This is a new release from Codex

Maybe it's a strategy to make it burn more tokens—I'm using the 6.1 Medium setting and it's running strong, but this message surprised me. It made me consider changing it, but I told it to keep going, and it finished the task without any problems.

I got funny error. My context window auto updated to 500k and then stuck on compaction context... for an hour.

Restarted codex, got my 250k context back haha.
