I have same the same FOMO to use SOTA model for all planning and brainstorming session. However, I’m unsure how do you bring deepseek for subagent task. Could you describe your workflow?
For myself, using Codex, I always have to explicitly tell codex to use Luna with high reasoning for smaller, bit size tasks.
I'm using OMP (oh-my-pi) and the minimum you need to do is just set the @task role to Deepseek:max.
Subagents can spawn with other profiles e.g. scout (uses @smol) and reviewer (@slow). You can set SOTA with higher thinking for @slow and Deepseek with lower thinking for @smol or something even faster/cheaper.
There's also weirdly named /vibe mode that gives explicit instructions to the main model to act as an orchestrator but I find this unnecessary if your main is SOTA, they are already super eager to spawn subagents by default.
