DeepSeek V4 Flash 0731 input price cut, output unchanged
Input pricing for DeepSeek V4 Flash 0731 has moved from $0.01 to $0.0089 per 1M tokens, as listed on OpenRouter. Output pricing is unchanged at $1.28 per 1M tokens. The cut applies only to the input side, so the cost profile shifts for input-heavy workloads.
What it means for a SaaS brand
Cheaper input tokens make it slightly less costly to push large context, such as full docs pages or long product comparisons, into retrieval and summarisation pipelines built on this model. Output still carries the cost, so the economics favour feeding in more source material rather than generating longer answers.
