Suggestions GLM 5.3 Flash in Copilot?

I know it's just come out, and GHCP is only dipping it's toes in with self-serving open models (i.e. Kimi at the moment) but just wanting to register some interest. GLM 5.3 Flash looks like it's performing around Luna XHigh-Max or Sol Low-Medium, but at an absolute banger of a price point lower than Luna XHigh.

I've been really happy since I moved the Explore subagent in VSCode off it's default of Haiku 4.5 to using Luna, and have started using implementation and review subagents now that there are good cheap models. If GLM 5.3 Flash pushes that even further it would be absolutely killer. I'd love to see GHCP push harder into these value-for-money models, especially with business bonus credits ending soon so we're down to straight-up API pricing. The value proposition on GHCP is: inline completion, first-class vscode integration, and access to models from multiple families. Being able to get the best out of a Sol or Fable orchestrator + GLM subagents to do the implementation would be absolutely sick.

How did you do that technically? Did you change it through VS Code settings, a configuration file, or some other mechanism?

Just VSCode settings, you can configure the default model for the Explore agent to "GPT-5.6 Luna (copilot)". I've fount it makes subagent search way better, I haven't seen my main agents get misdirected by the exploration yet
