I'll add another really positive review here. Sonnet 4.0 had been really struggling to implement an otel monitoring solution using grafana's lgtm stack. Sonnet 4.0 had 4 or 5 different attempts - some of them longer than 10 min - troubleshooting why metrics were supposedly being emitted from the api, but not showing up in Prometheus. Sonnet 4.5 correctly diagnosed and fixed the real issue within about 5 min. Not sure if that's the model being smarter, but I definitely saw the agent using some new approaches and seemingly managing it's context better.
