DeepSeek V4 Flash is the fast, low-cost tier of DeepSeek's V4 model family, introduced in April 2026 as a smaller mixture-of-experts sibling to V4 Pro. DeepSeek has since retired the original V4-Flash on its own API and keeps the deepseek-v4-flash name temporarily, routing it to DeepSeek-V4.1-Flash. ATP's catalog exposes this id with tool calling and image input, without thinking mode.

Where it fits

Good fit
  • Bulk extraction, classification, and tagging jobs
  • High-QPS chat, summarization, and RAG answer generation
  • Fast tool-calling agent steps that need 1M-token context headroom
  • Reading screenshots, charts, and document images alongside text
Usually not ideal
  • Thinking-mode reasoning — ATP's catalog exposes the non-thinking path here; use deepseek-v4-pro for depth
  • Workloads that must pin one exact model build — DeepSeek upgrades the model behind this name in place

Same controls on every model: project keys, per-project model access, credit budgets, and a log of every request.Set up your organization
