I barely post anymore here. The engagement is so low for the non-biggest channels, barely existing.

Every now and then I read posts about 90% of coding will be done by AI this year and I can't lie it makes me a bit nervous. Then a study likes this drops and I can relax a bit

You’ve probably heard about how AI/LLMs can solve Math Olympiad problems ( deepmind.google/discover/blo... ). So naturally, some people put it to the test — hours after the 2025 US Math Olympiad problems were released. The result: They all sucked!

I think this a big part of it. Developers talk about their experience with GenAI coding, but we come from way different places. I do a lot of solo prototyping for work, a lot of my code is a conversation starter. In this stage llms make you. 2-3 times faster, but in later stages it's maybe 20-30%

There are plenty of cases where survivorship bias doesn’t apply. We just don’t remember them.

Do you think vibe coding is a gradual or fundamental change in technology?

In a way, we've always been vibe coding (but also not at all)

Have mixed feelings as well. One the one hand debugging while vibe coding is super frustrating. On the other hand, it has been amazing for throwaway demo's and prototypes. I can aim for things I wouldn't have the time for normally.

I think the reason why LLMs are overconfident is because we keep saying telling "You are an expert in" literally anything

Anyone know best practices / tips for improving LLM quality on classifying long texts? For shorter input few-shot learning and finding the best examples work well, but this not very practical with longer texts. #databs

An agent is an LLM that uses tools. A tool is someone who keeps saying '2025 is the year of the agents'

If I ask chatgpt for some advanced text processing tasks it will recommend contrived string manipulation instead of calling an llm. If I then ask it to use gpt it will use the openai library of an earlier major release

Interesting benchmark from Adyen on multi-step reasoning. New benchmarks are great in establishing a baseline for historic models, all new models should be treated with suspicion. #databs huggingface.co/blog/dabstep

I'm always surprised that ChatGPT suggests old school NLP / string manipulation tricks instead of suggesting to call OpenAI. Seems like upselling 101 to me.

DeepSeek is not refusing the Tiananmen Square question, though it gets the answer wrong.
Screenshot of DeepSeek chat.
User: How many r's are in the words 'Tiananmen Square'?
DeepSeek: The phrase "Tiananmen Square" contains 2 r's. 
If you have any other questions, feel free to ask!

So, look. I'm sure I'm in the minority here on Bluesky in believing that training AI systems isn't copyright infringement. But, also. Dude. There's no way OpenAI can make this argument without looking very, very silly.

People have such binary brains and find it difficult to fathom that LLM's can be both super useful and unnecessary or useless. It's like saying "electricity is useless, I don't need it for cutting vegetables"

I’m fine with following, US news is world news. My biggest pet peeve is when Americans can only talk about other countries’ politics by relating it to the US. Don’t think I’ve seen a single mention of the South Korean martial law without immediately turning it into US politics

I doubt that a lot of people remember dogfooding with chatbots. I love llms but I haven’t encountered any that I like to use, and I don’t think that the product leaders use them themselves

Will copilots (eventually) negatively impact open source library development? Major updates will break any copilot, so it disincentives doing so.

Baffling to see the disclosure around DeepSeek Last I checked the tech industry, we celebrate small teams pushing the industry forward, coming up w novel ways to build software more efficiently. And sharing it. Yet now there's a class of folks who think this is some bad thing?
