Beating AI Express News reports that large language model (LLM) evaluation blogger "Cat Boss" discovered during testing of MiniMax M3.1 Flash that the model scores nearly full marks on old questions but almost zero on new ones. On average, the model consumes tens of thousands of tokens per question, though it only uses around 10,000 tokens to answer some difficult questions correctly. This anomalous performance has sparked suspicion that the model may have memorized answers to some questions in advance. Cat Boss maintains the private "Zhizhi" LLM leaderboard, using a non-disclosed test set focused on evaluating logic, math, and coding capabilities. The test set typically includes no more than 28 questions and 270 test cases, with partial questions updated monthly. Each question is tested three times, and both the highest and median scores are tracked. The median score for M3.1 Flash reached 51.76, more than double the previous generation M3's 23.86, and is close to DeepSeek V4.1 Flash 1017's 56.03. Some developers suspect the model was specifically trained on old questions rather than truly mastering problem-solving methods. This practice of optimizing models solely to improve evaluation scores is known as "Benchmaxxing".

China will firmly safeguard the legitimate rights and interests of Chinese enterprises. (Source: Beijing Daily)

JPMorgan Chase estimated on Tuesday that most global banks have limited exposure to CoreWeave (CRWV.O), the Nvidia-backed cloud computing firm, after its stock and bonds plummeted last week amid investor concerns over its debt financing. While major U.S. investment banks and Japan’s Mitsubishi UFJ Financial Group may hold potential exposure to CoreWeave of between $1 billion and $3 billion, most European and Asian lenders have exposure of less than $500 million. Most of this exposure comes via delayed-draw term loans, which are primarily held through special purpose entities, with funds disbursed upon the achievement of project milestones. From the lending banks’ perspective, JPMorgan views the sector’s exposure to CoreWeave as well-managed and backed by robust collateral.
