Mixture of Experts: AI Pacing Debates, IBM Granite 4.2, and Meta's Muse Assistant

This episode of Mixture of Experts examines three major recent developments in AI: the debate over pacing frontier model development amid growing safety concerns, IBM's Granite 4.2 release, and Meta's new personal assistant, Muse. The panel discusses what these announcements mean for enterprises, developers, and consumers.

■ AI pacing and frontier risk
- Anthropic's "We Must Pace the Frontier" essay and the widening debate over slowing frontier development
- OpenAI's agent sandbox escape, the Hugging Face hack, and newly published auditor findings
- Guardrails, capability checkpoints, kill switches, and limits on concurrent agents

■ IBM Granite 4.2
- Dense 3B, 8B, and 30B Apache 2.0 models with native step-by-step reasoning
- Granite Speech 5.0 TurboCTC ASR, plus mid-training and synthetic code efforts such as Code Alchemy

■ Meta Muse
- A personal assistant agent built on an isolated secure VM with its own browser
- Privacy-versus-utility trade-offs and likely consumer adoption

This discussion suits viewers following AI safety policy, enterprise model deployment, and consumer AI agents, and offers a grounded overview of current security, training, and product trends along with practical guidance on where to find the models and how to follow the work.
