Editorial note
This brief models deepseek-chat and gpt-4o and claude-sonnet on the same workload so finance and engineering can argue from one spreadsheet row. List prices change; the point is relative ordering and sensitivity to output length. Pair the mini calculator below with your own prompt logs, then export a fuller scenario from the LLM Cost Calculator before you commit spend. Updated 2026-08-16.
- Three-model view covers budget, mid, and premium lanes.
- Embedded calculator is pre-filled for immediate estimates.
- FAQ targets buyers comparing public list prices.
- Re-run after prompt changes — output length shifts monthly $ fast.
Why token calculators diverge
Tokenizer differences and output verbosity change results. Always use the same prompt text and similar max-token assumptions when ranking vendors.
From tokens to budgets
Convert RPS to monthly requests, multiply by tokens per request, then apply list rates. That is the envelope finance can challenge — not a single vague “AI budget” line.
How OmniKit estimates these costs
OmniKit tokenizes representative prompts locally when possible and multiplies by versioned list prices (per million input/output tokens). Traffic is modeled from requests per second and days per month so you can compare vendors on the same workload. Cache write fees, batch multipliers, and enterprise discounts are not assumed unless you set them in the related savings tools.
