Editorial note
This brief models 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 2026-07-26.
- Both models are optimized for high QPS chat and classification workloads.
- DeepSeek Chat often undercuts GPT-4o mini on output tokens — watch completion-heavy apps.
- Latency and provider reliability should be evaluated separately from list price.
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.
Use this page for directional planning, then confirm with your provider invoice and a quality eval on your domain. For a full planning path, see the LLM cost planning guide. Last verified against catalog v2026-09-11 (page checked 2026-07-26).

FAQ
Which model is better for customer support bots?
Price favors DeepSeek Chat in many regions, but choose based on eval quality on your tickets. Run both through the calculator with your real system prompt.
Can I mix providers?
Yes. Many teams route simple turns to the cheaper model and escalate hard cases — model monthly cost for each tier separately.
What traffic assumption should I use?
Convert daily conversations into average requests/sec over peak hours, then annualize with the calculator's monthly projection.
