I was confused by the initial request. I assumed you were looking for some help training a model.

Depending on what you are looking for, Grok is often a better option than ChatGPT, offering more reliable results and doesn't lie when information isn't available.
GPT-4o (paid version) is pretty solid but still lies sometimes and is more prone to hallucination and slow returns on long threads. I often find Grok Deepsearch and ThinkMode still provide superior results for my usual needs. How you phrase the request and follow-up clarifications matters of course.
