CC Switch v3.19.1 Enables Direct DeepSeek-V4-Flash Codex Integration

CC Switch v3.19.1 allows native DeepSeek-V4-Flash invocation in Codex via API key, removing backend proxy requirements. V4-Pro integration remains pending until August.

Woofun AI reports that CC Switch has released version 3.19.1, adding native support for the DeepSeek-V4-Flash Responses API. Users can now input their DeepSeek API Key to directly invoke this model within Codex, eliminating the need for local routing or backend proxies previously required to convert interface formats. Currently, this direct connection method is exclusive to V4-Flash. The V4-Pro model continues to rely on the older routing mechanism, with DeepSeek expected to add Responses API support for it in early August.
