$113MSeries B
A $113M Series B for an LLM router signals that the multi-model abstraction layer is now table stakes—not a nice-to-have. CapitalG's bet suggests the real value isn't in picking winners between Claude/GPT/Llama, but in letting developers switch seamlessly as pricing and performance shift. If you're building any AI product that touches multiple model providers, this validates that your customers will demand portability; if you're building *for* developers, watch how OpenRouter uses this capital to lock in distribution before the model providers build this in-house.
