That analysis is unfortunately running DeepSeek on Max. DeepSeek recommends against that since it guarantees higher cost and rarely improves the outcome- it should be ran on "high".
Their coding page shows DeepSeek Max as Pareto optimal: https://artificialanalysis.ai/agents/coding-agents Costing 1/2 of Terra Xhigh. It would also be great to see Sol and Opus not on max there.
Not a useful benchmarking site for coding unless you only want to run your models on Max.
