About AI Model Cost Comparison Calculator
AI API costs vary by more than 150x across providers and model tiers. A workload costing $15,000/month on Claude Opus 4.8 may cost under $100 on DeepSeek V4 Pro. Understanding per-request, daily, monthly, and yearly costs across the major model families enables informed model selection — picking the cheapest model that still meets quality requirements for a given task tier.
How It Works
The calculator multiplies token counts by each model's published per-million-token price for inputs and outputs separately, then sums them. Daily cost scales by requests per day, monthly by 30 days, yearly by 365. Model selection checkboxes let you narrow the comparison to relevant options. The bar chart normalises all monthly costs to the maximum to show relative scale at a glance, with cheapest and most expensive models highlighted.
Who Is This For
A startup CTO evaluating which model to use for a customer support chatbot processing 5,000 conversations per day — the calculator shows the exact monthly delta between Sonnet 4.6 and Haiku 4.5.
A solo developer building a document-processing pipeline who needs to justify the premium of GPT-5.5 over DeepSeek V4 Pro to their client — the yearly cost comparison makes the tradeoff concrete.
A platform team benchmarking Enterprise workloads (100K req/day) where a $0.01/request difference compounds to over $36,000/year.
A product manager choosing between Gemini 3.5 Flash and Gemini 3.5 Pro — instantly sees the cost multiple for their specific input/output token mix.
