At this point, any article that makes claims about "LLMs" rather than specific model versions lacks credibility.
The current version of GPT-4 is very different from most existing LLMs (including the previous version of ChatGPT). The next version release will also be different.
Google just released PaLM 2 publicly. It is significantly better than what people saw with the initial Bard versions. They have a code-generation model that is not released publicly yet.
The open source models are also gaining capabilities and get new releases routinely.
Claude now has a new release with 100K tokens.
All of these will perform differently on the negation issue.
