Lead Story

llama.cpp v0.5.0 GA — Metal MoE fusion, multi-bind, pin-able release

On Sep 23 (~4:50 PM ET), ggml shipped numbered GA v0.5.0 — Metal MoE + SSM_CONV fusion, multi-address HTTP bind, ggml 0.25.0, and broader convert coverage after Issue 23’s tip-only lane.

Release highlights: CUDA conv2d implicit GEMM; Metal MoE and SSM_CONV fusion (#28948); server bind to multiple addresses (#28690); input_image on function-call outputs; HRM-Text / MiMo-V2.6 / HunyuanOCR conversion support; router lifecycle fixes; cpp-httplib 0.57.1. Nightly note on the GA page: build b11146.

Why it matters: operators finally get a pin-able GA (not only nightlies) with Apple Silicon Metal MoE fusion and multi-bind for llama-server — prefer v0.5.0 unless you need tip-only features (tip now b11158).

Industry Shorts

Critical · vLLM ≤0.29.x still exposed

Sep 23 Moderate GHSAs (structured-output EngineCore kill, GLMGA video DoS, Rust Prometheus cardinality, Qwen2/3-VL max_frames) stack on Issue 23’s Sep 22 NIXL/Mooncake batch. Land on ≥ 0.30.0; do not leave multimodal / Rust frontend / structured-output tenants on ≤0.29.x.

Watch · pin v0.5.0 vs tip b11158 · Bedrock connectors

Prefer llama.cpp v0.5.0 for pin-able installs; tip b11158 (Vulkan Adreno) / b11156 (Ling 3.0 VL) are nightlies. Bedrock Salesforce/Zendesk connectors need credentials and incremental-sync review before production RAG cutover.

Opportunity · Omni Cursor ext · Antigravity local · Gemini TTS

Install CloudWatch Omni’s free Cursor/VS Code extension for local agent instrument/eval. Smoke Antigravity LiteRT Gemma 4 26B or Ollama-compatible local backends. Wire Gemini 3.8 Flash TTS / Flash-Lite for voice agents. Optional one-liners: Unity Catalog Pages (Sep 22 companion to Genie One); Amazon Connect Customer A2A (Sep 22).
