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

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
