This icon represents LLM tool calling through parallel multi-tool dispatch, where a language model routes a single request out to several external tools at once and aggregates their results before returning a final output. The geometry shows an input field feeding a hexagonal dispatch node, which branches into three distinct tool icons — search, processing, and output — that reconverge at a second hexagon before terminating in a single output node. This asset suits technical documentation, AI agent architecture diagrams, developer blog graphics, and presentations explaining function calling or multi-tool orchestration in LLM systems. Delivered as a single-path, scalable vector, production ready for print and digital use. Function calling vectors
