DeepSeek said it will raise API prices for its V4 Flash and Pro models while Flash remains in public beta.

The reported new structure charges lower off-peak rates and higher peak rates; the source says Flash price changes range from 57% to 371%, while cache-hit pricing can rise by as much as 1,100%. Separately, Composio reported that Flash passed 129 of 240 runs across eight agent harnesses on 30 multi-step tasks, with results varying by harness and configuration.

The source says there is not yet an evidence trail of settled enterprise deployments or named customers.
