|---|---|---|---|---|
| Input-heavy / RAG | 5M input + 500K output | R1 | $7.7 | $4.75 |
| Balanced workload | 1M input + 1M output | R1 | $5.5 | $3.2 |
| Output-heavy chatbot | 1M input + 5M output | R1 | $23.1 | $13.2 |
R1 is $1.9 cheaper per 1M output tokens (43.2% lower; 1.76x difference).
o3 Mini has 36.16K more context (1.22x larger).
R1 is $1.35 cheaper on the standard workload (40.9% lower).
Estimate your workload cost
Your Workload Cost
This estimate uses normalized public API pricing per 1M tokens. It is a planning aid, not a billing quote. Verify provider pricing, limits, and terms before production use.
Quick Decision
R1 has the lower input price; R1 has the lower output price; o3 Mini offers the larger context window. For the 1M input plus 500K output sample, R1 is cheaper for the standard workload.
For a 1M input token plus 500K output token workload, the estimated API cost is $3.3 for o3 Mini and $1.95 for R1.
Choose o3 Mini when you care most about larger context window.
Choose R1 when you care most about lower input-token price, and lower output-token price.

Use-Case Decision Matrix
| Use case | Better pick | Why |
|---|---|---|
| Budget-constrained production | R1 | On the standard 1M input plus 500K output workload, R1 is estimated at $1.95 vs $3.3 for o3 Mini, saving $1.35 (40.9% lower). |
| High-volume input processing | R1 | Lower prompt-token price matters most when prompts, retrieved passages, or documents dominate the bill. |
| Long responses and chatbots | R1 | Lower output-token price matters most when assistants generate many completion tokens. |
| RAG or long-document work | o3 Mini | A larger context window leaves more room for retrieved passages, conversation history, or source files. |
