What is DeepSeek V4-Pro best for?
DeepSeek V4-Pro is best for frontier-level coding and reasoning on a budget. It is a strong fit when that workflow matters more than the tradeoffs around budget pricing and balanced speed.
Best open-weights flagship — near-frontier coding at a tenth of the price.
Frontier-level coding and reasoning on a budget
You need vision input, verified agentic performance, or predictable pricing (surge pricing and an announced increase loom).
Open-weight preview April 24; GA ~July 20, 2026. Off-peak pricing verified on api-docs.deepseek.com; Beijing-business-hours surge doubles it. Legacy deepseek-chat/reasoner endpoints retired July 24, 2026.
80.6% SWE-bench Verified (self-reported) — reported as tied with Gemini 3.1 Pro
93.5% LiveCodeBench and Codeforces 3206 — elite competitive-coding results
1M context with 384K max output at $0.87/1M output — an order of magnitude cheaper than closed frontier models
Independent harnesses report much lower agentic scores than the self-reported numbers; trails GPT-5.6 and Opus-class on hard agentic evals
Peak-hour surge pricing doubles rates, a price increase is announced, and it's text-only (no vision)
