О компании и продукте

• White Circle https://whitecircle.ai is an AI Safety company building the safety, reliability, and optimization layer for AI systems.

We automatically test, enforce, and continuously improve these policies at scale.

• We process over one hundred million API calls every month
• We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model
