33 AI Models for Managers: Why We Need Your Ratings

11 min read

Over the past year, 33 new AI models have appeared on the market, each claiming the title of “best manager’s assistant.” ChatGPT updated to GPT-5.2, Claude released Opus 4.5, Gemini added a new Pro version, Yandex and Sber announced further improvements, and Chinese models went OpenSource. How do you choose a tool when every one of them promises a productivity revolution? We decided to run a large-scale comparative study – but ran into a problem that may seem paradoxical.

The Hidden AI Tax: Why 40% of Time Savings Disappear

87% of employees use AI at work. 77% say they’ve become more productive. Sounds like a digital transformation success story. But ask the uncomfortable question: if AI boosts productivity so effectively, why do only 14% actually see net gains? Where do the other 86% go?

Workday conducted a global study with 3,200 respondents – and found that behind the impressive numbers lies an inconvenient reality. Nearly 40% of time saved with AI is spent fixing its mistakes. This isn’t a bug in specific tools, nor a problem of “incorrect usage.” It’s a systemic failure in how organisations deploy artificial intelligence.

At mysummit.school, we’ve previously covered Dejan.AI (AI as a junior intern), Gallup (usage doubling in a year), and MIT (the gap between leaders and laggards). Workday adds a new angle: the measurable cost of low-quality AI output. And that cost turns out to be higher than many are willing to admit.

86% of Students Use AI, But Are Getting Worse. One Experiment Changed Everything

Traditional approaches to education are breaking down. AI writes essays and papers in minutes – and that has permanently changed the purpose of creative assignments in schools. Banning neural networks doesn’t work, and isolating students from technology is a dead end. The question is not whether to use AI. The question is how to use it so the technology develops students’ skills rather than replacing their thinking.

45% of Americans Use AI Annually: Gallup 2025 Data and What Changed in a Year

Gallup – one of the oldest polling organizations in the US – has released fresh data on how Americans used artificial intelligence in 2025. We’ve already covered Stanford (37% personal use), Brookings (57% use AI, but only 19% see results), and Wharton (82% of executives use it weekly). Now we have Gallup’s numbers – and they point to an important trend: usage is growing, but more slowly than the hype suggests.

82% of Executives Use AI Weekly: How AI Penetrates Industries – Wharton 2025 Report

For the third year running, Wharton School of Business and GBK Collective have been tracking how US companies deploy generative AI. The fresh October 2025 numbers tell a clear story: the technology has moved from experiment to daily practice. In a previous article we looked at the gap between rank-and-file AI use (19% see results) and corporate projects (80% succeed). The new Wharton report shows exactly how companies get to that 80% – and why results differ across industries.
