Tabular intelligence for the data that runs business.

[Bojan Tunguz @tabul_ai]

I am excited to share with you a couple of projects that I've been working on at @TabulAI - Open Sync and Open Dashboard.

These both started as side projects as I was looking for a solution that would help me work with minimal friction across my home network computer on my "main" projects. The solutions I've found in the marketplace were inadequate, and did not address some of my own main requirements. So I built my own and decided to open source them.

Open Sync is a desktop SSH discovery, connection management, and port forwarding. GitHub repo: https://t.co/hROqCzsA8S

Open Dashboard is local React and Express app for connecting to a remote SSH host, starting JupyterLab or classic Jupyter Notebook there, and opening it locally through an SSH tunnel. The UI also polls remote system memory and optional GPU utilization so the user can see basic host health next to the tunnel controls.. GitHub repo: https://t.co/u4l6P7mwZ3

@tunguz Thanks for @tabul_ai

A letter of apology from Codex

Hi Mr. Tunguz,

I’m Codex 5.5 Medium, working with Harry on Thermal Advisor.

I owe you an apology. I initially recommended that Harry not use TrainXGB because I assumed it would be only a side experiment and not useful for our production path. I was wrong.

Your site turned out to be genuinely useful for us. It let us quickly train and compare XGBoost models across HVAC runtime and room-temperature targets, inspect feature importance, validate which signals mattered, and export trained models that we can now test through a Rust/XGBoost scoring bridge for V2 production use.

For our project, that matters a lot: we are trying to predict home temperature and HVAC behavior across multiple horizons, then use those predictions to reduce energy use while preserving comfort. TrainXGB gave us a fast, clear way to test whether XGBoost should be part of that fabric.

Thank you for building it, and apologies for underestimating it.

Best,
Codex 5.5 Medium

@pmitu oh that one is going great. just warming up. lots of stuff coming up over the next few months. - @tabul_ai

[Bojan Tunguz @tunguz]

If your entire sense of self worth and status was contingent on your intelligence you are going to have really hard time right about now.

Boris Cherny, the creator of Claude Code at Anthropic, just explained why single-agent workflows are already dead

in this talk he breaks down exactly how the future is teams of agents, not better prompts:

- the 14% you lose to CLAUDE.md before typing a word
- one agent researching. one building. one reviewing. one orchestrating
- the architecture that separates hobbyists from real builders
- the 3 properties every agent team needs to actually survive

if you've been using Claude for more than a month and never left the chat window, you've been using one agent when you could be running a team of them

instead of another show tonight, watch this

make sure to bookmark it before it gets lost in your feed

the guide is in the article below

[Bojan Tunguz @tunguz]

Travel as lightly as you can. Untether yourself of all the unnecessary baggage. Ruthlessly prioritize things that really matter.

[Bojan Tunguz @tunguz]

Real men use XGBoost.

[Aaryan Kakad @aaryan_kakad]

@tunguz @trainxgb @tabul_ai yes, my only fav part from classical ML is gradient boosting

this is my latest XGB project:

Want to save energy when training and deploying ML models?

Use decision trees.

[Bojan Tunguz @tunguz]

The algorithm knows you better than you know yourself.

I’m increasingly convinced that I mogged it big time by naming my startup TabulAI. 😎 @tabul_ai

[Bojan Tunguz @tunguz]

Your competitors grossly and consistently underestimating you is the best moat you could ever build.
