Frequently asked questions
How much does DeepSeek V4 Flash cost per 1M tokens?
DeepSeek V4 Flash costs $0.140 per million input tokens and $0.280 per million output tokens at DeepSeek list prices. Output is 2.0x the input rate, so the input:output ratio of your workload drives the real cost more than the headline price.
Does DeepSeek V4 Flash support prompt caching?
Yes. Cached input is billed at $0.00280 per million tokens, 50x cheaper than uncached input. There is no cache-write premium, so caching is never a net loss.
What is the batch discount for DeepSeek V4 Flash?
DeepSeek V4 Flash does not offer a batch pricing tier.
What is DeepSeek V4 Flash's context window?
1.0M tokens of context with up to 384K output tokens per request. A larger context window raises the ceiling on what you can send, not the price per token — but filling it on every request is one of the most common causes of an unexpected bill.
