Has anyone had any luck with building with an LLM?

Questions

I have a flow I am attempting to build with the help of chatGPT and Grok and its not doing well. Has anyone found any LLM that works well?

I think you are asking which LLMs can help with building workflows(?)

I mainly use Gemini 2.5 Pro and notice the following:

Workflows

  • It’s moderately helpful constructing a workflow. As a workflow complexity increases, the reliability decreases.
  • It will occasionally suggest deprecated nodes.
  • Very good at combining a few nodes to accomplish sub-tasks within a workflow.

Nodes

  • Very helpful when I’m trying to figure out what parameters to use, how to set them and explaining what they do.
  • Very helpful constructing expressions.

DeepSeek:
I used this for a while when it first came out. It was much better at helping with N8N than other LLMs but, in my experience, Gemini 2.5 is far better.

An important consideration:
Context is everything. The more details you give an LLM, the more likely you will get helpful advice. If I’m asking an LLM for help, I’m very precise about what I’m trying to accomplish, what I do not want and what I expect the LLM to provide.
An LLM’s “memory” is limited which means that as you continue to give it prompts, older input (and context) is eventually replaced with the newer prompts. I will construct a paragraph or so of context, save it in my text editor and feed it back to the LLM when I start to notice the accuracy of the advice falling off. This will happen with any LLM.

That’s my two cents. :slightly_smiling_face:

Thank you. I really appreciate your post After many hours of yelling at chatGPT and Grok, I finally realized my problem is 100% due to the latest n8n upgrade I did. I am self hosted. I want to open a json with 200 records. I found I can do it in the older version and it can’t access the same file in the new. Here is an example path: /home/oceanviewmedia/ssbdata/3401Main/process_files/World of Amazing Animals/mainGroup.json — do you happen to know a way around this issue ? I’m told the newer version is much more strict.

I just realized I would not have this issue if I used Airtable to store my records! Correct?

Hi there.
It sounds like you are making progress. It’s really frustrating when you’ve been staring at a problem for hours (or days) and you get nowhere.

I can’t help with your last bit. I don’t know enough about self-hosting and I’m not familiar with the issue you described.
That said, could it be a memory issue? I read somewhere that when you self-host you can control the amount of memory you want to provide.

I’m surprised you haven’t received any other input on this. People are generally happy to help. Definitely search the forum for similar issues, yours strikes me as fairly common and if you don’t get anymore help, I would close this question and rewrite a new one. New questions tend to attract more help. Be sure to mention that you are self-hosting, I think it’s probably related.

Sorry I can’t help further with this. :confused:

Best :slightly_smiling_face:

No probelmo my friend, I’m new to the community and it was my first question. BTW, I got the entire process working using Airtable. May I ask were you are from? Do you offer automations as a service?
