Rumor: DeepSeek V4 Imminent, Rivals Opus 4.6 at Lower Price

teortaxesTex · x · 2026-07-18

Rumors suggest DeepSeek V4 is about to transition from preview to official release. According to the cited leaks, V4 Pro scores 80.6% on SWE-bench, closely trailing Opus 4.6 at 80.8%, while costing only $3.48/M for output—a seventh of the latter's price—and supporting a 1M context window. However, the original poster expresses strong skepticism about the leak's authenticity, pointing out that the cited price is actually from April's V4 preview, and Opus 4.6 is also a six-month-old model, suggesting the data has been cobbled together and is misleading.
