What it is
VCRouter
VCRouter is the model router Vela is releasing alongside VC Arena. One API call sends any venture task to whichever model currently leads that task in the arena.
As the leaderboard moves, the routing moves with it. The design follows directly from Vela's arena data, where the blend of models outperformed every individual model.
How it works
In four parts
- I
Ask
One API call with any venture task: sourcing a thesis, forecasting a seed-to-Series-A conversion, drafting a market map.
- II
Route
The task goes to whichever model currently leads it in the arena, where forecasts are scored against what actually happens.
- III
Keep up
When the leaderboard moves, the routing moves with it, so the answer comes from the best model this week rather than last quarter's.
- IV
Blend
Averaging beats champion-picking: on Vela's arena sample the average of all models beat every individual model at ranking outcomes, so VCRouter blends as well as routes.
