    I'm Varun, CEO of Exafunction, and we just released Codeium to open up access of generative AI to all developers for free.

We have built scalable, low-latency ML infra for many top AI companies in the past, and we are excited to leverage that tech into a product that we, as developers, would love. We hope that you do too, and we would appreciate any feedback that this community has for us!
