New research

Inference efficiency dominates, with up to 2.5× gains in decoding and quantisation

Seven of eight kept papers target inference efficiency. KAIST and Google DeepMind's Large Flow Language Models reported 2.5× on an 8B model, Hong Kong PolyU's BitMTP reported 2.2×, and Tsinghua and Zhipu's E8-QAT reported 2-bit training on a 35B model with 1.97× decoding throughput; only three papers released code. An energy audit from the University of California and NVIDIA reported +3.73% accuracy in predicting joules per token.
