FAQ
Which AI models do you work with ?
I mainly integrate OpenAI and Anthropic Claude models. I can recommend the most suitable model based on your feature, expected usage, speed requirements, context size and operating budget.
Will this work with my existing website or app ?
Usually, yes. I mainly work with Next.js, React and TypeScript applications, but I can also connect an AI backend to other platforms through secure APIs. Please send me your current stack before ordering.
Do I need my own API key ?
Yes. For production use, the API account and billing should belong to you. I will integrate the key securely through server-side environment variables so it is never exposed in the browser.
How much does the AI API cost to run ?
API usage is billed separately by the AI provider and is not included in the gig price. The cost depends on the selected model, the amount of text processed and the number of users. I can help you choose a cost-efficient setup.
Can you integrate AI with my private data or documents?
Yes. I can build document search, knowledge-base assistants and RAG features using your database or uploaded content. The exact architecture depends on your data volume, format and privacy requirements.
Is the OpenAI or Claude subscription included?
No. ChatGPT or Claude consumer subscriptions are separate from API usage. You will need an API account with the selected provider and will pay usage costs directly to them.
