Choose DeepSeek V4 Pro when cost-per-unit is the priority and your requirements are straightforward; choose Grok 4.5 when reliability, tooling, or ecosystem fit matter more than shaving the per-unit rate.
Beyond price, the two differ on context window (1048576 vs 500000), modalities (text->text vs text+image+file->text) and vision (false vs true). Check those specs against your actual requirements before committing — the cheaper option is only the better deal if it also meets your technical needs.
