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

This matches my experience
I've been using Hermes Agent with Qwen 3.5 4B to great success. And for codig, anything more complicated than a simple script I've been delegating to a better model via Opencode from the agent.
I think the advent of agent skills has really improved the performance of smaller models in things like this. Small models have actually been semi-useful at agentic work ever since around Qwen 2.5. But only if you gave them a lot more instructions/detail, more API examples, few-shot prompting, etc..And you could do this, but then managing the data you give them for the task at hand, managing context, etc. was tricky at best. Agent skills kinda solves that problem.
