Could you say more about how caching works? One major advantage of sticking with a single model is saving money on cached input tokens. I'd imagine if you swap between a bunch of models, you may improve performance but cost would would balloon out of control
The trick is to rarely switch, or switch at task boundaries. Often the conclusion of routing is actually "this one model is actually at the pareto front for this task, just use it always".
That is another way to do. Or we can automatically figure out which models the subagents should be using for you. And update them as new models come out and the work your subagents do changes. More than one way to skin a cat.
Open source and no markup is the right default for a gateway. The caching question above is the one I would want answered before swapping models though.
Amazing! Really brilliant idea, thank you for sharing this project. There is so much ground to cover in the LLM gateway / routing / reporting world, and this is a great start. The Tinker implementation is my favorite part, fine tuning is much better than a sea of context files.

But then it's better to just not have a gateway switch models at all.
Just have the harness able to choose which model its sub-agents use, then tell it how to split up tasks and which models to use when doing so.

and caching is related to performance too ofc
Very cool. Does your gateway decide effort levels as well? Or just models?
Yep! One interesting example is often Opus 5 on low reasoning ~= Opus 5 on high reasoning.

Ans: we rarely switch, often times it's just a "switch to using this model for your agent"

Thanks! We are going to add continual RL via Tinker soon too
I have not tried it yet. Is it similar to LiteLLM? If so, what sets it apart?
Router and model optimization from traffic is the main differentiator
Also a hosted marketplace, not just BYOK
You started it a week ago? I look forward to checking back in 3 weeks when you've exited for $1B
See you soon
Super interesting and congrats on the release. Curious if you initially had this in Python and then rewrote in Rust?
Yep! If you look at the commit history that's exactly what happened.
Finally an open source tool doing this!
