DeepSeek V4 Pro API Pricing & Cost Calculator

DeepSeek V4 Pro remains cost-sensitive, but the price is now time-dependent. Schedule flexible workloads off-peak when possible, and model cache hits separately from cache misses instead of applying the old preview rate to every token.

DeepSeek V4 Pro offers industry-disrupting pricing for frontier-level reasoning capabilities.

How this is calculated

DeepSeek V4 Pro's current official API pricing uses UTC peak and off-peak windows. Input cache misses cost $0.66/M off-peak or $1.32/M at peak, output costs $1.98/M or $3.96/M, and cache hits cost $0.022/M or $0.044/M. Off-peak rates are half of peak rates. These rates replaced the April preview prices for the V4-Pro-0813 release.

Verdict

The official V4-Pro-0813 rates are $0.66-$1.32/M for input cache misses, $1.98-$3.96/M for output, and $0.022-$0.044/M for cache hits. A stable prompt receives a 96.67% cache-hit discount in either window, but output tokens are not covered by that discount. For 100K input plus 5K output tokens, the modeled total is $0.0759 off-peak or $0.1518 at peak before any provider-specific fees. Check the official price page before making a long-term budget because DeepSeek reserves the right to change prices.

Frequently asked questions

Does DeepSeek V4 Pro support prompt caching?
Yes. Current official pricing lists cache hits at $0.022 per million input tokens off-peak and $0.044 at peak, versus $0.66 and $1.32 for cache misses. That is a 96.67% discount in either window.
How much does DeepSeek V4 Pro cost per million output tokens?
DeepSeek V4 Pro output costs $1.98 per million tokens off-peak and $3.96 at peak. Cache-hit discounts apply to eligible input tokens, not output tokens, and there is no batch discount listed on the official pricing page.
Is DeepSeek V4 Pro too cheap to be safe?
No, the price reflects vendor economics, not quality compromise. DeepSeek's parent company can offer the rate because of cheaper Chinese infrastructure and a different cost structure. Independent benchmarks show V4 Pro competitive with Claude Sonnet 4.6 and GPT-5.4 on most tasks, often at 5-10x lower cost. The trade-off is geographic data residency and tooling integration.
