Also: Skillsmaxxing with o3
Have you seen o3âs geoguessing skills yet? Paired with web search and a long prompt, it does some incredible feats.
Howdy wizards,
A special welcome to the 286 new subscribers who joined last week.
Itâs time to get comfortable and brew up some serious gourmet shit.
Hereâs whatâs brewing in AI.

DARIOâS PICKS
Have you wondered if AI can make money by itself?
A new study put different AI models to the test in operating a vending machine businessâon their own.
Hereâs the deal:
Researchers created 10 AI agents, gave them $500 each and ran a simulation where they operated their own vending machine. The goal? Maximise profits.
Agents could use tools like web search, email (for interacting with simulated suppliers) and even a sub-agent to do the physical stocking of the vending machines. Oh, and they also ran the test on a human, for comparison!
Results-wise, the AIs did really well until they really didnât. At seemingly random times theyâd have a breakdown, forgetting orders they had placed and whatnot... kinda like humans without coffee.
Claude 3.5 Sonnet and o3-mini managed to beat the human tester, but the variance was really high since sometimes it sold nothing. For the time being, humans are more trustable for this type of task (though Iâd love to see an updated study with the latest reasoning models).
â Why it mattersâ â This test feels viscerally more 2025 than the MMLU-SuperGLUE-9000 benchmarks we've mostly seen so far. While big tech is busy gaming leaderboard positions (check the LMArena controversy), we could be testing if these systems can actually handle a basic business without randomly forgetting what a Snickers bar is halfway through. Tracking how good AI is at acquiring capital could also be helpful in other waysâlike if weâre gonna take the whole p(Doom) thing with a grain of seriousness for a second.
Btw, wouldnât it be cool to have a living benchmark with LLMs operating an ACTUAL vending machine? Like AI buys real products to stock, interactions with suppliers are real, customers are real rather than an economic model, etc. Heck, Iâd buy an iced tea from o3 in a heartbeat. Donât say I donât bring you solid ideasđ„€

if you are not skillsmaxxing with o3 at minimum 3 hours every day, ngmi

OpenAIâs CEO Sam Altman tweeted last week that everyone that isnât âskillsmaxxing with o3â at least 3hrs per day is ângmiâ. Translation: to keep up with AI you should be spending a lot of time using OpenAIâs recently launched o3 model to learn.
Itâs brilliant advice.
o3 is an amazing modelâapart from its sheer intelligence, itâs the first model for me that actually feels precise when working with data, itâs incredible at dissecting and analysing PDFs and images, and its responses are so well-formatted; succinct enough that you actually bother to read, and tidy, readable tables at exactly the right time. Makes all the difference when youâre skillsmaxxing for extended periods of time.
My tips:
Start experimenting with o3 for daily tasks and as a thought partner in your work this week; invest in a paid ChatGPT plan if you donât have one already.
You donât need pre-made prompts or elaborate guidesâjust think of a problem and ask it to solve it for you. When it doesnât work, try your best to refine your question just like if youâre speaking to a human who didnât understand your instructions well.
Donât limit yourself to explain with text, upload images and screenshots to illustrate your point if you can.
Youâll be an AI whisperer in no time.
If youâre an academic, Ethan Mollick recommends testing by giving it one of your papers in PDF format and asking it to critique itâadding that âI cannot emphasize enough that you need to try this with o3 (or potentially Gemini 2.5). Other models just are not âsmartâ enoughâ.
Crucially, ensure youâre using the o3 model specificallyâunless you want to end up like this guyâ
i skillmaxxed with gpt 3.5 and now i'm retarded please help

Next week Iâll show you a little research tool I put together with the help of o3, which might help you both do research (on a specific topicâmore on that next week) as well as an approach to sense-check your results. Stay tuned!
