Here's what I've been working on nearly 3 years. This is a deterministic coding and refactoring engine. What coding should be, and the backbone AI needs to become provably safe. You can learn more about what it unlocks (and read things in dark mode) at evok.dev

This is what counts as codebase understanding today. A human having to write lossy vague instructions for an LLM trained to follow the least path of resistance. While this is definitely a way to do it today, it's fundamentally bro-science. You're depending on a series of

GPT5.4 is insanely good, really. This is the first model we've been deeply impressed by. It's excellent at staying on track in coding tasks that would otherwise lead other LLMs down regressive rabbit holes. Well done OpenAI Developers Greg Brockman Sam Altman
