Frequently asked questions
How much does DeepSeek-V4.1-Flash cost?
DeepSeek-V4.1-Flash costs $0.030 per 1M input tokens and $0.120 per 1M output tokens, sourced from engy. Cache reads, audio tokens and >200K-context tiers (where applicable) are listed in the Pricing detail block above.
What is the context window of DeepSeek-V4.1-Flash?
DeepSeek-V4.1-Flash has a context window of 1M tokens, with a max output of 128K tokens per reply. This is the total combined size of prompt + completion.
Does DeepSeek-V4.1-Flash support tool calling?
Yes. DeepSeek-V4.1-Flash supports tool calling (function calling). This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Does DeepSeek-V4.1-Flash support structured output / JSON mode?
Yes. DeepSeek-V4.1-Flash supports structured output / JSON-schema-constrained decoding. This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Can DeepSeek-V4.1-Flash accept image input?
Yes. DeepSeek-V4.1-Flash accepts both text and image input. Vision pricing per image is usually billed on top of the regular token rate — check DeepSeek's docs for the exact rule.
