What stands out

What its maker marketed at launch, and what people found later, each with its source.

  • Embodied reasoning in the public Gemini API

    ER 1.5 (2025-09-25) exposed embodied reasoning (pointing, 2D boxes, trajectories, task planning, tool calls) available in the public Gemini API, while the VLA stayed partner-only.

  • Instrument reading (ER 1.6)

    Reads pressure gauges, thermometers, sight glasses and digital readouts: 86% (93% with agentic vision) vs 23% for ER 1.5 and 67% for Gemini 3 Flash; built with Boston Dynamics and used by Spot for inspections.
