Can ChatGPT be trained on company data?

Yes. In most cases the model is not retrained. Instead, the AI integration retrieves answers from your documents and databases at request time, which keeps data current and access controlled.

Is my data safe with the OpenAI API?

We build with vendor zero-retention options, limit what the model can see, and add guardrails and logging. Sensitive workloads can run on private deployments.

Which is better for business, ChatGPT or Claude?

It depends on the use case. We work with OpenAI and Anthropic (Claude) primarily, plus open-source models when data must stay in-house, and recommend per use case.

How long does an AI integration take?

Most AI integrations ship within one 6-week cycle: shaping, prompt and pipeline design, integration, and evaluation against real cases.

Can you add AI to an existing app or system?

Yes. We add AI features to existing web apps and products (React, Next.js, Ruby on Rails), or build standalone AI workflows that connect your current tools.

PROCESS

Software Development Process

STEP 01

Discovery and scoping: problem, budget and solution outline. You get a fixed price before development starts.

STEP 02

Development in a fixed 6-week cycle that ends with working software in production.

STEP 03

Launch, software maintenance, support and the next development cycle.

ChatGPT integration and OpenAI API integration for production

A ChatGPT integration for a business has to work with messy real inputs, stay within a predictable cost per request at volume, and respond safely to unexpected user messages. We build OpenAI API integration and Claude API integration for production use, not proof-of-concept demos.

Every AI integration includes evaluation against your real cases, guardrails on what the model can see and answer, cost controls, and logging so you can audit each response.

AI automation for business: common use cases

The use cases with the highest return: AI data extraction from invoices and contracts, AI document processing for forms and records, drafting the repetitive 80% of customer support replies, summarizing long records for faster decisions, and internal copilots (custom GPT-style assistants) that answer from company documents.

We start by listing where your team spends repetitive hours reading and typing, then build the smallest AI workflow that removes that work. AI consulting for small business and mid-size companies starts with one working workflow, not a long roadmap.

Claude API integration, OpenAI and data privacy

We build on OpenAI and Anthropic (Claude) as primary vendors and keep the integration layer portable, so switching models is a configuration change, not a rewrite. Sensitive workloads can use vendor zero-retention options or run on private deployments with open-source models. Your data stays yours.

FAQ

Frequently asked questions

DevLunch, based in Santo Domingo, works in fixed-price 6-week cycles, so the cost is agreed before work starts. Model usage (OpenAI or Claude API fees) is billed by the vendor separately and depends on volume.
