Had the same wave yesterday. Here's what's going on from what I've pieced together: 'AI hiccup - retrying' means the response stream stalls mid-generation and the editor retries automatically. Not your connection, usually not your prompt either. It gets worse with long answers and busy servers, which fits everyone getting it at once. What helps me: one task per message instead of big multi-part requests, and if it hiccups twice in a row I start a fresh chat. Long sessions pile up context and get slower and dumber - that probably explains the 'overthinking simple tasks' part too. AC-0009 with a fine connection is a false alarm on the client side, your message is saved, just retry. On images: I've seen the helper fail to 'see' uploads that went through fine. The file saves correctly but the pixels never reach the model, so re-uploading rarely helps - describe the image in text instead and keep going. Reporting the exact codes like this is genuinely useful, thanks.
