With generative AI solutions like ChatGPT gaining immense popularity, CIOs face the challenge of evaluating the total cost of ownership before investing. While interest levels are high, many have concerns about the return on investment.

With generative AI solutions like ChatGPT gaining immense popularity, CIOs face the challenge of evaluating the total cost of ownership before investing. While interest levels are high, many have concerns about the return on investment.

This article breaks down the total cost of a Retrieval Augmented Generation (RAG) chatbot solution. We’ll explore the key costs involved so you can effectively manage budgets.


The main cost categories include:

#3 Deploying Software

RAG solutions require various software like data connectors, chatbots, vector search and large language models. Consider open source vs. commercial options, licensing, security and support costs. Buy vs. Build scenarios should be compared.

Answering the Buy vs. Build Dilemma


The costs add up quickly when companies choose to build solutions themselves. Maintenance, support, operational costs and more create a total cost of ownership (TCO) that is typically 2x higher than leveraging SearchBlox’s dedicated solutions

#4 LLMs

Large Language Model (LLM) costs correlate directly to usage and content volume. Estimating chatbot usage and content needs is key for cost predictability.

#5 Production Support

Effective RAG solutions require ongoing data updates and maintenance. Support costs should account for high user volumes and real-time conversations.

#6 Legal & Compliance

Involve legal and compliance teams early to avoid risks. Auditing capabilities may be required.

#1 Hiring AI Talent

Hiring AI experts or consultants is typically the largest expense. While reskilling employees may save costs, it extends ramp-up time.

Calculate fully-loaded costs for new hires, contractors and training. Note that developing in-house talent can create long-term efficiencies.

#2 Building Infrastructure

Compute, storage and bandwidth costs vary based on factors like:


  • Number of environments (dev, test, production)

  • Latency needs

  • User scale (pilot vs. enterprise)

  • CPU/GPU requirements

  • Data processing and backup needs

  • Large language model requirements


  • Number of environments (dev, test, production)

  • Latency needs

  • User scale (pilot vs. enterprise)

  • CPU/GPU requirements

  • Data processing and backup needs

  • Large language model requirements

Carefully evaluate infrastructure costs during planning.

Engineered for fast, safe deployments — no heavy lifting required.

SearchBlox SearchAI ChatBot handles everything from company policies, processes and precedents to technical troubleshooting and how-to guides. Subject matter experts can focus their time on high-value work rather than repeating the same common questions.


Calculating a 3-5 year total cost of ownership is crucial for RAG solutions. While exciting, generative AI requires strategic planning to manage costs and ensure ROI. Consider all aspects including talent, infrastructure, software, data and support.


With careful evaluation and cost management, organizations can deploy generative AI to deliver true business value.
