| DeepSeek V4 Pro | DeepSeek | $0.000870 | $87.00 | 1,000,000 |
| GPT-5 | OpenAI | $0.00625 | $625.00 | 128,000 |
DeepSeek is one of the cheapest capable APIs available. Compare a DeepSeek model against a GPT model for the same workload and see exactly how much you would save per request and per month.
How this is calculated
We cost the same workload on both models — (input × input price + output × output price) per request, scaled by requests per month — and show the per-request and monthly saving with the exact dollar gap. Change either model to compare any two.
Is this a good result? What to do next
DeepSeek can be 5–20× cheaper per token than flagship GPT models, so the monthly saving is often large. But quality varies by task and there are latency and data-residency trade-offs — compare cost here and test quality on your own prompts.
Typical planning ranges
- DeepSeek vs flagship GPT
- ~5–20× cheaper per token
- Strengths
- reasoning and coding for the price
- Trade-offs
- latency, data residency
Ranges are typical planning figures to sanity-check your result, not authoritative benchmarks. Your numbers will vary with use case, volume, and vendor.
How to improve this number
- Enter your real token mix and volume.
- Use DeepSeek cache-hit pricing for repeated context.
- Validate quality on your prompts before switching.
Common mistakes
- Deciding on price alone without a quality check.
- Ignoring latency and data-residency considerations.
When to use a different approach
To rank all models, use the model cost comparison. For DeepSeek alone, use the DeepSeek API cost calculator.
