RoboTTT Extends Robot Memory to 5 Minutes
seanmcdonaldxyz · x · 2026-07-16
This reply introduces RoboTTT: a robotic policy that embeds test-time training (TTT) directly inside the model.
Key points include:
- Robotic models typically remember only extremely short time slices (under 0.1 seconds), forgetting immediate events almost instantly.
- RoboTTT expands the context to 8,000 timesteps, equivalent to roughly 5 minutes of "muscle memory."
- The author states this is achieved at a constant inference cost, outperforming current SOTA capabilities by 3 orders of magnitude.
- The core concept involves having a tiny model "live" inside a larger model, continuously updating as it processes each new input.
