In late July 2026, DeepSeek released the public beta of its DeepSeek-V4-Flash API. The V4-Flash-0731 model featured re-post-training designed to drive higher agent-oriented benchmark scores, achieving high rankings on Terminal Bench 2.1 and Frontend Code Arena. Priced at $0.14 per million input tokens and $0.28 per million output tokens, the model was roughly one-third the cost of the V4-Pro offering.

The low pricing and high performance-to-cost ratio led to a massive surge in demand. The V4-Flash model was reportedly the fastest-growing model ever measured in terms of token usage on the Ollama platform. This influx overwhelmed DeepSeek’s hardware capacity, which relies on approximately 20,000 Nvidia H100 GPUs, resulting in slower response times.

In response to these capacity constraints, DeepSeek announced forthcoming substantial price increases for all API services. Analysts suggest the hike may function as a traffic regulation tool to manage extreme service loads. While third-party providers like DeepInfra and OpenRouter can host the open-weight version at potentially lower rates, developers have noted that official APIs often provide better efficiency, such as higher cache hit rates.

To support future models like V4 Pro, DeepSeek disclosed plans for a new data centre in Inner Mongolia, targeting roughly 1 GW of AI processing power. The announced price hike will affect users of the hosted API, while the open-source version remains unchanged.

## Timeline
