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.

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.

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.

This allows us to expand the context window to 300,000 tokens (30 times longer than any other tool) while keeping cost and latency low. As a user, that means Supermaven will understand APIs and conventions that are unique to your codebase.

Supermaven sees not just your code but also the sequence of edits you've made since your previous commit. That helps it understand your intention when you're making changes.

You can start using Supermaven today. Follow the link in my bio or go to the @SupermavenAI account to try it.

just signed up. works well. you da boss

Any chance on getting a webstorm plugin?

Yes - next week

Reporting back in after using it. One awesome thing that isn't even mentioned is it's WAY smarter about cleaning up the line if it's doing a completion mid-line. With copilot there's almost always leftover jank I have to clean up. With Supermaven I can hit tab and move on.

Congrats on the launch! I was an early user of TabNine back in 2018 and I'm stoked to see this. IntelliJ support soon?

Yes, hopefully next week
