and budget constraints, and design abstraction layers to limit lock-in.
