LangChain Development FAQs

Common questions about AI development with LangChain

LangChain is a framework for building applications powered by Large Language Models. It simplifies complex AI workflows, provides pre-built components for common tasks, and allows you to create sophisticated AI applications faster. It's the industry standard for LLM development.

RAG (Retrieval-Augmented Generation) combines your proprietary data with LLMs to provide accurate, grounded responses. Use RAG when you need AI to answer questions based on your specific documents, databases, or knowledge bases rather than general knowledge.

Costs vary by model and usage. GPT-4 is more expensive but more capable, while GPT-3.5 is cost-effective for simpler tasks. We optimize costs through smart caching, model selection, and efficient prompting. Typical applications range from $100-$1000/month depending on volume.

Yes! LangChain supports both cloud and on-premise deployments. You can use self-hosted LLMs (like Llama 2) or private cloud instances to ensure your data never leaves your infrastructure. We help you choose the right deployment model for your security requirements.

POCs can be built in 1-2 weeks. Production-ready applications typically take 4-8 weeks depending on complexity. RAG systems are faster to implement than complex AI agents. We deliver iteratively so you see value quickly and can adjust direction as needed.
