Root Cause

Input exceeded context window and was silently truncated, losing important context.

generic

Workarounds

  1. 85% success Implement chunking with overlap for long documents 
    Split into chunks of 75% context window with 10% overlap
  2. 80% success Use models with larger context windows 
    GPT-4 Turbo 128K, Claude 200K, Gemini 1M

Dead Ends

Common approaches that don't work:

  1. Just increase max_tokens parameter 85% fail

    max_tokens controls output length, not input window size.

  2. Compress text by removing whitespace 70% fail

    Tokens are not bytes - whitespace removal saves minimal tokens.
