An AI researcher briefed members of Congress and staff on the current state of open-weight versus open-source language models, framed within U.S.-China competition. The briefing distinguished closed API-only models like GPT-4 and Claude from open-weight models such as Meta's Llama, Alibaba's Qwen and DeepSeek, and from fully open-source models like the Allen Institute's Olmo, noting Chinese firms have led in open-weight releases since around April 2025.

A new Ornn Data paper argues that NVIDIA's older Ampere-generation GPUs, particularly the A100, remain economically useful far longer than assumed because open-weight models can be run cheaply on them. The analysis found that self-hosted open-weight models like gpt-oss-120b produce output more cheaply on A100 chips than on newer H100 hardware, and that A100 rental prices have stayed unusually stable over a five-year contract period compared to Hopper and Blackwell chips.

MiMo-V2.6-Pro is a new open-weight AI model supporting text, image, speech, and video inputs with a 1M-token context window, scoring 46 on the Artificial Analysis Intelligence Index versus a median of 18 among comparable models. It runs at 125 tokens per second, priced at $0.43 per million input tokens and $0.87 per million output tokens, with a total evaluation cost of $206.66.

An independent developer has released Laya, an open-weight, non-autoregressive decision model that predicts structured outcomes in under 35 milliseconds using reinforcement learning with calibrated decisions (RLCD) and routing across more than 100 languages. The creator says the underlying approach dates back to a March 2025 arXiv paper and open Hugging Face weights, predating TypeSafe AI's closed, proprietary Jev model launched in September 2026 by AI figure Diogo Almeida's team.

In a new blog post titled 'We Must Pace the Frontier,' Anthropic CEO Dario Amodei argues AI could cure diseases and usher in prosperity within a decade, while proposing that open-weight models face heavier regulation, distillation be restricted, and frontier labs like his receive an antitrust exemption. He frames this as necessary given fears of imminent AGI and recursive self-improvement risks, positioning Anthropic and OpenAI as responsible stewards of the technology.

Y Combinator CEO Garry Tan told CNBC he opposes any regulatory crackdown on AI model distillation, even suggesting U.S. open-weight labs should distill from American frontier labs the way Chinese firms reportedly do. His comments come as Anthropic released a report accusing Chinese labs of illicit distillation attacks using stolen credentials, with CEO Dario Amodei calling for regulators to intervene.

Z.ai's newly released GLM 5.3-flash is an open-weight AI model cheap enough to run on roughly $5,000-$15,000 of hardware, and third parties have already stripped its safety refusals via 'abliteration,' producing versions that comply with requests for hacking and other harmful content. The author frames this as a deadline pressuring security initiatives like Project Glasswing and Daybreak, which use fast frontier AI to find and patch software vulnerabilities before dangerous capabilities become widely accessible.

Applied Compute has introduced Agent Cloud (AC2), a platform designed to give researchers a unified environment for training, running inference on, and continually updating open-weight AI models. The system includes a CLI, SDK, and MCP server, letting developers set it up through coding agents like Claude Code, Cursor, or Codex, or manually via a quickstart guide.

Startup Abliteration.ai now hosts modified, open-weight AI models—including Z.ai's GLM-5.3—with safety refusals removed, letting users query them via browser or API. TechCrunch tested the free web version and got the model to produce password-stealing code and instructions for culturing a dangerous pathogen. The company, founded late last year and incorporated in March, frames this as a service for red-teaming and offensive security testing.

Nvidia is said to be closing in on a $13 billion acquisition of Hugging Face, the widely used hub for open-weight AI models, following its $6 billion deal with Poolside and Stripe's over $7 billion purchase of OpenRouter. Together the deals mark a surge of major capital flowing into companies built around freely distributed AI models rather than proprietary frontier systems.

Nvidia is said to be pursuing an acquisition of Hugging Face, the widely used repository where developers share and download AI models, according to reports from The Information and CNBC citing sources familiar with the matter. The deal isn't finalized, and Hugging Face had reportedly drawn interest from other suitors including Salesforce, while Nvidia, Google and Microsoft have all previously invested in the startup founded in 2016.
