Pairwise benchmark snapshot · Aug 17, 2026noindex (thin pair)
This page compares DeepSeek V4 Pro (DeepSeek) and Qwen: Qwen3 14B (Alibaba) using the latest snapshots we have as of Aug 17, 2026. Qwen: Qwen3 14B wins on output price at $0.24/1M. DeepSeek V4 Pro has the larger context window (1M tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.

Top DeepSeek vs top Anthropic Elo. Usually V4 Pro vs Opus 5. License and invoice decide as much as Elo.
2026-06 open-weight-adjacent flagship. The usual cheap-vs-Claude question starts here.
Jan 2025 reasoning model. Still searched. V4 Pro is the newer DeepSeek buy.
