Developer finds LLM planner adds no value to app generation tool

A developer has created a tool called appgen that generates a running Python application from a single sentence, without using a language model for the core application generation. The accompanying planner, which uses a local LLM (qwen3-coder:30b), was tested to see if it provided any benefit. In tests using the florinpop17/app-ideas dataset, removing the LLM planner did not negatively impact the success rate of generating applications, suggesting the planner's contribution was negligible.
