Ask HN: Examples of O1 pro DeepResearch proving its worth?

Hey all! We use all the LLMs fairly heavily. We see their promise and are aware of their pitfalls. Wondering if DeepResearch really is a major step up compared to the rest or even our jerry-rigged prompt chains. If you've used it and have found a significant upside, can you please share your experience. An actual output would be wonderful. Thank you!
