TCO Evaluation Methodology & Trade-off Analysis

Our multi-dimensional TCO model aggregates fixed infrastructure (Pinecone/Qdrant vector clusters, A100 GPU hosting instances) and variable compute (embedding updates, re-training epochs, input/output token metering). Fine-tuning shines at high query volume (>250k queries/month) where fixed GPU costs amortize rapidly, while Vector RAG provides superior elasticity for rapidly updating corpora.
