LingBot-VLA 2.0

From Foundation to Application: Improving VLA Models in Practice

Scaling up Pre‑training Dataset

LingBot‑VLA 2.0 scales pre‑training with a broader data mixture: 50,000 hours of real robotic data and 10,000 hours of embodiment‑free egocentric manipulation data.

Diverse Robot Source ~50000 hours
Diverse Ego Source ~10000 hours

Data processing pipeline

The raw pool is split into robotic and egocentric streams, then filtered stage by stage. Gray bands represent rejected data; colored blocks are retained and passed forward.

Sparse MoE

LingBot‑VLA 2.0 adopts a sparse MoE architecture to achieve more efficient scaling. Under the same active parameter budget, MoE consistently attains lower training loss and validation error than its dense counterpart, demonstrating the superiority across both optimization and generalization metrics.
