Complete guide to using DeepSeek V4 Flash API
deepseek-v4-flash. DeepSeek documents it as a fast, economical V4 API model with 284B total parameters and 13B active parameters.DeepSeek V4 Preview is officially available with 1M context and separate Flash and Pro profiles.
01
DeepSeek V4 uses a mixture-of-experts profile. Official docs list DeepSeek V4 Flash at 284B total / 13B active, giving teams a clear separation between the efficient Flash route and the stronger Pro route.
02
DeepSeek describes V4 Flash as closely approaching V4 Pro reasoning, matching Pro on simple agent tasks, and using a smaller active profile for faster response times and lower API cost.
03
The official DeepSeek release notes state that 1M context is the default across official DeepSeek services. This is useful for long chats, repository-scale coding context, large documents, and multi-step agent memory.
04
DeepSeek documents dual modes for the V4 API family. Use non-thinking for faster direct answers and thinking mode for tasks where explicit reasoning effort improves quality.
Route common assistant, support, and Q&A traffic to the economical Flash profile.
Use Flash for code explanations, simple edits, test ideas, and quick debugging loops.
Use 1M context for large documents and knowledge packets without aggressive chunking.
Let Flash handle simple planning and tool-use paths before escalating harder work to Pro.
Both Model IDs come from the same DeepSeek V4 Preview API family. Choose Flash for efficient traffic and Pro for harder reasoning, coding, and agent work.
