DeepSeek raises prices for V4 Flash and Pro as third-party tests show weaker real-world agent reliability

DeepSeek has raised prices for its V4 Flash and V4 Pro models, extending a recent shift away from the ultra-low pricing that helped drive developer adoption. VentureBeat also cites Composio testing in which V4 Flash completed 129 of 240 difficult agent-task runs across eight harnesses, suggesting leaderboard strength did not fully translate into consistent real-world automation performance.
