On July 24, Nvidia signed 'Open Weights and American AI Leadership' alongside Microsoft, Meta, IBM, Hugging Face and Mistral. The letter argues that U.S. AI leadership requires not just powerful frontier models but an open ecosystem that spreads AI capabilities across the economy, distinguishing open-weight models—whose parameters can be downloaded, run and modified under licences like Apache 2.0—from closed models accessed only via API.

Strands harness is a preassembled agent harness that developers can run locally or deploy to cloud providers with a single line of Python or TypeScript code, released under an Apache 2.0 license. It is designed as a general-purpose agent rather than a coding-specific one, and its makers report it costs 28% less than comparable harnesses across six benchmarks while maintaining similar or better accuracy, and 77% less than Claude Code on the Fable 5 benchmark while scoring higher on Terminal Bench 2.1.

A new ternary-quantized model, Ternary Bonsai 2 27B, has been released, built on Qwen3.8 27B and using {-1,0,+1} weights with FP16 group scaling to shrink the model to about 1.76 effective bits per weight and a 5.9GB footprint. Despite being over 9x smaller than its full-precision counterpart, it retains 98.2% of aggregate benchmark performance across reasoning, coding, vision and agentic tasks, and supports a 262K-token context window under an Apache 2.0 license.

IFM has launched K2 Horizon, a family of six models ranging from 0.9B to 375B-A23B parameters, released under Apache 2.0 with datasets under licenses like ODC-BY. Unlike typical open-weight releases, IFM is publishing the entire training lifecycle—intermediate checkpoints, data recipes, architecture details, training code, logs, and evaluations—alongside final weights. The smallest models (0.9B, 3.7B, 7B) reportedly set new state-of-the-art benchmarks for their size class.

Martin von Zweigbergk, who built the Jujutsu version control system while at Google, has been named chief technology officer of East River Source Control, a startup developing next-generation version control platforms. He will oversee engineering there while continuing as a core maintainer of Jujutsu, which remains open source under Apache 2.0. ERSC's storage product is set to enter private beta later this month.
