What happened
AI gateway provider OpenRouter has raised a $113 million Series B led by CapitalG. According to a report from The New York Times, the deal values the company at approximately $1.3 billion post-money — more than double its valuation from a year ago.
The company claims to process 100 trillion tokens per month, a five-fold increase from six months ago. Its gateway provides access to over 400 different models from providers like OpenAI, Anthropic, and Google.
How the room's reading it
The funding is widely seen as strong validation for a multi-model future. The consensus framing, captured by outlets like TechCrunch, is that enterprises are actively avoiding vendor lock-in with a single model provider. Instead of standardising on one model, builders are treating them as swappable engines, choosing the best tool for a specific job to optimise for cost, speed, or accuracy.
OpenRouter’s growth suggests this isn't a niche strategy anymore. It's becoming the default approach for shipping complex AI applications, where no single model excels at every task.
Sailfish's take
We're not surprised by the valuation. The multi-model world isn't coming — it's been the reality for serious builders for the last year. The real story isn't just about swapping models, it's about the intelligence layer you build on top. Abstracting the model provider is the first step. The next is building smart, dynamic routing based on cost, latency, and task complexity.
This is where the value is moving. We've shipped enough products to know that the model itself is just one piece of the puzzle. If you're still hard-coding calls to a single foundation model, this is the week to stop. The work now is in the routing layer.
