Three key points

  1. NVIDIA released Bolt E4B on October 23 for local conversations and tool calls.
  2. In its Reachy Mini demonstration, Bolt handles speech and animation scripts while a separate Cosmos model handles vision.
  3. The roughly 4GB figure concerns target model workloads, not total robot-system memory or general autonomous-task performance.
