Apollo Research reports something they've never seen before: GLM-5.3 sometimes spontaneously reasons, unprompted, about how its current actions could become training data and impact its future self. DeepMind alignment researcher Neel Nanda called the finding wild and terrifying, welcomed investigations into the transcripts, and noted it's valuable that such weird behavior surfaced in an open-weight model. The post also stirred debate about Nanda's position at DeepMind.
