NVIDIA HAS AGREED TO ACQUIRE HUGGING FACE FOR $12,930,300,000 (announced 2026-09-03 by Jensen Huang on NVIDIA's own blog, confirmed the same day by Hugging Face on its homepage) -- THE OWNER OF NEMOTRON NOW ALSO OWNS THE HUB NEMOTRON IS DISTRIBUTED ON. This is the most consequential corporate fact in the open-weights ecosystem this year, and it is stated first-party by both sides, so it is not rumour: NVIDIA's post is by-lined Jensen Huang and gives an exact figure, and huggingface.co carries a banner reading 'We are happy to share our intention to join forces with **NVIDIA**' linking to it. **SCALE OF WHAT IS BEING BOUGHT, PER NVIDIA:** more than **18 million developers, researchers and creators**, more than **3 million models, 500,000 datasets and 1 million applications**, and more than **200,000 companies** using the platform. **THE COMMITMENTS NVIDIA MADE IN WRITING, WHICH ARE THE PART THAT MATTERS TO ANYONE RELYING ON THE HUB:** 'Hugging Face will remain an open platform for the entire AI ecosystem'; developers 'will choose the models they want, the frameworks they want, the clouds and inference service providers they want and the computing platforms they want'; and, explicitly, **'NVIDIA compute will not be required to build on or deploy through Hugging Face'**, with continued support for **multi-cloud and multi-accelerator development and deployment** and for open models 'from every model builder'. **NVIDIA'S STATED STANDING IN THE ECOSYSTEM:** it calls itself 'the largest contributor of open models and data to Hugging Face', citing **more than 500 models and more than 250 open datasets** released there -- Nemotron among them. **READ THE CONFLICT OF INTEREST HONESTLY RATHER THAN EITHER DISMISSING IT OR OVERSTATING IT.** The neutrality commitments above are unusually specific and were made unprompted, which is meaningful. But the structural fact is unchanged: the company that sells the accelerators, and that publishes Nemotron in competition with every other open-weights family on the hub, now controls the **default distribution and discovery surface** for all of them -- including model cards, search ranking and the download path. None of the commitments are time-bound or externally enforceable. **WHAT IS NOT KNOWN, AND DO NOT LET AN AGGREGATOR FILL IT IN:** NVIDIA's post is an intention-to-acquire announcement and contains **no closing date, no regulatory-approval language and no customary-conditions clause**. The deal is agreed, not closed. Treat any reported completion date as unsourced until NVIDIA or Hugging Face says so

NEMOTRON 3 ULTRA SHIPPED (2026-06-04, announced at Computex 6/1): the family flagship is live -- 550B total / 55B active hybrid Mamba-Transformer MoE, NVFP4 precision, Nvidia claims ~5x throughput vs comparable open models and ~30% lower cost on long-running agentic tasks (vendor numbers, third-party verification pending). Available on Hugging Face, NVIDIA NIM, build.nvidia.com, OpenRouter, and Perplexity Pro. Correction to earlier coalition note: Nemotron 3 Super (120B total / 12B active, 1M-token context) had already shipped 2026-03-11 -- the 'Super/Ultra expected H1 2026' framing is obsolete

Nemotron 3 now has dedicated sub-families for voice, retrieval, and safety beyond the original reasoning family. Published sub-lineup: (1) Nemotron Speech -- open-source ASR models, claimed 10x faster than class competitors at comparable WER; (2) Nemotron RAG -- multimodal embedding + reranker VLMs for enterprise retrieval; (3) Nemotron Safety -- Llama Nemotron Content Safety + Nemotron PII detector; (4) Nemotron 3 VoiceChat -- full-duplex voice agent in early access post-GTC 2026; (5) Nemotron 3 Content Safety guardrail. All released under the permissive Nvidia Open Model License

NEMOTRON COALITION: Announced at GTC March 2026, Nvidia leads an open-frontier coalition with Black Forest Labs, Cursor, LangChain, Mistral, Perplexity, Reflection AI, Sarvam, and Thinking Machines. Nemotron 4 (the first coalition model) has no public release date yet. Nemotron 3 rollout since completed: Nano first, Super 2026-03-11, Ultra 2026-06-04

Top AIToolTier-ranked alternatives in the same category, ordered by our overall score.

Qwen (Alibaba)

8.8

**Qwen-Image-2.1 went open-weight (weights 2026-09-14, blog 2026-09-20)** -- a unified text-to-image and editing model with a 7B visual-generation component, native transparent (RGBA) output, up to 10 reference images and mask-guided local edits -- but under a **research-only licence, not Apache**: commercial use needs a separate licence from Alibaba. Alibaba's open-weights + API family, and August 2026 was its biggest open-release month yet: **Qwen3.8-2.4T-A95B -- the Max-class flagship -- went open-weight on 2026-08-08** (custom Qwen3.8-Max licence), **Qwen3.8-27B** dense landed Apache 2.0 (8/05), and **Qwen3.8-Flash-Next** (8/24 weights, 8/26 blog) previews the Qwen4 architecture: 125B main + 51B n-gram embeddings with only 6B active, served as Qwen3.8-Flash at $0.15/$0.47 per 1M. Qwen 3.7 Max remains the GA API flagship ($2.50/$7.50)
