Is This LLM Library Learning? Evaluation Must Account For Compute and Behaviour (2026.eacl-long)
Copied to clipboard
| Challenge: | Recent advances in the coding, reasoning, and tool-use ability of LLMs have raised the possibility of library learning with LLM. |
| Approach: | They propose to use reusable and composable functions and tools to create reusable, composesable code and tools that can be reused by modifying relevant examples. |
| Outcome: | The proposed system fails to consistently outperform the baseline model and does not correct for the difference in computational cost. |

| Challenge: | Large Language Models (LLMs) are capable of handling diverse tasks with well-crafted prompts and integration of external tools. |
| Approach: | They propose a prompt programming language that acts as a bridge between computer programs and LLMs by providing convenient conventions between them. |
| Outcome: | The proposed language is intuitive, concise, and efficient through representative scenarios including Chain-of-Thought with self-consistency (CoT-SC) and ReAct tool-use agent. |
