Hey everyone! I have a 2.5-hour video transcript that I need to turn into detailed notes. I've tried Gemini 2.5 Pro and found it decent, but I'm curious if models like "o3" or "o4-mini high" (or perhaps others) would perform significantly better for this task. Overall, what's the most powerful model out there for textual analysis? Cost isn't an issue, so I'm open to suggestions. Thanks!

In my experience, Google’s NotebookLM works wonders for summarizing long transcripts in detail. Other models like ChatGPT can sometimes leave out important parts or even hallucinate, especially with lengthy conversations. So I’d recommend giving NotebookLM a shot for your notes!
I typically use ChatGPT 4o and MS Copilot for analyzing transcripts, especially from technical calls that are 30-90 minutes long. I focus on extracting key points, actions, and risks, plus I look for any stress or confidence indicators in the language used by attendees. It’s really effective, just make sure to tweak your prompts for best results.
How do you get your transcripts? I’m using the basic Teams recording feature, but I often end up spending too much time fixing the speaker IDs!
