how does this compare to bifrost - another golang router?

First of all, GoModel doesn't have a separate private repository behind a paywall/license.

It's more lightweight and simpler. The Bifrost docker image looks 4x larger, at least for now.

IMO GoModel is more convenient for debugging and for seeing how your request flows through different layers of AI Gateways in the Audit Logs.

That would be valuable if there's a commitment to never have a non-opensource offering under GoModel? If so, you can document it in the repo.

I would love to keep it open source forever, but I can't promise that for now. I've written a whole doc page about it if you're curious: https://gomodel.enterpilot.io/docs/about/license

If your concern is someone selling GoModel as a service, you could add a license provision for that. Technically it'd no longer be open source, I think, but most people won't care.

I'll consider it for sure.
