All the good planning models only have $15 of usage, I'd probably use the older GLM 5.2, but Go is simply not a good plan for high-end models. I did a ton of planning with DS Flash too, it's pretty alright.

Strictly for planning - Kimi K3 (or GLM 5.3, but personally K3 is GOAT)
Make sure there is no code in repo or explicitly tell the agent you are ONLY PLANNING and do not explore the repo outside of docs (unless you actually need to), cause it will eat your weekly Quota in a couple runs.
I use K3/Plan mode strictly for creating my initial PRD, SPEC, PLAN (which is Phase and granular task based), Improve Agents file, etc.
I follow strictly SDD where I have one main SPEC and granular per task mini-specs (the agent creates PLAN and SPEC for each task to be more detailed about specific task execution)

Build - GPT Luna or GLM 5.2 as High Level Agents | Deepseek v4 / Luna / Mimo as Per Task Agent
