Frequently asked questions
No, DeepSeek V4 Pro is cheaper for the typical workload above. At $0.435/1M input and $0.870/1M output tokens, it costs $0.3915 versus $0.7130 for DeepSeek R1 — a 45% difference.
DeepSeek R1 supports a 128K token context window. DeepSeek V4 Pro 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.
DeepSeek R1 does not support context caching. It does not offer a batch API discount. DeepSeek V4 Pro supports context caching (99% off repeated tokens). It does not offer a batch API discount.
Yes, both DeepSeek R1 and DeepSeek V4 Pro use the SentencePiece (Llama). The same text produces identical token counts on both models, so any cost difference is purely due to the rate each provider charges per token.
DeepSeek R1 (DeepSeek): $0.55 input / $2.19 output per 1M tokens. DeepSeek V4 Pro (DeepSeek): $0.435 input / $0.87 output per 1M tokens. Rates shown before caching or batch discounts.
For an 80% output / 20% input workload — typical for code generation or long-form writing — DeepSeek R1 costs $1.8620 per 1M total tokens and DeepSeek V4 Pro costs $0.7830. DeepSeek V4 Pro is 58% cheaper for this pattern. For your exact ratio, paste a real prompt into the calculator above.
