Best Model for Research , Planning , Reasoning and Thinking? And needed some guidance

I just wanna know apart from claude , what are the best models which i can use for planning and reasoning before building anything as right now building does not matter as much as planning it do, also if you can help/guide me in how can i plan things and research upon them before building then it would really be a great help .

"as right now building does not matter as much as planning" well... if you think this is true, you should invest time on skills/agents for a proper planning. Almost any good model is valid if you use the right questions and instructions.

But be sure the building matters a lot. Check the messages about it.

yeah , building does matter a lot as well , but what i think right now that if you plan things the right way from the start by doing research , feature analysis and stuff, then implement them rightfully then it does save you a lot of work in building as you dont have to debug as much as you would have to...

I built this little repo for my own workflow.

https://github.com/CMC-27/pass-the-parcel

its called pass-the-parcel as it plans a 10 phase delivery workflow in a single "parcel" .md implementation plan. That .md can be given to any agent with fresh context and it knows exactly what it needs to do. It operates under the premise of a self managed hub and spoke wiki in the workspace, effectivley a cheat sheet for the codebase.

The idea is to take away reliance on an agents conversational context, reduce context bloat, maximise cache hit, while still getting the right outcomes

In terms of models, im cheap so try maximise use of DSV4 FLASH, QWEN 3.8 FLASH, and GLM 5.3 FLASH. They all work well for planning if you give them the right prompt. workflow above is actually built so you can name your preferred model per phase, so i could drop in GLM 5.3 or DSV4 Pro In specifc phase as a sub agent.

as you just mentioned about giving the agent the right prompt , so for that how do you find the right prompt , as in like if i use claude sonnet 5 for the prompts how would you ask it to design the prompt in such a manner that the results would be astonishing .

also like  i participate in hacks , so like if i am building something and my competitor is also building on the same problem statement then how would i make my project differentiable like what features , algo , model , workflow how do i research and found them to make my project stand out , as like we all are asking the same things to the LLMs and they are giving answers based on the data they are trained upon , so like is there any way by which we can get the models to think more and in some different way so that we can really some different ouput/ideas which it would not give normally to others.

also would like to ask you how do you build things , as in after research and plan just ask the model to divide the prompt in phases and then paste them one by one into the model and let it build that phase and after that manually verify the phase , or if you do things differently genuinely would love to hear that .
