The capabilities of LLM Agents depend heavily on the interaction interface used during training, and semantically equivalent but differently expressed interfaces (such as changing an action name from search to lookup, or changing parameters from JSON to YAML) can cause a marked decline in their performance.

UnverifiedThe LLM training and inference pipeline includes stages such as tokenization, embedding layers, self-attention mechanisms, feed-forward networks, and residual connections.67% similarUnverifiedExisting interface randomization strategies can only extend the Agent's dependence on the interface from a 'single interface' to the 'training interface distribution', and out-of-distribution perturbations still lead to degradation in Agent performance.66% similarUnverifiedFoundation models for agent tasks differ markedly in training objectives from models for general conversation; the former place more emphasis on tool calling, multi-step planning, error recovery and the ability to use environmental feedback, and their training data often contains a large number of stateful interaction trajectories.65% similarUnverifiedIn long task chains for LLM Agents, meaningful reward signals may only appear upon final task completion, making it difficult to correctly attribute credit to intermediate steps—a phenomenon in reinforcement learning known as the "credit assignment problem."64% similar
