🔍 Claude Model Usage Review

Summary

I've reviewed all changed files for Claude model usage. Found several deprecated models and opportunities for improvement.

❌ Issues Found

1. Deprecated Claude 2.x Models

  • third_party/Pinecone/rag_using_pinecone.ipynb:398 - Uses claude-2.1 (legacy/deprecated)
  • third_party/Wikipedia/wikipedia-search-cookbook.ipynb:434 - Uses claude-2 (legacy/deprecated)

2. Suboptimal Model References

Multiple files use specific dated versions instead of -latest aliases:

  • claude-3-5-sonnet-20241022 appears in 13+ files
  • claude-3-haiku-20240307 appears in 10+ files
  • claude-3-opus-20240229 appears in 6+ files

✅ Valid Models Found

  • claude-3-7-sonnet-20250219 (Claude Sonnet 3.7)
  • claude-3-5-sonnet-20241022 (valid but could use -latest alias)
  • claude-3-haiku-20240307 (Claude Haiku 3)
  • claude-3-opus-20240229 (Claude Opus 3)

🔧 Recommendations

High Priority

  1. Update deprecated Claude 2.x models to current versions:
    • claude-2.1claude-3-7-sonnet-latest or claude-3-haiku-20240307
    • claude-2claude-3-7-sonnet-latest or claude-3-haiku-20240307

Medium Priority

  1. Consider using -latest aliases for better maintainability:
    • claude-3-5-sonnet-20241022claude-3-7-sonnet-latest
    • claude-3-haiku-20240307 → Current version (no -latest alias available)

Low Priority

  1. Review data files containing old model references in documentation to avoid user confusion

Current Public Models (as of documentation)

  • Claude Sonnet 4.5: claude-sonnet-4-5-20250929
  • Claude Sonnet 4: claude-sonnet-4-20250514
  • Claude Sonnet 3.7: claude-3-7-sonnet-20250219 (alias: claude-3-7-sonnet-latest)
  • Claude Opus 4.1: claude-opus-4-1-20250805
  • Claude Opus 4: claude-opus-4-20250514
  • Claude Haiku 3.5: claude-3-5-haiku-20241022 (alias: claude-3-5-haiku-latest)
  • Claude Haiku 3: claude-3-haiku-20240307

Note: Claude 3.5 Sonnet and Claude Opus 3 are deprecated according to current documentation.
