DeepSeek V4 Flash 0731 input price cut, output unchanged
DeepSeek V4 Flash 0731 input pricing has dropped from $0.018 to $0.0104 per 1M tokens, listed on OpenRouter. Output pricing is unchanged at $1.28 per 1M tokens. The change affects the input side only, so the cost profile now leans even more heavily towards what the model generates rather than what it reads.
What it means for a SaaS brand
Cheaper input makes it less costly to stuff large context into a prompt, so expect tools built on this model to retrieve and read more source pages per answer. Make sure your documentation, comparison pages and pricing pages are crawlable and complete, because being retrievable now costs an AI product almost nothing.
