Frequently asked questions
Does DeepSeek V4.1 Flash 1017 support image input?
Yes, it supports image input and is a multimodal model.
Does this model have the capability to autonomously invoke external tools?
Yes, the tag explicitly includes 'tools', indicating support for tool invocation.
What is its exact context length?
The context length is 1,000,000 tokens (i.e., on the order of one million).
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
