Reddit user Few_Painter_5588 reports that DeepSeek has soft-retired V4 Pro, potentially narrowing model availability for deployments that depend on that variant.

What is this?

DeepSeek V4 Pro is described in the supplied third-party snippets as an open-weight mixture-of-experts model from DeepSeek, released alongside the smaller V4 Flash for reasoning, software engineering, and agentic tasks. The case cites a Reddit user's report of V4 Pro being “soft-retired” and an attributed staff statement that V4.1 Flash outperforms it, but the supplied search snippets do not substantiate either claim or establish reduced availability. Instead, they describe V4 Pro API access through multiple providers; the explicit retirement notice concerns the legacy aliases deepseek-chat and deepseek-reasoner, not V4 Pro itself. The search answer's categorical retirement claim therefore exceeds the supporting snippets, and any effect on dependent deployments remains unverified.

Why it matters to Scott

Scott’s Model Perishability page already argues that rapid model replacement requires swappable dependencies; this report offers only an unverified example, not a substantiated availability change or a consequential party adopting his position. The hits establish no Scott dependency on V4 Pro, and although the radar tracks analogous Copilot deprecations, it does not establish prior coverage of this specific development.
