Hidden Costs Breakdown

LLM API Costs

high overage

Operational costs for LLM API calls, such as GPT-4o, for evaluations and test set generation.

industry
A RAG pipeline can incur LLM API costs ranging from $100-$2,000 per month at Minimum Viable Product (MVP) scale, escalating to $1,000-$10,000+ per month at production scale.

Embedding Generation

medium overage

Costs for generating embeddings, which can accumulate, especially with re-embedding due to model changes or chunking strategy.

industry
Embedding a million documents at 500 tokens each costs approximately $10 with this model.

Data Cleaning & Preprocessing

critical implementation

The most underestimated cost, accounting for 30-50% of the total project cost, involving formatting, deduplication, and quality checks for documents before embedding.

industry
Data Cleaning & Preprocessing: This is often the most underestimated cost, accounting for 30-50% of the total project cost.

Custom Chunking Strategy Development

high implementation

Optimizing how documents are split for retrieval, which significantly impacts RAG quality.

industry
Custom Chunking Strategy Development: Optimizing how documents are split for retrieval significantly impacts RAG quality and can cost between $2,000 and $5,000.

Hybrid Search Implementation

high implementation

Combining vector search with keyword search to enhance accuracy, which adds complexity.

industry
Hybrid Search Implementation: Combining vector search with keyword search enhances accuracy but adds complexity, typically costing $1,500-$3,000.

Metadata Filtering

medium implementation

Designing schemas for filtering by date, department, or document type.

industry
Metadata Filtering: Designing schemas for filtering by date, department, or document type can cost $1,000-$2,500.

Re-Indexing Costs

high overage

Costs associated with updating documents, necessitating re-embedding and re-indexing.

industry
For a 1 million-chunk corpus, engineering time for re-indexing can range from $3,000 to $10,000 over 3-10 days.

Prompt Engineering & Iteration

medium implementation

Expert time required to correctly configure RAG prompts.

industry
Prompt Engineering & Iteration: Getting RAG prompts right requires 15-30 hours of expert time, translating to $1,800-$3,600.
