Editorial note
This brief models gpt-4o and gpt-4o-mini and deepseek-chat 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.
- OpenAI offers multiple tiers — mini vs 4o changes the story completely.
- DeepSeek Chat is the usual low-cost anchor in OmniKit's catalog.
- Compare at least two OpenAI SKUs before declaring a winner.
- Re-run after prompt changes — output length shifts monthly $ fast.
Ecosystem versus unit cost
OpenAI often wins on tooling familiarity, SDK coverage, and partner integrations. DeepSeek frequently wins on published per-million rates for text chat. Your decision should weight both — a cheaper model that needs more retries or longer outputs can erase savings.
Planning tip
Build a blended router: cheap model for bulk classification, premium model for hard cases. OmniKit’s Model Router Recommender helps sketch that blend before you write code.
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.
