If you’re working with multiple AI models, this is a nice quality-of-life upgrade.
The Open Router now supports 58 different models, including Claude Opus 4.5, making it easier than ever to route requests without constantly thinking about which model to pick.
What’s new (and actually helpful):
- Tool calling now works
Open Router can handle tool-calling requests, which means smoother agent workflows and fewer hacks to make things work. - You get more control
You can now customize routing preferences instead of accepting a one-size-fits-all setup. Faster, cheaper, or model-specific — it’s up to you. - No hidden costs
Nothing changes on pricing. There’s still no markup beyond the model’s normal market rate.
The real win here isn’t just the number of models. It’s the fact that Open Router keeps things simple while AI stacks get more complex. You get flexibility without micromanaging, and power without surprises on your bill.
As more teams move to multi-model setups by default, updates like this quietly remove friction — and that’s often where the biggest productivity gains come from.
