Day 1 of my multi-LLM experiment: testing AgentRouter + GLM-5.3

I’m starting a small experiment around multi-model AI development.

Instead of assuming one LLM is best for everything, I want to test several models against the same real-world tasks and track the results.

The first platform I’m testing is AgentRouter.

It caught my attention because I can experiment with multiple models through one platform, and GLM-5.3 is currently available.

There’s also a $150 credit offer for new users, which makes it easier to run some experiments before committing more money.

I’m going to track:

📌 Coding performance
📌 Agent/task performance
📌 Response quality
📌 Speed
📌 Cost
📌 Overall developer experience

I’ll share the results as I go.

For anyone who wants to test it alongside me:
