Agent memory systems with A2A protocol support

Google DeepMind's Gemini Robotics + Gemini Robotics-ER (Embodied Reasoning) released Mar-2025. VLA models built on Gemini 2.0 backbone. Reference platform: Apptronik Apollo. The DeepMind line of robotics-FM, descendant of earlier RT-1 / …

Treats memory as first-class in multi-agent tracing. Luna-2 SLMs (3B / 8B) scan every interaction for intent drift and belief drift; 20+ checks at sub-200ms latency. Catches when agent A's view of the world splits from teammate B's. Open…

GA at Google Cloud Next 2026 (2026-04-22). Vertex AI rebranded as Gemini Enterprise Agent Platform; Memory Bank now "Agent Platform Memory Bank" with new continuous event-streaming + automated memory generation triggered by configurable …

Personal Context setting + Personal Intelligence packing. Memory import from ChatGPT/Claude (Mar 2026).

Microsoft 365 Copilot memory stored in user's Exchange mailbox with compliance alignment. GA Jul 2025.

Google DeepMind's experimental browser agent built on Gemini 2.0 — Chrome extension that takes actions on the user's behalf. Research-preview launched Dec 2024. The Google answer to OpenAI Operator / Anthropic Computer Use; integrated in…

Distinct from LangMem. Built-in checkpointer saves graph state per super-step (short-term, thread-scoped). Store System adds long-term hierarchical key-value memory across threads with optional vector search + TTL. Postgres / Mongo / Red…

Google's Agent Development Kit. Session services: InMemory / Database / VertexAI. Long-term: InMemoryMemoryService or VertexAIMemoryBankService (uses Vertex AI Memory Bank Preview for persistent cross-session memory).

First-class memory module inside LangChain — explicit cognitive-science-style typing of memories.

Two-tier model: ChatMessage FIFO queue with overflow flushed into long-term Memory Block objects. Memory class replacing older ChatMemoryBuffer.

TypeScript-first agent framework. Default memory: LibSQL store + on-device fastembed-js for semantic recall.

Cross-Model Verification Kernel (CMVK) requires majority-voting agreement across multiple model calls before a memory-influenced action. Agent OS package intercepts every action (memory included) at sub-millisecond latency. MIT licensed.

Pydantic-AI ships no native persistent memory; agents start fresh each run. Long-term memory typically added via third-party integration (e.g. Hindsight) using tools + auto-injected memory instructions.

Microsoft Semantic Kernel's memory plugin ( Microsoft.SemanticKernel.Plugins.Memory ). Plug-in approach to long-term memory in the SK agent framework.

AWS code-first agent framework. Multi-LLM (Bedrock, Anthropic, Gemini, OpenAI). Memory via Mem0 integration (ElastiCache for Valkey + Neptune Analytics) or Bedrock AgentCore Memory. Local default uses FAISS; OpenSearch for production.

Google Cloud managed memory service (Preview). Used by ADK's VertexAIMemoryBankService for cross-session persistent memory. Intelligently stores and retrieves memories from past user interactions.

Memory exposed via Anthropic SDK's BetaAbstractMemoryTool when Anthropic provider is active. No built-in persistent storage in the framework itself. Other providers require external memory (Hindsight, Mem0) wired in manually.
