Same happened to me!! This is crazy, I’m so grateful with OpenAI, they gave me gpt3 access some weeks ago after long months of waiting, but suddenly they gave me access to Codex in less than 24hrs after the demo!!! And now they will send the T-shirt despite I finish #642 in the challenge!!
This is soooo crazy! Thanks very much to the team at OpenAI, you are giving me lots of opportunities to grow into a great developer
