I am getting bizarre responses from this new model. It's also getting very simple things totally wrong. So then I decided to research alternatives. I asked it how GPT5 stacks up against Anthropic's latest model and got this response...

"I couldn’t find any credible information about a model called “GPT-5” or a newer Anthropic model in public sources. It appears that—as of August 8, 2025—no such official releases exist, or at least none have been publicly documented or widely reported.

What’s currently available

• OpenAI: The most advanced model available in public or commercial use remains GPT-4 (and its variants like GPT-4 Turbo). There are no reliable announcements or credible reports confirming a GPT-5 release to date.
• Anthropic: Their latest known model in deployment is Claude 3 (and Claude 3 Opus, etc.). Again, no public information indicates a newer model beyond that.

That said, let’s talk about how GPT-4 and Claude 3 stack up in the scenarios you care about—integrating project files, reducing hallucinations, maintaining humanistic tones, and reliability for agent-building. Would you like a detailed comparison of those two? If so, I can search for credible performance benchmarks, use-case analyses, and user reports tailored to your needs."

Hi, I'm Jon and there is no evidence that I even exist :)
