Practical articles on Claude Code, agentic development, and the AI coding market.https://www.vibecoding.cz/enhttps://www.vibecoding.cz/en/when-harari-talks-about-ai-after-a-booed-macinka/https://www.vibecoding.cz/en/when-harari-talks-about-ai-after-a-booed-macinka/At a surreal conference hosted by a billionaire's wife, Foreign Minister Petr Macinka spoke about migration first, and then the sociohistorian Yuval Noah Harari talked about AI as a form of migration. The contrast could not have been greater.Tue, 13 Oct 2026 00:00:00 GMThttps://www.vibecoding.cz/en/decision-models-cheap-ai-that-picks-the-right-answer/https://www.vibecoding.cz/en/decision-models-cheap-ai-that-picks-the-right-answer/Did you pull the right data out of a document? Did you correctly detect the OK button in an interface? Decision models handle this better than a regular LLM. Jev started it, and within two weeks more than ten models appeared around this problem. Cloudflare, Perplexity, Amazon and OpenAI have all entered the game. I'll show you how to find your way around them, what they cost and, above all, which tasks they're really good for.Mon, 05 Oct 2026 00:00:00 GMThttps://www.vibecoding.cz/en/mods-for-claude-code-anthropic-lets-you-under-the-hood/https://www.vibecoding.cz/en/mods-for-claude-code-anthropic-lets-you-under-the-hood/What has always annoyed me about Claude Code is how it prints colorful diffs while it works, and I don't want to read them. But there was no way to hide them. Until now: Anthropic has introduced Mods, which let you properly rebuild the interface.Fri, 02 Oct 2026 00:00:00 GMThttps://www.vibecoding.cz/en/openai-devday-2026-dots-personal-agents-and-other-news/https://www.vibecoding.cz/en/openai-devday-2026-dots-personal-agents-and-other-news/At DevDay 2026, OpenAI announced more than twenty new things. For us vibecoders, there are three main themes: Dots as agents that work continuously, an upgraded Codex as an environment for delegated development, and an expanded platform for custom apps and automations. I won't leave the GPT-6.1 model aside either. Let's go through it all.Wed, 30 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/the-200-codex-pro-plan-is-back-with-half-the-volume/https://www.vibecoding.cz/en/the-200-codex-pro-plan-is-back-with-half-the-volume/Not long ago, OpenAI pulled its $200 plan because of high demand. Now it's bringing it back, reworked. How much work does a $200-a-month subscription actually buy you?Tue, 29 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/who-profits-when-you-run-an-llm-at-home/https://www.vibecoding.cz/en/who-profits-when-you-run-an-llm-at-home/Lately there's a lot going on around locally run LLMs. Performance keeps rising, and with it the hope that we can get rid of subscriptions to closed models. But things are boiling under the surface. Why would NVIDIA buy Hugging Face for $13 billion, when its most famous piece of software, llama.cpp, runs AI on hardware NVIDIA doesn't sell? Let's take a look at this world.Mon, 21 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/jev-the-model-that-doesnt-write-it-just-decides-how-to-use-it-and-when-it-pays-off/https://www.vibecoding.cz/en/jev-the-model-that-doesnt-write-it-just-decides-how-to-use-it-and-when-it-pays-off/It has the AI community buzzing. Jev from TypeSafe can't write a single sentence, but for a fraction of the price of Haiku it answers a yes/no question, picks from a list of options or gives a score. So I went to try it out...Sat, 19 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/claude-code-projects-now-split-up-the-work-on-their-own/https://www.vibecoding.cz/en/claude-code-projects-now-split-up-the-work-on-their-own/Anthropic has just launched redesigned Projects in Claude Code. A project is now a single long-running conversation in which Claude acts as a coordinator. It breaks the assignment into individual threads, each run as a separate session on its own branch, and they report their results back.Fri, 18 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/cerna-ai-festival-lit-up-ostrava/https://www.vibecoding.cz/en/cerna-ai-festival-lit-up-ostrava/A beautifully designed event, both visually and in its programming, set in the striking surroundings of the former Vítkovice ironworks. It was well worth attending, and it raised the bar for events in the Czech Republic. So what was it about?Wed, 16 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/how-to-tell-a-good-ai-workshop-from-a-bad-one/https://www.vibecoding.cz/en/how-to-tell-a-good-ai-workshop-from-a-bad-one/The debate about the quality of the various AI trainings, and especially of the trainers themselves, has resurfaced lately. A few experiences and a view from the inside might be useful here.Mon, 14 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/cursor-projects-shows-a-great-new-approach-to-managing-agents/https://www.vibecoding.cz/en/cursor-projects-shows-a-great-new-approach-to-managing-agents/How do you make AI developer tools better? How do you fix the way they handle context so they don't slow you down as a human, and by extension don't slow down the AI agents either? Cursor Projects is trying to answer that. I can't wait for the others to copy it! Sun, 13 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/anthropics-head-of-ai-safety-testing-we-dont-have-a-plan-yet-for-aligning/https://www.vibecoding.cz/en/anthropics-head-of-ai-safety-testing-we-dont-have-a-plan-yet-for-aligning/At the beginning of September, Jacob Coxon announced he was leaving Anthropic. The name probably won't mean anything to you: he did pre-training research on models, earlier at OpenAI, most recently at Anthropic. He accompanied his resignation with a thread on X that took off immediately. In it, he claims that both OpenAI and Anthropic are heading toward self-improving superintelligence in a way he doesn't consider responsible.Wed, 09 Sep 2026 00:00:00 GMThttps://www.vibecoding.cz/en/openclaw-2-0-does-multiplayer-watch-out-for-it/https://www.vibecoding.cz/en/openclaw-2-0-does-multiplayer-watch-out-for-it/It's tempting. One agent, one machine, a whole team in a single thread, with work handed off along with its context. The new version of OpenClaw lures you in with support for multiple users in one installation, in one thread. Limits? There are some!Mon, 31 Aug 2026 00:00:00 GMThttps://www.vibecoding.cz/en/the-case-of-openais-rogue-ai-agents-attacking-hugging-face/https://www.vibecoding.cz/en/the-case-of-openais-rogue-ai-agents-attacking-hugging-face/A month ago, a widely reported case saw OpenAI's AI agents attack Hugging Face servers. Now it has a resolution. The company itself published a technical report, and an independent investigation has come out as well. The two stories diverge somewhat, and they are more alarming than they first appeared.Fri, 28 Aug 2026 00:00:00 GMThttps://www.vibecoding.cz/en/hardware-for-local-ai-what-to-buy-in-august-2026-and-whether-it-pays-off/https://www.vibecoding.cz/en/hardware-for-local-ai-what-to-buy-in-august-2026-and-whether-it-pays-off/It's incredibly tempting. You buy an AI computer and run local models for the cost of a hardware installment plan. For this game to add up, the hardware has to be available, open models have to be strong enough, and the prices of the closed ones can't collapse. So what should you pick?Wed, 26 Aug 2026 00:00:00 GMThttps://www.vibecoding.cz/en/an-ai-watermark-proves-touch-not-authorship-what-should-we-do-about-labeling-ai-content/https://www.vibecoding.cz/en/an-ai-watermark-proves-touch-not-authorship-what-should-we-do-about-labeling-ai-content/On Monday, Anthropic confirmed that it embeds an invisible watermark in text generated by Claude. The hate toward the EU started immediately, blaming it for the move, but the EU requires nothing of the sort. Where are the limits of AI in text, and how do I use AI to write my own?Wed, 12 Aug 2026 00:00:00 GMThttps://www.vibecoding.cz/en/the-agent-deleted-someone-elses-booking-what-ai-agents-do-to-a-sloppy-saas/https://www.vibecoding.cz/en/the-agent-deleted-someone-elses-booking-what-ai-agents-do-to-a-sloppy-saas/An Australian user asked OpenClaw to book a gym class. The agent found a missing ownership check in the booking API and canceled a stranger's reservation.
