LLAMA.CPP SHIPS MINIMAX-M3 SPARSE ATTENTION, VLLM UNLOCKS HETEROGENEOUS PREFILL-DECODE

By RepoJournal · Filed · About Local LLMs

The inference stack gets a new model architecture and a fundamental shift in how prefill and decode can run on different hardware configurations.

Llama.cpp landed full MiniMax-M3 support [2] [4] with vision tower integration, adding sparse attention capability to handle 60-layer, 128-expert MoE models where "a lightweight per-GQA-group indexer scores the visible causal context, max-pools the scores into 128-token key blocks, and selects the top-16 blocks" [6]. The model joins an expanding list of specialized architectures getting native dispatch. On the vLLM side, MoRIIO heterogeneous prefill-decode routing [7] is now live, enabling prefill and decode phases to run different parallelism strategies (TP vs DP+DP) on the same cluster, yielding measurably higher throughput and lower TTFT at scale on MI300X. SGLang shipped LoRA support under breakable CUDA graphs [8], restoring prefill graph acceleration to LoRA workloads, and added EmbeddingGemma [9] with bidirectional attention and mean pooling. Meanwhile, llama.cpp fixed critical routing bugs for model names with slashes [5], resolved iOS conversation import by detecting format from file contents [3], and Ollama pushed an mlx update [1]. This period saw 60 commits and 60 PRs across 4 core repos, with 5 releases shipping.
