Tak sice později než jsem říkal, ale hotovo. Zítra pošlu pozvánku na meetup.

Nevystavuj mé trollící já pokušení, @josefslerka.bsky.social, já prožil s R spoustu krásných let! Nebo kliknu na na "Yes" a... Může mít počítačový jazyk pohřeb? S Always Look on the Bright Side of Life? Že bychom pozvali Rkaře na #pycamp a #pyvo?

This is actually pretty good illustration of AI-assisted coding success / failure (ignore the term "vibe coding" and be honest - we have all been on the 4th line)

Ok, this is crazy. Geoguessing photos with AI:
* Gemini 2.5 Pro seems to be the best (crazy how fast it is!)
* OpenAI o4-mini-high (on a screenshot) - not bad!
* OpenAI o3 - very slow
* Grok - is guessing Lisbon, Portugal (=wrong)

I believe if anyone showed us GPT4.5 10 years ago, we would call it AGI.

When I submitted my "Bullshit AI" talk to PyConAT, I had no idea Trump would end up giving me a perfect example. It is worth trillions of dollars. Literally.

Ondřej Svoboda má na LinkedInu pěkné ukázky, že 4o-image zvládne i české styly

Despite popular belief it is not true that current LLMs can solve math. olympiad problems.

(I have a set of Czech middle school problems Klokánek, most LLMs are slightly above random chance, best thinking at ~90%)

Draw me picture with two schemas explaining the difference between AlphaFold2 and ESMFold

My photo is attached. Try to add glasses to it (I am about to buy a new glasses and need to pick the style)

Draw me a little map of XYZ for my future visit. Not real map, just illustration. Include top places I should visit. Please, omit typical turist traps and concentrate on cheap free hipster punk things #gpt4o

If you have ChatGPT Plus (paid $20 version), try new image generation introduced yesterday. Seriously crazy.

This is me as Simpsons character (no special model, just prompt)

Test LLM šolynou. Hlubší než si myslíte. Většina thinking modelů to dá (ale ne DeepSeek-R1, ani QWEN)

Pár slov, co si myslím o DeepSeeku a dalších věcech, co teď hýbou světem umělé inteligence
