Deepseek ships improved V4 Pro, open-sources its agent software, and raises API prices
Deepseek released its V4-Pro model and open-sourced Harness v0.1 agent software under the MIT license. Concurrently, the company increased API pricing, with cache hit costs rising sixfold.
Deepseek has transitioned its V4-Pro model from testing to general availability. Alongside this release, the company published Harness v0.1, an agent framework, under the permissive MIT license.
The launch coincides with a significant adjustment to API costs. Specifically, pricing for cache hits has increased by a factor of six, affecting workflows that rely heavily on repeated context retrieval.
Open-sourcing the agent software aligns with Deepseek's strategy of fostering ecosystem development while maintaining control over core model inference. The price hike suggests a shift toward monetizing high-volume usage more aggressively.
This move positions Deepseek competitively within the open-weight model landscape, balancing accessibility through licensing with revenue generation via API services.
