I have had the chance to test the main Chinese models through OpenRouter but the Pay-as-you-go model is expensive compared to a subscription model, but I don't want to marry to a single provider.
Thanks for bringing OpenCode Go to my attention. Your comparison is the research I didn't know I needed, and I will be cancelling my Copilot subscription to replace it with OpenCode Go right away.
opencode go gives about 14x the requests of copilot pro. I was like, there must be something not right.
Then I compared the best model GLM5.1 on opencode go, and antropic opus 4.6, yes opus is better on most benchmarks, but glm 5.1 is not too far behind.
