DeepSeek V4 Pro

DeepSeek V4 Pro is the larger reasoning checkpoint: 1T parameters, a 1M context window, and text plus image input. Published scores on record here are 92.4% GPQA Diamond and 93.5% LiveCodeBench. Reach for it when Flash has already missed a hard math, logic, or competitive-coding problem. It is slower and more expensive per call than Flash, so it is a poor default for routine edits.
