I'm a sailor who drifts between art and science, I am currently working on world simulators @ Lucid.

I'm a researcher working on generative models, mainly those that can simulate world dynamics (named world models), I'm also interested in what the next generation of generative models will look like, and how to scale them up.

Previously I worked on research in diffusion models with some brilliant friends. I also built a research chat over Twitter known to host very interesting chats, ml_chat. And prior to that I worked on software at several startups (including my own).

I like to surround myself with soulful people who inspire me to think deeper and never stop questioning. Check out my friends. I also like to read and indulge in the opinions of others, check out some of these posts that I like.

I am always cognizant of the fact that I missed out on many possible lives I could have had, and often contemplate what is the best way to increase the likelihood of arriving at the . People coin this “luck surface area”, for me it's more about the unexpected appreciation I have for things I didn't even know I cared for. Perhaps one day I will write about this.

    500miles on a bike, SFO -> LAX (opens in a new tab)

    Took a 500 mile bike ride from San Francisco to Los Angeles, I got a chance to explore the US and see some beautiful scenery.

    San Francisco 🇺🇸 (opens in a new tab)

    Moved to the US on O1 visa to get closer to the research community and build with more resources

    Exploring world models @ Lucid.ai

    Excited by the prospects of these models and how to scale them up, I started Lucid, got into YC W25, and raised ~$7m from YC and other investors

    Lucid V1 (opens in a new tab)

    Released Lucid V1 and it got incredible traction, got featured in major publications and was also used as a baseline by Dreamer V4, this also marked the beginning of my journey into the world of world models.

    Research on diffusion models

    Worked on several research projects with some friends, published https://arxiv.org/abs/2412.02352, and started working on video models, unfortunately the project didn't pan out because of NDAs, I pivoted to constraining models to simple environments to focus on the world modelling aspect.

    Made wandview & ml chat

    In need of a way to visualize my weights and biases projects I built a mobile app that allows me to do just that, it became incredibly viral and got me a lot of attention (4,000+ researchers used it!), this also led me to start mlchat to learn more about research, it was often referred to as the most productive thing on Twitter.

    Left my startup

    The company was severely focused on business dealings and not technical work, so I decided to leave and start working at Toptal as a software engineer that briefly introduced me to ML again on one of my projects

    Cofounded telecom startup

    Helped resolve a major bug with .et TLD that caught the attention of the CTO of the largest telecom company in ethiopia, excited by the prospect of building native solutions (current systems are imported from abroad) I started a company, At 18 I won several government telecom contracts that were valued at M$+.

    Fun fact, My company helped launch spotify in Ethiopia :)
  10. Jan 2019 — Dec 2021

    360Ground

    Started helping them with Google natural machine translation models and ended up taking several roles including design and development, I ended up becoming the CTO/Tech lead briefly after the existing CTO was poached by microsoft, there, I worked on one of the largest apps in ethiopia at the time...

    Dropped out of junior high school to pursue my love for building things, interned at iCog Labs (known for Sophia realistic humanoid)

    I've always learned through experiments and association, building intuitions before formalising them. School wanted the opposite: absorb the conclusion, then move on. That mismatch meant I was always doing twice the work to arrive at the same place my peers started from. Early in high school, I realised I'd learn faster outside of it. The only robotics lab in my city took me in, and that was reason enough to drop out.
  12. ~ 2014

    Started coding at 11 years old

    Built a website for my school to help them manage assignments and attendance, it was perhaps the first time i felt like I was doing something meaningful

You're already in the past.

A surprising portion of what I do has become interpreting the world and managing long-term projects for which no verifier exists, and even if one did, the rewards would be uneconomical to compute.

On change

Quite often, I feel like I arrive at beautiful things when they’re in the second half of the show.
