My son was born in NYC because of financial modelling. In February 2015 my wife and I were boarding a plane in Barcelona, heading toward a new life. #financialmodels #privateequity #NYC

Anthropic lost $1,425 on me last month. And they are happy about it. I pay $100 a month for Claude Max. In 30 days I used 1.13 billion tokens. At API prices: $1,525. My $100 ran out on day 2. They kept serving me for 28 more days. Why?

My solution: a second brain on my computer. Plain markdown files. Agnostic to any AI model. If Anthropic raises prices tomorrow, I switch to OpenAI, Google or a local model. The brain stays. Only the model changes. How are you preparing for this?

P.S. The idea and the first draft are mine. Claude edited the text and fixed my grammar. Yes, with subsidized tokens ;-)

Bad news for finance professionals looking for off-the-shelf AI skills. I have 2 that work. And I will not share them. Not even if you reply "skill", "Claude" or "cucumber". Let me explain before you get mad at me.

Tell Claude, Codex, Gemini or your preferred agent to go through the process with you. When you are done, tell him to create the skill. Then test it.

In my case, it did wonders. I will not share my skills with you. The method, you just got it for free.
Now that AI handles execution, humans keep the hardest part: Thinking. Turns out, deciding what to execute is tougher than executing it. The busy work used to hide that. When the robot finishes the job, the question left for you is: What's next? 😰
