New OoO-Spec method drastically speeds up LLM tool calling

Researchers have developed OoO-Spec, a novel method to accelerate tool calling in large language models (LLMs). This technique utilizes a smaller Qwen3-0.6B model as a sidecar to predict function choices and argument values in parallel, significantly speeding up the process compared to traditional token-by-token generation. OoO-Spec achieved up to a 5.34x speedup over autoregressive decoding and outperformed existing methods like ToolSpec, demonstrating its effectiveness across various LLM targets and benchmarks. AI

IMPACT Accelerates LLM inference speed for tool-using applications by enabling parallel processing of function calls and arguments.
