Here is your AI Dev Brief from Marktechpost, covering core research, models, infrastructure tools, and applied updates for AI developers and researchers.
Microsoft AI Releases Fara-7B: An Efficient Agentic Model for Computer Use
Fara-7B is Microsoft’s 7B parameter, open weight Computer Use Agent that runs on screenshots and text to automate real web tasks directly on user devices. Built on Qwen2.5-VL-7B and trained on 145,603 verified trajectories from the FaraGen pipeline, it achieves 73.5 percent success on WebVoyager and 38.4 percent on WebTailBench while staying cost efficient and enforcing Critical Point and refusal safeguards for safer browser automation.

NVIDIA AI Releases Nemotron-Elastic-12B: A Single AI Model that Gives You 6B/9B/12B Variants without Extra Training Cost
Nemotron-Elastic-12B is a 12B parameter hybrid Mamba2 and Transformer reasoning model that embeds elastic 9B and 6B variants in a single checkpoint, so all three sizes are obtained by zero shot slicing with no extra distillation runs. It uses about 110B tokens to derive the 6B and 9B models from the 12B teacher, reaches average scores of 70.61, 75.95, and 77.41 on core reasoning benchmarks, and fits 6B, 9B, and 12B into 24GB BF16 for deployment.

Germany based open-source remote access company - NetBird just built an "AI Mega Mesh". A project that started out to prove that multi-cloud networking doesn’t have to be complicated, resulted in creating a secure AI inference infrastructure that connects GPU resources across multiple cloud providers using Microk8s, vLLM, and NetBird.
