- gptcache/adapter/anthropic.py: Claude messages adapter (sync/async/streaming) - gptcache/adapter/openai_client.py: adapter for openai>=1.0 client interface - utils: import_anthropic/import_openai_client helpers + anthropic response extractors - core: cache.set_anthropic_key()
Uses TypeSafe's Jev model via five atomic noul checks (task identity, context, format, freshness, missing context). The score is the minimum across dimensions, so a cache entry is reused only when every condition passes the similarity threshold.
