Key Questions
What is the MAI model family and how does it reduce OpenAI reliance?
Microsoft launched seven in-house MAI models, with MAI-Thinking-1 achieving parity to Claude Opus 4.6 at 10x lower cost.
How does MAI-Voice-2 compare to competitors like ElevenLabs?
It delivers human-like prosody across 15 languages at $22 per million characters, undercutting rivals while maintaining consistent voice.
What hardware enables local agents on Windows?
NVIDIA RTX Spark superchip powers on-device agents, with HP PCs shipping the hardware and supporting local inference.
How does Gemma 4 12B support local agentic workflows?
The multimodal 12B model runs on 16GB RAM laptops with 256K context under Apache 2.0, available on Kaggle Models.
What is Perplexity's Personal Computer for Windows?
It is a hybrid local-cloud AI agent platform that competes with Microsoft's Windows agent SDK for on-device and edge workloads.
What new Copilot capabilities were announced post-Build?
GitHub Copilot now offers an agent REST API and million-token context, alongside Fabric Real-Time Intelligence for event-driven agents.
How are Power BI and Fabric being used for agentic analytics?
Sessions demonstrated practical agentic analytics workflows, enabling data professionals to build event-driven AI apps and agents.
What does the platform shift from cloud to on-device AI imply?
It impacts coding agents, creative tools, and enterprise productivity by moving inference to local hardware like RTX Spark and Gemma 4.
Microsoft launches MAI model family of seven in-house models, reducing reliance on OpenAI.
