NTILC: Neural Tool Invocation via Learned Compression

arXiv:2606.06566v1 Announce Type: cross Abstract: Agentic tool-calling language models depend on large registries of callable APIs, functions, and local actions. Placing full tool specifications directly in the prompt incurs a cost that scales linearly with the size of the tool registry, rapidly consuming the context budget. As the registry grows, this leads to higher latency and degrades selection accuracy, particularly due to interference from irrelevant tools. We overcome these limitations by introducing NTILC, a neural tool selection and invocation framework that replaces in-context regist

Why this matters
Why now

The development of more sophisticated AI agents and the expansion of callable API registries necessitate new methods for efficient tool invocation to overcome current context window limitations.

Why it’s important

This development addresses a critical scaling bottleneck for agentic AI, potentially accelerating their adoption and capability by making tool use more efficient and less resource-intensive.

What changes

Current linear scaling costs for agentic tool invocation are replaced with a more efficient, learned compression method, allowing AI agents to utilize larger tool registries without performance degradation.
