Tencent Hunyuan released Hy-Memory-30B-A3B, a 30B-parameter mixture-of-experts model with about 3B active parameters, built to run the write path in external memory frameworks. Tencent reports a 55.49 cross-harness average, ahead of Claude Opus 5 (54.62) and DeepSeek V4.1 Flash (53.64) on its own fixed 20% benchmark subsamples.

AI memory systems that help models adapt to users can make them less accurate, according to two papers published by Writer. As user preferences fill the context window, models become more likely to agree with misconceptions rather than provide correct answers.
