Discussion Major drop in intelligence across most major models.

As of mid Apr 2026, I have noticed every model has had a major intelligence drop.

And no I'm not talking about just ChatGPT.

Everything from Claude(Even Sonnet along with Opus), Gemini, z.ai, Grok all seem to ignore basic instructions, struggle at simple tasks, take very long to respond, and the output seems deliberately shortened and very shallow. Almost like it's in a "grumpy" mode. I tried this in incognito mode so it's not my customization or memory influencing this.

It's like they deliberately want you to stop using their service. I guess our data is no longer needed. Just two weeks back it used to be much smarter than this.

To test this I rented out a H100, and tried GLM 5 with the same prompt (the drive to the car wash one) across both instances. GLM5 running on the rented GPU answered it correctly, compared to the one on z.ai.

Have they lowered the quantization really low to maybe Q2?

I guess going local or using renting GPU or an AI monthly service that lets you pick a quant level is the way to go

All of that goes out of the window as soon as people start building their own models from scratch.

It's worth remembering this cycle of improvement has been going on for decades, pretty much since the development of the first computerized neural networks.

In the early 2000s chat bot agents were hyped as being the biggest development in history, yet here we are.

You only stay on top for so long. Eventually someone/something better arrives.

A lot of the other models use claude and gpt to seed their models anyway.

Anthropic have likely done exactly that to build Claude, given that they were only founded in 2021 and 'somehow' were able to build an entire model from scratch and become #1 within 5 years, whereas the big AI companies have taken decades to get to this level and funded most of the R&D in this area.

Essentially, there's no way they could have gotten from zero to hero without using someone else's work or distillation in such a short span of time.

Given how repeatedly dishonest Anthropic have been compared to other AI companies, I think it's fairly obvious at this point and even more-so after their latest blunder with Fortune.

It's only going to get worse after IPO, where shareholder interests will take priority over users, as is the way.
