    Why we won't be replaced by AI There’s been a lot of talk about AIs replacing programmers recently. The National Post: “AI is coming after the tech bros and their easy money”. Emad Mostaque, CEO of Stability AI: “There Will Be No Programmers in Five Years”. Some people are

    Five years ago I created TabNine, the first commercial code completion tool to use deep learning. Today I'm releasing Supermaven, the first code completion tool with a context window exceeding 100,000 tokens.

    Time to share what I've been working on for the past couple months: a visual search engine called Same Energy. It's early stages but you can try the beta here: same.energy

    I've decided to leave OpenAI to work full-time on creating a visual search engine. I'll miss my coworkers but I'm very excited about what I'm going to make.

    So excited to be working with @jbfja and the Supermaven team! There are only two companies in the world that have shipped models with 1M+ token windows: Google Deepmind and Supermaven.

    I made a Twitter search engine. Instead of searching by keywords, you enter a tweet and it finds tweets with a similar "feel". Try it out: same.energy

    When using LLMs for code completion, you want the model to produce a completion that starts with what the user typed. But LLMs can only condition on sequences of tokens, not sequences of characters...

    Supermaven not only provides the best completions of any tool but it's also the fastest. In the video below I test the speed of Supermaven compared to several alternatives. Supermaven's response time is 250ms, over 3x faster than any other tool in this case.

    Many people asked if Supermaven trains on your code. To be clear: Supermaven does not train on your code. In the future we might let you get Supermaven at a discount if you allow training on your code. That will always be a clear opt-in: you won't end up there by accident.

    Unlike existing tools which are all based on the Transformer architecture, Supermaven uses a new operation which is better than self-attention at integrating information across a long context.

    There’s a length limit of 400 KB currently. We’re going to raise the length limit or at least add better communication about it. Thanks for giving it a try
