About

DeepSeek's open-weight models deliver frontier-class reasoning at a fraction of typical cost, making them a favorite for high-volume agent workloads.

On Brainbase, DeepSeek V4 Pro runs platform-billed via Baseten inside Codex Agent, OpenCode, or Qwen Code.

Available on Brainbase:

  • DeepSeek V4: DeepSeek's open-weight reasoning flagship, including DeepSeek V4 Pro

Run these models in Codex, OpenCode, or Qwen Code — selected per task like any other platform model.
