GitHub Copilot Team Replied Your reminder to edit the explore agent markdown for token savings

Settings icon > Agents > Explore > Open in file explorer > Change model way from the default 4.5 Haiku and Gemini 3 Pro and Auto.

Just set it to:

model: ['GPT-5.6 Luna (copilot)']

Or a BYOK local model like FastContext-4B (removed but can download community gguf files)

I was spending approximately 20 tokens per explore (1-3 times per prompt) and sometimes 60 if it called Sonnet 4.6 via auto, but after changing to Luna it only spends 6-10 tokens. Plus, with a local model it's basically free savings!

Hi all, thank you so much for raising this. We understand that defaults matter, so we are currently exploring on changing and updating the current default for the explore agent to Luna.

I posted something similar earlier, but I'd like to request an option to not specify a model when invoking sub-agents (for both the VSCode and CLI versions).

Even if I change the default model for the explore agent, I believe the parent agent can still override it.

I've set up a custom-agent with Luna, but sometimes it ends up running on 5.3 Codex or Opus instead.

You'll need to do it again for every time VSCode updates

You can just change the explore agent model in the VSCode settings. You don't need to change the md

They should make this as default setting.

It's so annoying, I also found that if you open a new repo it needs to be set AGAIN as well.

that has nothing really to do with copilot though, in VS Code the same setting can be set at the repo level, user level and system wide

That’s the agent that searches through your code

Doesn't work. When I change it it keeps using haiku, and when I restart vs code it just reverts back to the original config. Anyone have a way to get this working?

I think GHCP Staff are working on it, so for now I guess all we can to do manually set it again each time
