Real-world cost example
1,000 API requests per month, each with 500 input tokens and 200 output tokens (500K input + 200K output total).
DeepSeek V3
$0.3550
Input: $0.1350 + Output: $0.2200
GPT-4.1
$2.6000
Input: $1.0000 + Output: $1.6000
DeepSeek V3 is 86% cheaper for this workload — saving $2.2450 per month at this volume.
Frequently asked questions
- Is DeepSeek V3 cheaper than GPT-4.1?
- Yes, DeepSeek V3 is cheaper for the typical workload above. At $0.270/1M input and $1.10/1M output tokens, it costs $0.3550 versus $2.6000 for GPT-4.1 — a 86% difference. Costs scale linearly, so larger workloads amplify this gap.
- What is the context window of DeepSeek V3 vs GPT-4.1?
- DeepSeek V3 supports a 128K token context window. GPT-4.1 supports a 1M token context window. A larger context window lets you include more text — documents, conversation history, or code — in a single API call.
- Do DeepSeek V3 or GPT-4.1 support context caching or batch discounts?
- DeepSeek V3 does not support context caching. It does not offer a batch API discount. GPT-4.1 does not support context caching. It offers a 50% Batch API discount.
