Frequently Asked Questions
What is AI agent development?
AI agent development involves building autonomous AI systems that can plan, reason, and execute multi-step tasks without human intervention. Unlike simple chatbots, AI agents use LLMs to make decisions and complete complex workflows automatically.
How much does AI integration cost in India?
AI integration typically costs ₹1.5L–₹8L for small to mid-size businesses. ROI is usually seen within 3–6 months through reduced manual work and increased efficiency.
What is the difference between RAG and fine-tuning?
RAG (Retrieval-Augmented Generation) connects AI to your existing documents for real-time answers. Fine-tuning trains a model on your data. For 90% of businesses, RAG is faster, cheaper, and more effective.
How long does AI integration take?
A basic AI integration takes 2–4 weeks. A full agentic workflow system takes 6–10 weeks. We start with a free consultation to assess your specific needs.
Which AI models do you integrate?
We work with GPT-4o, Claude 3.5, Gemini, and open-source models like Llama. Model selection depends on your use case, budget, and data privacy requirements.
