| Challenge: | Existing benchmarks that assess Language Models (LMs) as Language Agents (LAs) for tool use focus on stateless, single-turn interactions or partial evaluations, overlooking the inherent stateful nature of interactions in multi-turn applications. |
| Approach: | They propose a multi-turn dialogue dataset with stateful tool interactions considering the whole life cycle of tool use across six key tasks in three stages . they also build VirtualMobile – an embodied virtual mobile evaluation environment to simulate API calls and assess the robustness of the created APIs. |
| Outcome: | The proposed dataset evaluates 13 open- and closed-source LLMs and provides detailed analysis at each stage. |

| Challenge: | Existing Language Agents neglect the notion of uncertainty during interactions with external worlds. |
| Approach: | They propose a framework that orchestrates the interaction between the agent and the external world using uncertainty quantification. |
| Outcome: | The proposed framework improves performance on 3 representative tasks and lowers reliance on external world. |

| Challenge: | Large Language Models (LLMs) have gained popularity due to their ability to generate human-like text and solve complex tasks. |
| Approach: | They propose an offline reinforcement learning technique that augments a semantic memory based on experiential learnings from past trials. |
| Outcome: | The proposed technique boosts Language agents’ performance by 4 % to 16.82 % over the raw GPT-4 baseline and performs on par with existing state-of-the-art prompt optimization techniques while requiring fewer LLM calls. |

| Challenge: | Large Language Models (LLMs) with API-calling capabilities enabled building effective Language Agents (LA) current approaches excel in one domain but underperform in the other. |
| Approach: | They propose a unified approach that integrates both conversational and agentic capabilities. |
| Outcome: | The proposed model outperforms top domain-specific models across three benchmarks. |
