I don’t love it for summarization. If I read a summary, my takeaway may be inaccurate.

Brainstorming is incredible. And revision suggestions. And drafting tedious responses, reformatting, parsing.

In all cases, nothing gets attributed to me unless I read every word and am in a position to verify the output. And I internalize nothing directly, besides philosophy or something. Sure can be an amazing starting point especially compared to a blank page.

It's good for coding if you train it on your own code base. Not great for writing very complex code since the models tend to hallucinate, but it's great for common patterns, and straightforward questions specific to your code base that can be answered based on existing code (eg "how do I load a user's most recent order given their email address?")

the model seems ok for tasks like summarisation though

That and retrieval and the business use cases so far, but even then only if the results can be wrong somewhat frequently.
