DeepSeek Launches V4 API with 1 Million Token Context

DeepSeek launched V4-Pro and V4-Flash APIs with native support for up to 1 million tokens.

The new release adds document processing and workflow integration features for developers.

DeepSeek also published model weights and documentation to support adoption.

Older APIs are scheduled to shut down on July 24, 2026, so teams will need to plan migration.
