DeepSeek V4 Pro

DeepSeekopen-sourceOpen Source-75%

The cheapest frontier-class model on the market, and not by a small margin. 1.6T MoE / 49B active, MIT-licensed weights on Hugging Face, 1M context, 384K max output. DeepSeek launched it at $1.74/$3.48, cut prices 75% as a promotion, then made the cut permanent on 31 May 2026 — so the standing rate is $0.435 input / $0.87 output per 1M tokens, with cache hits at $0.003625. On Artificial Analysis's blended 7:2:1 basis that works out to about $0.18 per 1M tokens against $0.90 for GLM-5.2 and $2.31 for Kimi K3; measured cost-per-task is roughly $0.04 versus $0.94 for K3, a 23x gap. Quality is genuinely frontier-adjacent rather than budget: 80.6% on SWE-bench Verified (matching Gemini 3.1 Pro) and 83.5 on MRCR 1M. One dollar buys about 1.15M output tokens here versus 67K on Kimi K3.
