Microsoft announced at Build 2026 that Foundry Managed Compute now includes a curated catalog of open-weight models from Hugging Face's 3 million model repository, refreshed weekly with one-click deployment. The service pre-stages weights in Azure, provides Microsoft-scanned runtimes (vLLM, SGLang, TensorRT-LLM, NIM, TEI, llama.cpp), and offers pay-per-hour GPU pricing with automatic security patching.

Google DeepMind released Gemma 4, a family of four open models ranging from 2B to 31B parameters, all licensed under Apache 2.0. The 31B dense model ranks #3 on Arena AI's text leaderboard and the 26B mixture-of-experts variant ranks #6, outperforming closed models significantly larger in size.
