Seeing how much of their API revenue is coding, let’s hope they deliver.
I can’t wait to compare Claude 3.7 and Grok 3! :slightly_smiling_face:

Anyone else excited?

(*I unmarked as “solved” so we can discuss without the annoying message when replying to a “solved” topic.)

I’m seeing some issues when it tries to send text back to composer in agent mode. As well, it is timing out with anthropic at times and every time you say “resume” it counts it as another fast api call. Hopefully for those impacted cursor team will make it right. Using fast api calls at quite a clip with the resumes. And in this case i need 3.7 to solve something that 3.5 could not
