Pairwise benchmark snapshot · Aug 16, 2026
This page compares DeepSeek V4 Pro (DeepSeek) and GPT-4o (OpenAI) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, DeepSeek V4 Pro is ahead by 201 points (1,536 vs 1,335; seed-bootstrap (Aug 1, 2026)). On SWE-bench coding, DeepSeek V4 Pro resolves 71.6% versus 54.8% (seed-bootstrap (Aug 1, 2026)). GPT-4o streams faster (110 tok/s) while DeepSeek V4 Pro is the cheaper output token ($0.87/1M). 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.
Deprecated for buying. Kept because “4o vs sonnet” is still a typed query.
