I haven't used zed specifically, but were you using your own API key for Claude? If so, you were probably running into the Anthropic API rate limits [1]. You can either a) deposit more funds to move your way up the tier list, or instead access Claude via something like OpenRouter, which will give you much higher limits.
Is there any sort of dynamic range compression available with Apple Podcasts? I've looked around, but can't seem to find anything. I find it especially necessary when listening in the car, so I've been using Overcast...
