FAQ
Do I need to provide my own API key?
Yes — you'll need an OpenAI or Anthropic account with API access. I'll guide setup if needed and help estimate monthly costs upfront.
Which model should I use — GPT-4o or Claude?
I'll help you choose based on your use case. GPT-4o-mini for speed and cost, Claude 3.5 for complex reasoning, Claude Haiku for cheap batch tasks. We discuss before starting.
Will this work with my existing stack?
I work with Next.js, React, Node.js, Python, and FastAPI. If you use another stack, message me first with details and I'll tell you honestly if it's a fit.
Can you also deploy it for me?
Yes — deployment is included in the Premium package (Vercel/Railway/etc). For Basic/Standard, I deliver working code that you or your team can deploy.
