⚡️Snowglobe: Simulations for your AI
Sep 25, 2025 · 26:14
Shreya Rajpal returns to Latent Space to launch Snowglobe, a simulation engine that lets developers test AI products by generating diverse simulated user interactions before production, inspired by self-driving car simulation where Waymo logged 20 billion simulated miles versus 20 million real miles. She explains how simulation uncovers failures like over-refusal—a problem that emerged for a design partner who initially worried about toxicity—by generating personas with varied styles and goals. Snowglobe uses a multi-model architecture (proprietary and open source) to create realistic, diverse conversations, and it supports testing across chat, voice, and tool-calling agents. Pricing is usage-based per message, with persona modeling included. Shreya highlights enterprise use cases, such as comparing vendors or generating training data for fine-tuning, and notes the company is hiring a product designer, product engineer, and research staff.
