Why this result
DeepSeek V4 Flash (High) is clearly ahead on the BenchAlign aggregate, 53.95 to 43.87. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeek V4 Flash (High)'s sharpest advantage is in coding, where it averages 68.5 against 27. The single biggest benchmark swing on the page is GPQA, 87.4% to 59%. Ling 2.6 Flash does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
DeepSeek V4 Flash (High) is the reasoning model in the pair, while Ling 2.6 Flash is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. DeepSeek V4 Flash (High) gives you the larger context window at 1M, compared with 262K for Ling 2.6 Flash.
