The canonical sequence of tool streaming chunks according to OpenAI documentation looks like this:
[{"index": 0, "id": "call_DdmO9pD3xa9XTPNJ32zg2hcA", "function": {"arguments": "", "name": "get_weather"}, "type": "function"}] [{"index": 0, "id": null, "function": {"arguments": "{\"", "name": null}, "type": null}] [{"index": 0, "id": null, "function": {"arguments": "location", "name": null}, "type": null}] [{"index": 0, "id": null, "function": {"arguments": "\":\"", "name": null}, "type": null}] [{"index": 0, "id": null, "function": {"arguments": "Paris", "name": null}, "type": null}] [{"index": 0, "id": null, "function": {"arguments": ",", "name": null}, "type": null}] [{"index": 0, "id": null, "function": {"arguments": " France", "name": null}, "type": null}] [{"index": 0, "id": null, "function": {"arguments": "\"}", "name": null}, "type": null}] nullIn ollama's case (tested on
llama3.2:3bat least) the sequence of chunks is different, the first chunk can already contain theargumentsstring.This should close #1502
