Multigrid picks between them on every request using your policy. Each price is what that route costs us, and we add no spread of our own to it.

No performance data published yet
Time to first token, throughput and uptime are measurements, and Multigrid has not served enough traffic through GPT-OSS 20B to publish honest ones. When it has, they will appear here per provider, taken from real requests. Nothing on this page is estimated: prices, context window and capabilities all come from the provider’s own documentation.Call it

Signing up takes no card and commits you to nothing — you start at a zero balance, so nothing can be charged until you decide to add credit. The playground opens on GPT-OSS 20B and prices every answer as it arrives, at the rate shown above — what the route costs us, with nothing of ours added. Already have an account?
