Ramp launches its own AI model router, called Router

The US-only API service is free through the rest of 2026 (plus a $26 credit), routing across models from OpenAI, Anthropic, DeepSeek, Moonshot, Minimax, Nvidia, xAI and Z.ai. Optional strategies let users route by benchmark, flex tiers, or difficulty, and Ramp says it has used the router internally for three years.
