FAQ
Which LLM should I use — GPT-4o, Claude, or Gemini?
Depends on your use case. GPT-4o is best for general tasks and function calling. Claude is better for long context and nuanced reasoning. Gemini Flash is cheapest for high-volume. I'll recommend based on your requirements before you order.
Can you work with my existing codebase?
Yes. Share your repo or a description of your stack and I'll integrate the LLM into your existing structure — no rewrites unless you want them.
Do you handle API key security?
Absolutely. All keys go in environment variables, never in code. Standard and Premium include a secrets management guide for production deployment.
What about rate limits and cost control?
Standard and Premium include token usage tracking, retry logic with exponential backoff, and caching where it makes sense. Premium adds a full monitoring dashboard.
Can you build AI agents or multi-step workflows?
Yes — included in Premium, or available as an extra on Basic/Standard. I've built multi-step pipelines with tool calling, memory, and fallback logic.
Do you provide the prompts or do I?
Either works. If you have prompts, I'll optimize them. If not, I'll write and test prompts tuned to your use case — this is included in all packages.
What if the integration breaks after delivery?
All packages include revisions. For production issues beyond revisions, I offer post-delivery support at an hourly rate — just message me.
Can you integrate open-source models like Llama or Mistral?
Yes — via Groq, Together AI, Replicate, or self-hosted (Premium only, as self-hosting needs infra setup).
