On August 13, QbitAI reported that DeepSeek has released the official version of V4 Pro, the latest step in the company's flagship model line.

According to the report, developers can now call V4 Pro and get the complete model directly — the full-capability official version is fully open through the API, with no staged rollout or gated preview required.

Based on the report's framing, V4 Pro is positioned against Fable 5 on multiple capabilities, signaling an attempt to compete head-on with the current flagship leader rather than delivering a modest generational update.

The release matters because DeepSeek has built its reputation on strong cost-performance and an open model ecosystem; the official V4 Pro brings the company's strongest capabilities to developers in complete form for the first time.

For developers, V4 Pro means the full-strength model is now the default option when calling DeepSeek, replacing limited preview tiers or lighter versions, which makes integration costs and migration paths much clearer.

What to watch next: complete benchmark results from DeepSeek, detailed specifications and pricing, and whether real-world performance under production workloads matches the positioning.

Taken together, the official V4 Pro moves the DeepSeek-versus-Fable 5 contest from announcement to substance, adding a serious contender to the flagship model race.

Why it matters

With V4 Pro fully available through the API, DeepSeek's flagship capability has reached a directly consumable stage, intensifying head-to-head competition with top-tier models like Fable 5.
