Definition and scope

What this capability means

This row concerns model-request prompt or context caching: eligible repeated prefixes receive documented processing, latency, or billing reuse. It does not include browser caches, downloaded-file caches, embedding indexes, retrieval caches, build caches, or a conversation merely retaining its history.

Evidence should identify whether reuse is automatic or explicit, minimum eligible prefix size, exact-prefix requirements, supported models and regions, cache lifetime, isolation boundary, invalidation behavior, and read-versus-write pricing. A model API feature does not prove that a hosted chat or coding harness preserves stable prefixes or passes cache controls through.

Evidence
  1. 1. Evidence checked 2026-08-28: Claude Code documents automatic prefix-based prompt caching for its system prompt, project context, conversation history, and tool results, with explicit invalidation behavior.
  2. 2. Evidence checked 2026-08-28: Gemini CLI documents automatic token caching for Gemini API-key and Vertex AI authentication, while OAuth through Code Assist does not support cached-content creation.
