On September 22, 2026, Hugging Face documented GGUF support in Transformers that reuses llama.cpp’s ggml Metal kernels via the kernels library—so Apple Silicon users can call from_pretrained on Hub GGUF files and generate with the standard Python API.
On September 15, 2026, Gensyn announced open-1b, a 1.61B-parameter Apache 2.0 language model shipped with per-step state hashes, intermediate checkpoints, training code, and a public audit client so third parties can replay training steps.
On September 17, 2026, Linkup Research released SPARSEUP, an Apache 2.0 ModernBERT-based sparse retriever on Hugging Face as Linkup-Platform/linkup-sparseup-embed-v1, positioned as a controlled companion to LightOn’s DenseOn and LateOn.
On September 16, 2026, Zhongguancun Academy and the Zhongguancun Institute of Artificial Intelligence published ZGCM-1-7B on Hugging Face under MIT, with arXiv technical report 2609.13356, training code, staged checkpoints, and a public data card.
In mid-September 2026, Knowledgator released GLiFormer under Apache 2.0—a shared-encoder framework for NER, classification, relations, nested JSON structuring, and embeddings—with Large v1 (575.6M) on Hugging Face and PyPI packages through 0.1.2 dated September 15.
On September 15, 2026, researchers announced ShadowPEFT as a first-class method in Hugging Face’s PEFT library—a stateful shadow-network adapter with the usual get_peft_model API, available now from PEFT main ahead of the next release.
Shanghai AI Laboratory’s InternLM org published Atria Dawn Preview on Hugging Face around September 11–12, 2026—MIT-licensed agentic MoE weights with an FP8 sibling, a 256K context listing on the model card, and vendor-reported agentic benchmarks, without a formal launch post.
DeepSeek released DeepSeek-V4.1-Flash on September 10, 2026 as a 552B MoE multimodal open-weight model under MIT, and starting 04:00 UTC on September 14 its API routes deepseek-v4-pro requests to Flash at Flash rates until V4.1-Pro ships.
Google Research’s ToolGrad framework builds verified tool-use chains before writing user queries, shipping Apache 2.0 code plus the ToolGrad-500 dataset and Gemma-3 fine-tunes that the authors report near frontier BFCL scores.
Cohere and Cohere Labs released North Small Translate on September 10, 2026—a 218B-parameter MoE translation model with about 25B active parameters—under CC BY-NC 4.0 on Hugging Face, with vendor-reported WMT26 scores led by an 83.6 all-languages figure.
Ant Group’s inclusionAI lab released Ling-3.0-flash-VL under MIT—a 124B MoE multimodal model with about 5.5B active parameters—with BF16 weights on September 4 and FP8 on September 8; BlockBeats framed the open-source release on September 9.
IBM released Granite Time Series PatchTST-FM-r2 on September 9, 2026—a ~385M-parameter zero-shot forecaster dual-licensed under Apache 2.0 and OpenMDW 1.0, ranked among top replicable zero-shot models on GIFT-Eval as of September 8.
Nex-AGI published Apache-2.0 weights for Nex-N2.5 Mini (~35B/~3B active multimodal) on Hugging Face September 8, 2026, with a 2×H100 SGLang recipe; Pro multimodal weights remain coming soon.
NVIDIA Personal AI Router (PAIR) is an Apache 2.0 virtual inference router that discovers home-network machines and spreads independent Ollama or LM Studio requests across them, cutting a five-subagent Hermes demo from 18 minutes to 8:48 on a three-device cluster.
NVIDIA opened CUDA Rust with two NVlabs projects—cuda-oxide for SIMT kernels and cutile-rs for Tile kernels—so Rust can compile natively to PTX and catch buffer aliasing at compile time, with cutile-rs already used in Hugging Face Grout and mistral.rs.
Thesys released OUI-1, a DiffusionGemma 26B-A4B finetune that writes openui-lang interfaces, scoring 71.7% on the Generative UI Benchmark versus 13.0% for the base model, under Gemma Terms of Use.
