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.

Current limitations

  • This comparison is based on the Vizify public model catalog and app profile reviewed on 2026-08-16, not an independent quality or reasoning benchmark.
  • Flash and Pro currently share identical input and output modality support in Vizify's catalog, so the only verifiable difference documented here is access tier.
  • 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 are the two DeepSeek variants Vizify currently exposes, and the catalog draws a clear line between them: Flash sits in the Basic tier, Pro sits in the Paid tier. Everything else Vizify can verify — text-only input, text-only output, no image support yet — is identical between the two, so tier access is the practical decision point rather than a difference in what each model can accept.

If your account doesn’t have current Paid-model entitlement, Flash is the way to try the DeepSeek family today. Once Paid access is enabled, Pro becomes available from the same model picker without starting a new conversation or losing existing artifacts.

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.
