A 3‑model comparison copilot that answers analytical questions using OpenAI GPT‑5.2, Gemini Pro 3, and Claude 4.5 Sonnet side‑by‑side. For each analytical prompt, it generates GPT‑5.2’s response, calls Gemini Pro 3 and Claude Sonnet with the user’s prompt verbatim, and returns all three answers in clearly separated sections so you can compare reasoning, tone, and completeness. If a model call fails, it still shows the available answers and flags the failure.
