What this does and does not show.
- Counted from ChatGPT’s 15 usable answers of 15 planned.
- Products level on share of answers and average position share a rank: the measurement shows no difference between them.
- Counted as one product under reviewed spellings: “Google Agent Development Kit” as Google ADK; “Haystack (deepset)” as Haystack; “Microsoft Agent Framework (AutoGen + Semantic Kernel)” as Microsoft Agent Framework; “AutoGen” and “AutoGen (Microsoft)” as Microsoft AutoGen; “OpenAI Agents SDK (Python)” as OpenAI Agents SDK; “Microsoft Semantic Kernel” as Semantic Kernel.
- AI answers vary from run to run and with each person’s history and settings. This is what ChatGPT answered on 9 October 2026, asked fresh each time, not what every user will see.
- One engine and one month. Another engine, or next month, can name different products.
