DeepSeek V4-Pro holds $0.87 pricing as SWE-bench Verified climbs to 80.6%

DeepSeek's V4-Pro production release is a pricing-discipline story as much as a capability one. The model (internally versioned 0813) exited preview after months of testing, and the notable move is that DeepSeek held the output price flat at $0.87 per million tokens even as SWE-bench Verified improved to 80.6% — meaning customers get a materially stronger coding model at the same cost per token. A companion V4-Flash release accompanied the launch, targeting latency-sensitive and cost-sensitive workloads.

The competitive positioning is explicit: DeepSeek is aiming V4-Pro squarely at Claude Opus 5 and Gemini 3.1, betting that an 80.6% SWE-bench score at sub-$1 pricing undercuts frontier labs on the price-performance frontier that matters most for agentic coding at scale. This slots into the week's open-weight-and-cheap theme alongside Qwen3.8-Max, reinforcing the narrative that Chinese labs are competing primarily on cost discipline.

The skeptical angle surfaced on r/DeepSeek, where users debated why anyone still chooses DeepSeek after prior price increases — a reminder that its cost advantage has narrowed over time and that raw benchmark scores don't capture reliability, tool-use quality, or long-context behavior in production. The reported 160,000-chip Huawei cluster suggests DeepSeek intends to keep scaling; whether it can hold the $0.87 line as it invests in that infrastructure is the tension worth tracking. For now, holding price flat while raising a headline coding benchmark is exactly the kind of move that keeps DeepSeek in enterprise evaluations.
