grok 4.5 managed to debug and fix and issue that caused an incident for my project yesterday. I ran a multiagent debugging session first with grok 4.5 high, then it found the root cause and implemented a small fix in k8s manifests, deployed and verified the fix, all in under 30 minutes. the day before it took me 3+ hours of debugging and poking around in several sonnet 5 medium sessions to at least figure out what was going on - and I didn't. in terms of context usage, grok used ~115.9K for the whole session.
