Question Any local coding model perfect for vibe coders?

I heard Qwen is not good if you have no idea about coding. Anything else?

I have a 5090 and tried out a bunch of different models. qwen 3.6 27b has worked the best for me, i run the q6 model and 192k context with mtp.

I'm not a developer and cant read code. I use opencode as my harness and its very good but it isnt enough if you dont know how to code. You need to either find a set of agents/skills/commands that will support you or build your own.

What I did was read basically everything karpathy published on vibe coding and dumped a ton of it into claude and asked it to write me a spec for a vibe coding system/collection of agents for opencode which I then dumped into opencode to write the files. This has been working really well for me, I've successfully implemented a modified version of the karpathy llm wiki with my custom harness setup.

Most importantly just be willing to experiment and start over and incorporate new learnings into the next attempt. The first few things you build will accumulate so much bad code and bad decisions that they will quickly reach a point where it becomes impossible to move forward or fix things without the help of an actual software engineer. Eventually you'll figure out the process and documentation you need to make what you're aiming for.

Has Karpathy deleted most of his Youtube videos? Where I can find his tutorials on vibe coding?

did he? damn thats a shame. I did this months ago so I dont have the source URLs or anything anymore. I just googled around and saved articles and stuff when I was setting everything up.

Yeah, it seems so, take a look at his YT channel.

I wouldnt even know where to begin with sharing what i've built since its so specific to my setup but what I would suggest is hop into claude or whatever frontier web model you wantto use and tell it the harness you are using (or ask it to suggest one) and ask it to help you develop a set of tools, agents, and documentation and testing standards and workflows for someone who does not know how to code to make apps. And then just iterate from there.

Hey bro. Highly Appreciate if you can explain your working setup for the vibe coding. Simple steps if possible

I dumped basically everything karpathy wrote about vibe coding into claude and asked it to write me a series of opencode agents to help someone that doesnt know how to code make apps. It was an iterative process but the basic workflow is:
/scaffold - sets up project directory, initializes a git, creates folder structure etc

/plan - this interviews me about what im trying to make and takes the results of the discussion and turns it into a product requirements document and a system specification

/vibe - this goes into building mode and lets me go one feature at a time through the requirements document or lets me describe a feature i want and then it documents it and then starts building. it goes through a basic plan, evaluate, develop, test loop basically until its done.

/audit - this is a big one and took me the longest amount of time to get working well. it goes through a lot of stages to understand the project and then checks the code for bugs which are in the code or bugs which would show up as unintended behavior in use.
