LLM Development Company & ChatGPT Integration Services

LLM Development

LLM development and ChatGPT integration for the apps you already have

We're an LLM development company. We add ChatGPT-style features to your web apps, mobile apps, ERPs and CRMs: summaries, drafting, smart search and image generation. For sensitive data, we build private LLM solutions that run where your data rules require.

What LLM integration means

ChatGPT-style features, inside your own software

Your team already uses ChatGPT for drafting and summaries, by copying text in and out. LLM integration puts those abilities inside the apps they work in, connected to your data, with the right permissions.

We integrate models from OpenAI, Anthropic, Google and the open-source world through their APIs, choose the one that fits each task, and test the results before your users see them.

FAQ

Questions about LLM Development and ChatGPT Integration

Ask us something else
What does an LLM development company do?

An LLM development company builds products and features on large language models. We choose the right model, design prompts and tools around your data, integrate it into your apps and test the results before launch.

What do ChatGPT integration services include?

We connect your app, ERP or CRM to the OpenAI API, or another model's API, and build the features your users need: summaries, drafting, search or image generation, with your data and permissions.

What is a private LLM?

A private LLM is a language model that runs in your own cloud or on your own servers, so your data never goes to an outside AI provider. We deploy open-source models for this when your data rules require it.

Do we need LLM fine-tuning?

Usually not. Good prompts and retrieval solve most use cases. We recommend fine-tuning only when tests show a clear gain in quality, cost or speed.

Can I hire LLM developers for my team?

Yes. You can hire our LLM developers to build a new feature, or to work alongside your developers on one you've already started.

How long does an LLM integration take?

Adding one GenAI feature to an app usually takes 2 to 4 weeks. A wider integration or a private LLM deployment usually takes 6 to 10 weeks.
