arXiv:2509.23292v4 Announce Type: replace Abstract: Tool-integrated reasoning (TIR) has become a key approach for improving large reasoning models (LRMs) on complex problems. Prior work has mainly studied when to invoke tools, while overlooking how tools are applied. We identify two common patterns: a calculator pattern that uses code for direct computation, and an algorithmic pattern that encodes problems as programs. Misaligned choices often cause failures even when reasoning is sound. We propose a two-stage framework that first builds code competence from both patterns and then aligns patte
The rapid advancement of large language models is moving beyond basic tool invocation to focus on more sophisticated and nuanced methods of integration to unlock greater capabilities and efficiency.
This research addresses a critical limitation in current AI tool use, moving from simple 'when' to 'how' tools are applied, which is essential for more robust and autonomous AI systems.
AI models will gain a deeper, pattern-aware understanding of tool utilization, leading to fewer failures due to misaligned tool choices and more complex problem-solving abilities.
