AI output and automated actions can be inaccurate, biased, incomplete, unsafe, stale, or misleading, while services may process confidential, copyrighted, personal, location, health, financial, or regulated information. Check consent, retention, model-training, licenses, platform rules, renewal terms, accessibility, and security, and use qualified human review for high-impact work.

  • Standard Python library modules were supported
  • NumPy enabled numerical calculations in compatible sessions
  • Matplotlib output could be rendered as plots
  • Standard output appeared alongside the conversation workflow
  • Users could upload files for analysis by local Python code
  • Generated files could be downloaded when the exact filename was supplied
  • Micropip enabled installation of some additional Python packages

Cons

  • The last recorded extension update was December 2023
  • ChatGPT interface changes can break an extension that modifies the page
  • The original Chrome Web Store URL may not resolve in every region
  • An infinite loop can freeze the extension
  • Interactive input calls are explicitly unsupported
  • Edits made to a code block do not persist
  • The package selection is narrower than a full local Python environment
  • Some packages cannot run within Pyodide or WebAssembly
  • Large files and calculations are constrained by browser memory
  • Browser execution can be slower than native Python
  • Uploaded files remain sensitive even when computation is local
  • Prompts and generated code are still visible to OpenAI through ChatGPT
