2 providers serve this model
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.
| Provider | Upstream model id | In / 1M | Out / 1M | Billing | Uptime |
|---|---|---|---|---|---|
| Together AICheapest | openai/gpt-oss-20b | $0.0500 | $0.2000 | Credit | |
| Groq | openai/gpt-oss-20b | $0.0750 | $0.3000 | Credit |
What the uptime column is, and is not
It is availability of the provider, not of GPT-OSS 20B in particular: reachability probes we ran, and the success rate of requests we routed to that provider across the whole catalogue. Time to first token and throughput are still absent, because Multigrid has not served enough traffic through this model to publish honest ones. Nothing here is estimated: prices, context window and capabilities come from the provider’s own documentation, and the ribbon comes from rows we wrote.Call it
Same request shape as every other model in the catalogue.

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?
