Remove unused import openai from recursive-thinking-ai.py

[manato-tajiri]

Problem

recursive-thinking-ai.py imports openai on line 1, but this package is missing from requirements.txt, causing a ModuleNotFoundError when following the standard installation procedure.

See issue #2.

Analysis

The import openai is dead code — the script uses requests to call OpenRouter's API directly and never calls any function from the openai package.

Fix

Removed import openai from line 1 of recursive-thinking-ai.py.

This is the cleaner fix compared to adding openai to requirements.txt because:

• The package is not actually used by the code
• It avoids adding ~6MB of unnecessary dependencies
• No changes to requirements.txt are needed

Verification

• python -c py_compile confirms syntax is valid
• No references to openai remain in any project files
• Running uv pip install -r requirements.txt && python recursive-thinking-ai.py no longer produces ModuleNotFoundError

Closes #2

@PhialsBasement This PR fixes the ModuleNotFoundError: No module named 'openai' issue. The fix is a one-line deletion — remove the unused import openai from recursive-thinking-ai.py. The openai SDK is not used anywhere in the code; all API calls go through requests directly. This is a minimal, safe change that resolves the issue for all users following the standard install procedure.
