New context in the MRCR benchmaxing debate: Google MRCR author Kiran Vodrahalli says MRCR isn't about needle retrieval — it measures a model's understanding of ordering, one of many dimensions of long-context understanding that's just hard to ace. eliebakouch rounds up the MRCR author's tweet and Anthropic's statement as the best recap, conceding that long-context, like any capability, can be benchmaxed in some directions while remaining important — but using MRCR alone as a proxy is misleading.
