An attempt to explain (current) ChatGPT versions. I still run into many, many people who don't know that: - o3 is the obvious best thing for important/hard things. It is a reasoning model that is much stronger than 4o and if you are using ChatGPT professionally and not using o3 you're ngmi. - 4o is different from o4. Yes I know lol. 4o is a good "daily driver" for many easy-medium questions. o4 is only available as mini for now, and is not as good as o3, and I'm not super sure why it's out right now. Example basic "router" in my own personal use: - Any simple query (e.g. "what foods are high in fiber"?) => 4o (about ~40% of my use) - Any hard/important enough query where I am willing to wait a bit (e.g. "help me understand this tax thing...") => o3 (about ~40% of my use) - I am vibe coding (e.g. "change this code so that...") => 4.1 (about ~10% of my use) - I want to deeply understand one topic - I want GPT to go off for 10 minutes, look at many, many links and summarize a topic for me. (e.g. "help me understand the rise and fall of Luminar"). => Deep Research (about ~10% of my use). Note that Deep Research is not a model version to be picked from the model picker (!!!), it is a toggle inside the Tools. Under the hood it is based on o3, but I believe is not fully equivalent of just asking o3 the same query, but I am not sure. All of this is only within the ChatGPT universe of models. In practice my use is more complicated because I like to bounce between all of ChatGPT, Claude, Gemini, Grok and Perplexity depending on the task and out of research interest.

@anthonykasza @Centurion @chort0 Hi all. Search for "bulletproof registrars", "bulletproof hosting" or replace "bulletproof" by the term "rogue". You'll find enough literature to understand the ecosystem. Let me know if you have questions.

Pleading a bit of ignorance here, but it seems to me like registrars should be a more proactive provider of threat intelligence. For example, questions I often think about are: - Do certain threat actor groups prefer or exclusively use certain registrars?

Sean Connery was a legend, one of the greatest actors of all time. He provided endless entertainment for all of us & inspiration for me. I’m not just saying that because he was a bodybuilder who placed in the Mr. Universe contest! He was an icon. My thoughts are with his family.

Exactly 51 years ago, we were on our way to the Moon! There was a sense of excitement, focus, purpose and anticipation. America was on the verge of completing the “impossible.”

@davidu Watched it last year. Visually it's very slick. Story may be confusing but the music and vibe is what I enjoyed the most and what kept me interested. Brings back the cyberpunk, synthwave tones and some cool 1980s nostalgia.

A bunch of people told me to watch Altered Carbon on Netflix. I’m three episodes in and so confused. I’m not sure I understand the plot, or really anything about what’s happening. I’m hardly multitasking while watching. Do people understand this show?
