SMRTR summary

Tesla demonstrated a gold-colored "version 2.5" Optimus robot that slowly walked and responded to voice commands with Grok integration, but showed limited real-world capabilities. CEO Elon Musk clarified this wasn't the upcoming "sublime" V3 model, noting the current version remains cautious about space and movement. The robot features smoother external design with tighter seams and a more human-like silhouette, representing incremental progress toward Tesla's goal of production by 2026.
