   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.

   Nvidia releases Nemotron 3.5 Lightning and open-source NeMo Switchyard for agent routing

   Nvidia has introduced Nemotron 3.5 Lightning, a 30 billion-parameter open mixture-of-experts model aimed at high-volume agent workloads, alongside NeMo Switchyard, an open-source library that routes steps in an agent workflow across different models. Nvidia says Lightning delivers faster output than comparable models and that, when paired with Switchyard, the setup can maintain strong task performance while reducing benchmark costs versus relying on a frontier model alone.
