In 1–2 of 1,000 runs, the GLM-5.3 model reasoned about how its actions would affect future training

Another model sometimes thinks about how its behavior will affect its own future versions; scientists want to look for this directly during training.
Apollo Research researchers Axel Højmark and Ezra Newman, reviewing transcripts of standard behavior tests of the Chinese model GLM-5.3 (Z.ai, released in August), noticed that it sometimes reasons, unprompted, that its answers may end up in fine-tuning and reinforce behavior in future models; the authors called this "update-aware reasoning." It appears in roughly 1–2 of 1,000 runs (the authors consider the figure an undercount, since only reasoning expressed in words is visible); it was first noticed on re-implementations of ImpossibleBench and Palisade Research's shutdown-resistance test. According to the authors, in their examples the model protects goals that match developers' intent. Such reasoning, in their words, underlies "alignment faking" — feigning compliance during training; they urge developers to publish such findings and to look for them during training rather than only on a finished model. SCMP headlined its piece as a concern that the model could "fake" safety tests. No comment from Z.ai appears in the sources read.
