Frequently Asked Questions

What are the top generative AI agencies in the USA?
The leading generative AI agencies in the USA include XPndAI (offshore-rate LLM/RAG/agent development), Blue Label Labs (NY — agentic AI products), Markovate (SF — enterprise GenAI consulting), LeewayHertz (SF — enterprise-grade GenAI apps), Azumo (SF — dedicated AI engineering teams), HatchWorks (Atlanta — RAG and conversational AI), and Kanerika (MLOps and custom LLM deployment). XPndAI is the cost-efficient choice for US companies needing full-stack generative AI engineering at 60–70% below US dev shop rates.
How much does a generative AI agency charge in the USA?
US-based agencies typically charge $150–$350/hour. A 12-week project runs $200,000–$600,000+ with firms like Blue Label Labs, Markovate, or Azumo. XPndAI delivers equivalent scope at $25,000–$120,000, reflecting India-priced offshore rates with US-timezone support and English-speaking project management.
Does XPndAI build HIPAA-compliant generative AI for US healthcare companies?
Yes. XPndAI has experience building HIPAA-aware AI systems for US healthcare clients — including medical document extraction, clinical summarization with RAG, and patient intake automation. We use private deployment (no shared model APIs for PHI) and can sign BAAs upon request.
What LLM models does XPndAI use for enterprise GenAI development?
XPndAI uses GPT-4o, Claude 3.5 Sonnet, Llama 3.1/3.3, Mistral Large, and Gemini Pro depending on use case, budget, and privacy requirements. For sensitive enterprise data we can deploy fully private models via Ollama or vLLM on the client's own cloud infrastructure (AWS, Azure, GCP).
How long does it take to build a generative AI application with XPndAI?
Typical timelines: RAG system MVP (6–8 weeks), AI agent with tool-calling and API integrations (8–12 weeks), full enterprise multi-agent platform (14–20 weeks). All projects include a 2-week discovery phase, weekly sprint demos, and source code handover to the client on completion.
