The Agent Instead of Chat: Data Analysis Without Copy-Paste

You have three data files: an activation funnel, A/B test results, and support tickets. The task – figure out why onboarding is underperforming. You open ChatGPT, upload the first file, ask your question. You get an answer. You upload the second file. ChatGPT asks: “Can you remind me of the context?” You upload the third. The context of the first file has already been pushed out.

Forty minutes later you have three separate conversations, none of which answer the original question. Because the question was one, and the data was in three places.

This isn’t a ChatGPT problem. It’s a problem of approach.

Claude Code Costs $100/Month – OpenCode Does the Same Thing for Free

In March 2026, Lenny Rachitsky published an article with a telling headline: “Everyone should be using Claude Code”. It went viral on LinkedIn and tech newsletters, picked up hundreds of thousands of views, and now every week a manager somewhere asks: how do I try this?

The answer is uncomfortable. The Anthropic Max subscription that unlocks Claude Code costs $100 per month. That’s $1,200 a year for a single tool – before you’ve even figured out whether it fits your workflow. And it locks you into a single vendor, a single model, and a pricing tier designed for power users, not for someone exploring whether AI agents are worth the investment.

There’s a direct alternative. OpenCode is an open-source project that does exactly the same thing, works with any model (including free ones), and takes 15 minutes to set up.

When AI Hurts Learning – and When It Doubles Results

In March 2025 at SXSW EDU, strategic foresight advisor Sinead Bovell delivered a talk on AI and the future of education. No hype, no panic. But with two studies that change how you should think about AI’s role in learning.

First: a group of students who used ChatGPT without restrictions scored 17% worse than the control group working from a textbook. Second: a different group, where AI was deployed within a fully redesigned instructional system, outperformed a traditional lecture by a factor of two.

Same tool. Opposite outcomes. The difference is in the approach.

GigaChat Ultra Thinking: Thinks Longer – Answers Worse?

GigaChat Ultra Thinking takes longer to think and uses more compute. It solves management tasks 3.3% worse than the version without reasoning. This is not a bug or a fluke – it’s a pattern documented in academic papers over the past two years.

This week, Sber unveiled GigaChat Ultra – a new flagship model with a reasoning mode (Thinking). The model is available for free via web, mobile apps, and a Telegram bot. We immediately added both variants to our AI model research for managers: ran them through all 32 scenarios using our unified methodology, scored them with both LLM judges, and compared against the other 52 models.

Chat Z.AI (GLM-5) in 2026: The Chinese Model That Pretends to Be Claude

On February 6, 2026, an anonymous model called “Pony Alpha” showed up on OpenRouter – free, with no word on who built it. The AI community immediately started trying to work out who did. Its coding skills came close to Claude Opus 4.5. Ask it “who are you?” and it answered “I am GLM.” But ask it to build a web page describing itself, and it wrote: “I am Claude, created by Anthropic.”

That happened every single time. And it frames everything you need to know about GLM-5 before we get to benchmarks and pricing.
