Model Cost Comparison · Built by Lazige · Methodology

How we calculate cost

Monthly estimate = (input tokens × input $/MTok) + (cached tokens × cached $/MTok when published) + (output tokens × output $/MTok), scaled to your message volume. See the methodology for validation sources and update cadence.

Use cases

Common workload patterns teams model here

Illustrative scenarios — not customer testimonials. Each card shows how a typical team shape (support bot, RAG, code assistant, or agent) maps to the calculator presets.

“A support-bot preset with 50k messages/month surfaced three budget models in one pass — faster than copying rates from five pricing pages.”
B2B SaaS support botHigh volume · short replies · 55% cache
“Raising the cached-input slider made our RAG estimate realistic. We moved retrieval-heavy traffic to a cheaper model without changing reply quality.”
Document Q&A / RAGRetrieval-heavy · 65% cache
“PMs use the embed on internal docs to sanity-check model spend before vendor requests — everyone shares the same workload baseline.”
Platform / internal toolingMixed presets · stakeholder decks
“Before scaling an agent workflow, comparing monthly cost across every provider for the same token mix avoided over-provisioning on day one.”
Tool-calling agentAgent preset · multi-step I/O
“Finance teams grasp token mix faster with one screenshot from the ranking table — useful when justifying a move off a default premium model.”
Cost review / FinOpsBoard prep · usage doubles scenario
“Quarterly Bedrock vs Vertex vs direct API reviews start here — normalize the math before opening vendor spreadsheets.”
Cloud architecture reviewMulti-cloud comparison
“The code-assistant preset was a realistic starting point for a copilot MVP; we adjusted tokens after a pilot week and stayed within 10% of the estimate.”

“Gemini Flash placed top three for our exact cache ratio on a high-volume FAQ bot — easy to miss in a static pricing table.”
