This operation combines all memories into a single comprehensive summary, achieving maximum token reduction while preserving all key information. To use a custom model, specify the model parameter in 'provider:model_id' format (e.g., 'openai:gpt-4o-mini', 'anthropic:claude-3-5-sonnet-20241022'). If not specified, uses MemoryManager's default model (gpt-4o). Set apply=false to preview optimization results without saving to database. ## OpenAPI ````yaml /reference-api/openapi.yaml post /optimize-memories openapi: 3.1.0 info: title: Agno API Reference description: The all-in-one, private, secure agent platform that runs in your cloud. version: 2.5.6 servers: [] security: [] paths: /optimize-memories: post: tags: - Memory summary: Optimize User Memories description: >- Optimize all memories for a given user using the default summarize strategy.
