The MetaGPT team introduced Latent Action Reparameterization (LAR) in a NeurIPS 2026 paper. This method compresses frequent, stable multi-step text actions in agent trajectories into single 'latent actions,' effectively shortening the decision chain. Experiments show that LAR significantly reduces token consumption and improves inference efficiency by addressing the bottleneck of long action sequences rather than just optimizing per-step speed.

MetaGPT Proposes LAR Framework to Compress Action Chains and Cut Agent Inference Costs
- LAR encodes repetitive multi-step action sequences into learnable latent action units
- Reduces overall inference cost by minimizing effective decision steps rather than just accelerating per-step generation
- Accepted at NeurIPS 2026, demonstrating approximately 27% reduction in token consumption
