llama.cpp v0.6.0 ships GLM-5.3-Flash (320B) and Qwen4Exp MTP speculative decoding, a new llama_batch_ext API, and up to ~3x faster few-row mat-mul on Apple GPUs

ggml-org released llama.cpp v0.6.0 on Oct 5 (v0.5.0 was Sep 23). It brings GLM-5.3-Flash (GLM5-Next, a 320B text+vision hybrid MoE) into a stable tag, adds MTP speculative decoding for Qwen4Exp (~1.5x decode on DGX Spark), introduces the llama_batch_ext / llama_process() API for mixed token and embedding batches, adds few-row MMA mat-mul kernels on Metal (up to ~3x for speculative and batched decoding), and bumps ggml to v0.26.0. Session file formats are bumped too.

Key Takeaways

  • New models: GLM-5.3-Flash (GLM5-Next, 320B KDA/DSA hybrid text+vision MoE), Clef decision model, Ling 3.0 VL, LFM2.5-Encoder
  • Speed: Qwen4Exp MTP speculative decoding ~1.5x decode on DGX Spark; Metal few-row MMA mat-mul up to ~3x
  • API: llama_batch_ext + llama_process() for mixed token/embedding batches; server and examples migrated
  • Compat: LLAMA_SESSION_VERSION 11 and LLAMA_STATE_SEQ_VERSION 4, so old session/state files must be regenerated
  • Server: /v1/models reports modalities, /v1/embeddings takes typed vision/audio/video input, new /v1/systemone endpoint

Alibaba Qwen open-weights Qwen3.8-Flash: 125B/6B multimodal MoE scoring 62.5 on SWE-bench Pro

Alibaba Qwen released open-weight Qwen3.8-Flash, a multimodal Mixture-of-Experts model billed as an early preview of the Qwen4 architecture. The production-scale checkpoint is 125B parameters plus 51B N-gram embeddings, with only 6B activated per token. The new stack combines Gated DeltaNet plus Qwen Sparse Attention, Gated Residual branches, N-gram embeddings that can live in host memory, and a refined Muon optimizer. Qwen said it trained at about one-ninth the cost of Qwen3.7-Plus while beating it across the board, especially on coding and office work: 58.7 on DeepSWE 1.1, 62.5 on SWE-bench Pro, 73.9 on CoWorkBench, 84.5 on AndroidWorld, and 95.7 on MathVision with CI. Native context is 262K tokens, extendable to 1M with YaRN; at 1M context the QSA kernel is up to 7.6x faster in prefill and 4.9x faster in decode. QwenCloud lists roughly $0.15 input / $0.47 output per million tokens, and day-0 runtimes arrived from NVIDIA NeMo, SGLang, Unsloth, OpenRouter, and OpenCode Go.

Key Takeaways

  • 125B/6B MoE hits 62.5 SWE-bench Pro and 58.7 DeepSWE 1.1 at ~1/9 the training cost of Qwen3.7-Plus.
  • QSA hybrid attention is up to 7.6x faster in prefill and 4.9x in decode at 1M context.
  • Open weights plus day-0 support on QwenCloud, OpenRouter, OpenCode, NeMo, SGLang, and Unsloth.

Alibaba Qwen Open-Weights Qwen3.8-Flash: 125B MoE Previewing Qwen4 Architecture

Alibaba Qwen released Qwen3.8-Flash, an open-weights 125B MoE model (6B active) previewing the Qwen4 architecture with 1/9 training cost, 262K native context, and ultra-cheap API pricing.

Key Takeaways

  • New core architecture combining GDN gated residuals, sparse attention, N-gram embeddings, and Muon optimizer;
  • Coding & SWE benchmarks: 58.7 on DeepSWE 1.1, 62.5 on SWE-bench Pro, and 73.9 on CoWorkBench;
  • Day-0 support across QwenCloud, OpenRouter, vLLM, SGLang, and Unsloth (runnable locally with ~75GB RAM via GGUF).

Qwen3.8-Flash-Next Runs Locally on 75GB RAM with Day-0 Unsloth GGUFs

Alibaba Qwen confirmed that the 125B multimodal MoE Qwen3.8-Flash-Next can now run locally on about 75GB of RAM via Unsloth GGUFs, with N-gram embeddings offloaded to CPU or unified memory for near-VRAM speed. It is the day-0 local path for the Qwen4 architecture preview weights.

Key Takeaways

  • 125B MoE with 6B active parameters plus 51B n-gram embeddings now runs locally on ~75GB RAM without fitting the full model in GPU VRAM
  • Unsloth shipped day-0 GGUFs and a Qwen3.8-Flash-Next guide; CPU RAM / unified-memory setups approach VRAM throughput
  • Official weights remain on Hugging Face and ModelScope, with day-0 vLLM and SGLang serving on NVIDIA and AMD
