DeepSeek V4 Pro 0813 vs GPT-4.1
DeepSeek V4 Pro 0813 leads GPT-4.1 on the Artificial Analysis Intelligence Index, 36.0 to 12.7, and DeepSeek V4 Pro 0813 costs 4.0x less per output token ($1.98 vs $8.00 per million). Updated October 22, 2026; 47 benchmarks have a result for both.
DeepSeek V4 Pro 0813 or GPT-4.1: which to pick
Only DeepSeek V4 Pro 0813 has a coding score, 56.1 on the Vibe Coding Index; GPT-4.1 has none, so the two cannot be ranked on coding.
Pick GPT-4.1 for work measured by LegalBench (Vals AI) or TaxEval (Vals AI), where it leads.
