Lex Fridman
AI researcher · Lex Fridman Podcast
AI researcher and host of the Lex Fridman Podcast, known for very long conversations with scientists, builders and writers. His personal routine is famously austere: fasting, daily jiu-jitsu, long deep work blocks and a lot of Dostoevsky. He talks about the routine openly as a way of managing his own mind.

Claude
Splits his programming roughly half and half between Claude Code and Cursor. One reason he gives for Claude Code is building the skill of programming in English, guiding the work at a macro level instead of checking every diff.

Adobe Premiere Pro
Calls himself a Linux person who stays on Windows anyway, because of Premiere and the rest of Adobe. For a long time that meant running Linux inside Windows through WSL, which he says is not the good kind of Linux.

Gemini
Gemini is the interface he prefers, though he allows that this might just be momentum. Its retrieval over long context won him over, so he reaches for it when a prompt carries a lot of material and every part of it has to be tracked.

Grok
Keeps Grok for hard debugging. When the other models cannot crack something, he says Grok 4 Heavy is the best at it.

Perplexity
He is a keyboard person, and the shortcut he points to is Ctrl-I, which opens a new thread and, he says, speeds him up a lot. He also calls the decision to show that shortcut in the desktop interface a gutsy one. Perplexity sponsors his show.

BIAS FX
Asked by Rick Beato what amp he plays guitar through, he owned up to an amp sim, BIAS FX, and apologized for it.

Cursor
The other half of that coding time sits in Cursor, where he can watch the diff as the model works. He also says he uses its Composer model a lot, mainly because it is fast.

ElevenLabs
For dictation he puts the raw audio through ElevenLabs, which he calls probably the best speech-to-text model. Mistakes still come back, so the text then goes to a prompt holding a dictionary of names and terms he uses often.

Portable podcast kit
Records with a little suitcase of basic consumer equipment and one light. An acoustics expert once looked at his room and told him everything he was doing was wrong, and what he took from that was that he does not need experts.

“For me, I start the day. Actually, that’s why I’m afraid, I’d really prize those morning hours. I start with the work, and I’m trying to hit the four-hour mark of deep focus.”
