 ### Changes
 - Memory: add OpenAI Batch API indexing for embeddings when configured.
+- Memory: enable OpenAI batch indexing by default for OpenAI embeddings.
 
 ### Fixes
 - Memory: retry transient 5xx errors (Cloudflare) during embedding indexing.

 Batch indexing (OpenAI only):
-- Set `agents.defaults.memorySearch.remote.batch.enabled = true` to submit embeddings via the OpenAI Batch API.
+- Enabled by default for OpenAI embeddings. Set `agents.defaults.memorySearch.remote.batch.enabled = false` to disable.
 - Default behavior waits for batch completion; tune `remote.batch.wait`, `remote.batch.pollIntervalMs`, and `remote.batch.timeoutMinutes` if needed.
 - Batch mode currently applies only when `memorySearch.provider = "openai"` and uses your OpenAI API key.
