Rationale
- Input and output prices moved in opposite directions: Total costs decreased for read-heavy, write-light tasks (long-document Q&A, codebase retrieval, long-context agents), while long-output tasks became more expensive
- OpenRouter's introduction describes this as a post-trained version of DeepSeek V4 Flash, targeting programming, reasoning, and agentic workflows
Usage
- On OpenRouter, use the model ID deepseek/deepseek-v4-flash-0731; estimate whether it is cheaper based on your task's input/output ratio, and refer to the official DeepSeek pricing page for direct API access
Risks
- OpenRouter list prices are from a third-party aggregation platform and may change again with supplier switches, differing from official direct API prices
