I have also had some super weird stuff in my output (2.5-flash).

I'm passing docs for bulk inference via Vertex, and a small number of returned results will include gibberish in Japanese.

I had this last night from flash lite! My results were interspersed with random snippets of legible, non-gibberish English language. It was like my results had got jumbled with somenone else's.

I’ve gotten Arabic randomly in Claude Code. Programming is becoming more and more like magic.

I get this a lot too, have made most of the Gemini models essentially unusable for agent-esque tasks. I tested with 2.5 pro and it still sometimes devolved into random gibberish pretty frequently.
