Patel reports kernel programmers use Codex to create code first, then have Opus rewrite for quality.
“I think it was tree down. Tree down is like, yeah, dude, Codex is like so dumb, but I always just have it created and then this and it works and it's smarter, but the code is sloppy, I have Opus rewrite it.”
Patel argues Mythos fast mode is probably cheaper than Claude 4.6 fast mode for most tasks due to token efficiency.
“the flip side is, is, is mythos is more token efficient. Methos fast mode is probably cheaper than like, four, six fast mode for most tasks.”
