   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.

   Coral AI Labs and academic collaborators introduce AgentRadio for asynchronous coordination among coding agents

   Researchers from Coral AI Labs and several universities presented AgentRadio, an asynchronous message-passing layer that lets multiple coding agents communicate during execution without pausing their primary work. In tests on the SWE-Atlas QnA benchmark, a four-agent setup using AgentRadio improved long-horizon codebase question accuracy over single-agent baselines and outperformed a single Claude Code agent running Claude Opus 4.8. The team also said the ideas are being adapted into a commercial product called Coral Code.
