Ben Hylak posted that the Codex app has gotten consistently worse every single day for the last month. The Raindrop AI co-founder and CTO, who previously worked in design at Apple and engineering at SpaceX, called the changes disappointing and said it was sad to see OpenAI do this to the best product they ever made. The statement is his own assessment from the public post and attributes the decline directly to OpenAI. No other details on specific changes or external confirmation appear in the evidence.
