NodeLLM 1.17 adds opt-in parallel tool execution

[eshaiju]

When a model returns several independent tool calls in the same turn, NodeLLM has always run them one at a time. That's safe by default, but wastes time when the calls don't depend on each other — three weather lookups for three cities, say. Enable toolConcurrency to run them in parallel instead:

const chat = llm.chat("gpt-4o-mini")
  .withTool(WeatherTool)
  .withToolConcurrency(true);

await chat.ask("What is the weather in Tokyo, London, and New York?");

Works the same way in stream() and Agent mode — no changes needed to how your tools are defined.

Upgrade: npm install @node-llm/core@1.17.0
