Cost optimization
Tuned cache strategy keeps cache rates above 98%; cache hits are billed at only one-tenth of official input pricing.
AI Make Your Work Easier
E2 API turns rough ideas into code, documents, agents, workflows, and product experiments through one OpenAI-compatible entry point with stable forwarding and cost observability.
