How this comparison was made

Method and test inputs

This comparison checks the current public model catalog record, the Vizify app-profile model allowlist, and the existing /models/deepseek/ page for both variants. It does not run independent prompts through DeepSeek V4 Flash or DeepSeek V4 Pro to score response quality, and it does not reference any external benchmark.

Choosing

Which one fits your task

Option A

DeepSeek V4 Flash

The Paid-tier DeepSeek V4 variant currently available in Vizify with Pro or a credit pack purchase.

  • Switching models with Pro or a credit pack purchase
  • General text drafting and structured Q&A
  • Trying the DeepSeek family before deciding on Pro access

Choose DeepSeek V4 Flash to try that variant with paid model access, or DeepSeek V4.1 Flash for the newer Flash model.

Option B

DeepSeek V4 Pro

The Paid-tier DeepSeek V4 variant currently available in Vizify for accounts with current Paid-model entitlement.

  • Continuing with DeepSeek V4 once Paid-model entitlement is enabled
  • Text-only tasks where you want to stay in the DeepSeek family at the Paid tier
  • Switching to DeepSeek V4 Pro from another Paid model mid-conversation

Choose DeepSeek V4 Pro if your account already has current Paid-model entitlement and you want to keep using the DeepSeek family.

Before you rely on this

Current limitations

  • This comparison is based on the Vizify public model catalog and app profile reviewed on 2026-09-26, not an independent quality or reasoning benchmark.
  • Flash and Pro share identical input and output modality support in Vizify's catalog, and both require paid model access.
  • DeepSeek V4.1 Flash, the successor to V4 Flash, is not compared on this page.
  • Vizify sends each request to one selected model; it does not run Flash and Pro in parallel or merge their answers.
  • Paid-model entitlement, credit requirements, and tier assignment are set independently of this page and can change without updating this comparison.

DeepSeek V4 Flash and DeepSeek V4 Pro both require paid model access in Vizify. Both accept text and produce text. This page describes their supported inputs and product access, without claiming a performance ranking between them.

With paid access, both are available from the same model picker, and you can switch between them without starting a new conversation or losing existing artifacts.

DeepSeek V4 Flash now has a successor, DeepSeek V4.1 Flash, with the same Paid tier and text-only input at a higher credit rate. V4 Flash stays available, so this comparison still applies if you want to keep using it.

Because both variants share one dedicated model page (/models/deepseek/), you can review tier and input details for both in one place before switching between them for a later request in the same Vizify workspace.
