FAQ 9

What is Snowglobe?
Snowglobe is a simulation environment for LLM teams designed to test how their AI applications respond to real-world user behavior. It enables users to run full workflows through realistic scenarios, catch edge cases early, and confidently improve model performance before deploying to production. Snowglobe helps AI teams test LLM apps at scale by simulating real-world conversations, uncovering risks, and improving overall model performance.
How to use Snowglobe?
To use Snowglobe, users connect their conversational AI agent via API or SDK. The process involves configuring simulations with realistic personas and scenarios, running hundreds of conversations, exploring the results, and analyzing failure patterns and performance metrics. This allows for generating judge-labeled datasets for evaluation and fine-tuning.
What is chatbot conversation simulation?
It’s the practice of simulating real user conversations with your chatbot to create data at scale. Snowglobe generates those conversations and labels outcomes so you can evaluate and train reliably.
How does Snowglobe help with chatbot evaluation and testing?
Snowglobe helps by simulating real-world conversations, uncovering risks, and improving model performance before launch. It generates judge-labeled test datasets and surfaces issues early that manual testing misses.
Can Snowglobe generate training data for fine-tuning?
Yes, it generates high-signal training data from the same runs, including judge labels, preference pairs for DPO or reward models, and critique-and-revise triples for SFT.
Will this help reduce hallucinations and improve RAG reliability?
Yes, Snowglobe simulates conversations to test for AI risks such as hallucination and toxicity, helping identify previously overlooked or undertested cases, which in turn aids in reducing hallucinations and improving RAG reliability.
How fast is it and how much coverage do I get?
It can run hundreds of conversations in minutes across varied intents, personas, tones, goals, and adversarial tactics, providing comprehensive coverage that manual testing misses.
How do I connect my chatbot and stack?
You can connect your conversational AI agent by bringing your API or easily integrating using Snowglobe's SDK with minimal effort.
How is Snowglobe priced?
Snowglobe offers a Self-service plan which is free for the first 250 messages per month, then $0.25 per generated message. There is also an Enterprise plan with custom pricing.
