Limitations of Bud Coder
Currently, Bud Coder is in its early stages, with basic processes completed but optimization of the intelligent system not yet started. Due to the limitations of the GPT-4O model, there are certain restrictions:
<ul>
<li>Suitable for automatically handling simple logic and writing moderately complex plugins under human interaction. High complexity tasks cannot be completed yet.</li>
<li>Can only modify specified single files, not the entire plugin directory.</li>
<li>Due to GPT4O’s maximum context of 128K, considering output return, the maximum code submission length should be within 40-50K tokens.</li>
</ul>
