Transforming LLM Memory: Leveraging Context as Training Data to Enable Test-Time Learning in Models

Large Language Models (LLMs) are continually in the spotlight for their extensive context windows, yet they often struggle to maintain cohesive conversations without needing context repeated. Unlike humans, who adapt and learn from experiences, LLMs fail to remember previous interactions efficiently. This post discusses a significant advancement: Test-Time Training with an End-to-End formulation (TTT-E2E). Our research reveals that TTT-E2E effectively compresses context into model weights, enhancing performance in both loss and latency. As highlighted in Figure 1, while traditional models show diminishing returns, TTT-E2E stands out, achieving 2.7x faster inference for 128K context compared to typical transformers. This innovative method employs meta-learning during training to optimize next-token predictions, resembling how humans remember critical information. Although current limitations exist regarding the computational demands of TTT, ongoing developments aim to address these challenges.
