OpenAI co-founder Greg Brockman retweeted Sam Altman's tweet and said, "After learning the news today, I sent the following message to the OpenAI team." The message is as follows:

I am very proud of what we have built together since we started in my apartment eight years ago. We have gone through difficult and great moments together, accomplished so much, even though everything seemed impossible to complete.
