Caper Data Flywheel and Observability

2026

Instacart built Capsight, an end-to-end platform for Caper smart carts. It acts as a distributed data collection and model improvement engine. The system comprises the Capsight Collector (on-device intelligent data capture), Capsight Depot (cloud platform for data management, ingestion, curation, and AI-assisted annotation), and Capsight Learner (distributed training platform). This enables a continuous feedback loop from edge-captured data to ML training, significantly reducing model iteration cycles and improving accuracy by systematically gathering diverse, real-world data. Future work includes expanding to full sensor fusion and developing a foundation model for understanding store environments.

Turning Data into Velocity: Caper’s Edge and Cloud Data Flywheel with Capsight

2/18/2026

This post introduces Capsight, a new platform for Caper smart carts. It addresses challenges in scalable on-board observability, data quality/diversity, and end-to-end model cycle time. Key components include the Capsight Collector for intelligent, trigger-based, and optimized on-device data capture; Capsight Depot for processing, indexing, search, visualization, and AI-assisted annotation (reducing annotation costs by over 70% using VLMs); and Capsight Learner for automated model training and evaluation (reducing training time from one week to two days). The system has already shown over 5% accuracy gains and reduced the overall iteration cycle from a month to a week.
