Yes, We will provide you appropriate suggestions for making your project successful with our experience.
What LLM providers do you support?
I work with all major LLM providers including OpenAI (GPT-4o), Google Gemini, Anthropic Claude, and open-source models like LLaMA and Mistral. I'll recommend the best one based on your budget and use case.
Will I receive the full source code after delivery?
Yes, absolutely. You will receive the complete source code, project files, and a README with setup instructions. You'll have full ownership of everything delivered.
Can you integrate the AI into my existing website or app?
Yes. I can integrate AI features into your existing platform whether it's built on React, Next.js, or a custom stack. Just share your current tech setup when you reach out and I'll confirm compatibility.
What if I need changes after the project is delivered?
Revisions are included in every package. For changes beyond the agreed scope, I offer affordable post-delivery support. I'm always available via Fiverr messages to discuss any updates you need.
Do I need to provide my own API keys (e.g. OpenAI)?
Yes, you'll need to provide your own API keys for LLM providers like OpenAI or Google Gemini. This keeps your data private and gives you full control over usage and billing. I'll guide you through the setup if needed.
