Google Titans + MIRAS: The AI Memory Breakthrough That Changes Everything

Key Takeaways

  • Google's Titans + MIRAS architecture combines RNN efficiency (O(n) vs Transformer's O(n²)) with Transformer-quality understanding, achieving 5x faster processing for sequences over 100K tokens with real-time memory updates.
  • The breakthrough enables continuous learning during inference — agents update their knowledge on the fly without retraining, maintaining 94% recall accuracy after 1M tokens and 87% after 10M tokens.
  • Practical capabilities unlocked: learning conversations that improve over time, multi-day project continuity without recaps, personalization that adapts to user preferences, and relationship memory that builds rapport across sessions.
  • Rollout plan: API access for developers in Q1 2026, integration in Google products Q2 2026, general availability Q3 2026, and open-source implementation in Q4 2026.

Titans + MIRAS: Google's AI Memory Breakthrough

Google has unveiled a major architecture that overcomes one of AI's fundamental limitations: Titans + MIRAS combines RNN speed with Transformer performance, enabling real-time memory updates that allow AI to learn on the fly.

The Memory Problem

Traditional Transformers:

  • Fixed context windows (even with 2M tokens)
  • Can't update knowledge without retraining
  • Forget earlier context in long interactions
  • Static memory during inference

The Challenge: An agent interacting over hours/days can't learn from the conversation—it treats each exchange independently.

Titans + MIRAS Solution

Titans: The Foundation

  • Novel architecture blending RNN and Transformer strengths
  • Recurrent processing for sequential memory
  • Attention mechanisms for relevant recall
  • Efficient processing of long sequences

MIRAS: Memory Integration

  • Real-time memory updates during inference
  • No retraining required
  • Persistent learning across sessions
  • Context-aware knowledge integration

How It Works

Traditional Flow:

Input → Process → Output
(Memory fixed throughout)

Titans + MIRAS Flow:

Input → Process → Update Memory → Output
   ↑         ↓
   └─────────┘
(Memory evolves in real-time)

Performance Advantages

Speed:

  • RNN-like efficiency: O(n) vs Transformer's O(n²)
  • 5x faster processing for sequences over 100K tokens
  • Real-time updates without batch retraining

Quality:

  • Transformer-level understanding and generation
  • Better long-range dependency handling
  • Context-aware responses across sessions

Memory:

  • Continuous learning from interactions
  • Persistent knowledge across conversations
  • Selective memory retention (important vs. trivial)

Breakthrough Capabilities

What This Enables:

  • Learning Conversations: Agent improves understanding of you over time
  • Project Continuity: Maintains context across days/weeks
  • Personalization: Adapts to individual user preferences
  • Knowledge Building: Accumulates domain expertise during deployment
  • Relationship Memory: Recalls past interactions and builds rapport

Real-World Applications

Customer Service:

  • Remember customer preferences across calls
  • Build relationship over time
  • Learn company-specific knowledge
  • Improve responses based on feedback

Personal Assistants:

  • Learn your communication style
  • Remember your priorities and preferences
  • Adapt to changing needs
  • Build long-term context

Research Agents:

  • Accumulate domain knowledge during research
  • Remember findings from earlier searches
  • Build comprehensive understanding over time
  • Connect insights across sessions

Business Agents:

  • Learn organizational processes
  • Remember stakeholder preferences
  • Adapt to company culture
  • Improve over time without retraining

Technical Innovations

Hybrid Architecture:

  • Recurrent state for sequential processing
  • Attention for relevant memory recall
  • Best of both paradigms

Selective Memory:

  • Importance scoring for information
  • Automatic pruning of irrelevant details
  • Compression of redundant knowledge

Real-Time Updates:

  • On-the-fly memory modification
  • No training pipeline required
  • Immediate integration of new information

Persistent Storage:

  • Memory survives across sessions
  • Long-term knowledge retention
  • Efficient serialization/deserialization

Comparison to Alternatives

vs. RAG (Retrieval-Augmented Generation):

  • RAG: External database, slower retrieval
  • Titans+MIRAS: Integrated memory, instant access

vs. Fine-Tuning:

  • Fine-tuning: Requires retraining, expensive
  • Titans+MIRAS: Real-time updates, no retraining

vs. Long Context Windows:

  • Long context: Still limited, no learning
  • Titans+MIRAS: Unlimited timeline, continuous learning

Overcoming Context Limits

The 2M Token Limit Problem:

Even with enormous context windows, agents face limits. Titans+MIRAS transcends this:

  • Selective Compression: Important info retained, details compressed
  • Hierarchical Memory: Summary at high level, details when needed
  • Dynamic Retrieval: Pull relevant memories as needed
  • Continuous Evolution: Memory structure adapts over time

Extended Scenario Capabilities

Multi-Day Projects:

  • Day 1: Initial briefing and setup
  • Day 2: Continue where left off, no recap needed
  • Day 3: Build on accumulated understanding
  • Week 2: Expert-level context on project

Long-Term Relationships:

  • Month 1: Learning preferences
  • Month 3: Personalized service
  • Month 6: Anticipating needs
  • Year 1: Deep understanding of user
