Deep Search and Think are good for coming up with answers.

If you want to copy and paste in Obsidian, you'll need markdown!

Be sure to disable Deep Search and Think and give this prompt after an answer you want to save to Obsidian:

Please provide the answer in plain text with Markdown formatting (e.g., ### for headings, - for lists, | for tables, text (url) for links), ready to be copied and pasted into Obsidian.

I've also used the following prompt after an answer:

can you reformat this response in markdown for Obsidian? I'd like to copy it and paste it as plain text (with markup for formatting).

grok should give you a code section that you can copy in the upper left hand corner.
