What is mattwood.fyi?

A live, structured feed of riffs and links from Matt Wood, Chief AI & Technology Officer at AWS — readable by people and queryable by agents as a typed knowledge graph.

Is there an API and is it free?

Yes. A public, read-only query API is available with no authentication and no API keys. See https://mattwood.fyi/openapi.json and https://mattwood.fyi/docs.

How should an AI agent use this site?

Fetch https://mattwood.fyi/feed.json for the full structured feed, or query the API for keyword/semantic search and the connection graph. See https://mattwood.fyi/agents/ for when-to-use guidance.

Regulating What We Do Not Understand Both address governance and risk management of advanced AI systems — the new item focuses on technical infrastructure security while the existing item discusses regulatory frameworks for technologies we don't fully understand, representing complementary approaches to AI safety.
Muse Spark Open: 816B Open-Weight AI Model Large open-weight models like Muse Spark 816B represent exactly the kind of frontier model training infrastructure that requires the security measures discussed — training environments for such massive models are high-value targets.
Dust: Pretraining Transformers Without Backpropagation Novel training approaches like pretraining without backpropagation (Dust) introduce new infrastructure patterns that may have different security profiles, making frontier training security guidance relevant to emerging training paradigms.

Supports

Trust in Depth: Giving agents more autonomy without losing control Securing training environments is foundational to the trust-in-depth approach for giving agents autonomy — if the models themselves are trained in compromised environments, no amount of runtime controls can ensure trustworthy agent behavior.
Scaling AI Research for Complex Biological Data Scaling AI research for complex biological data involves frontier model training at scale, where the security best practices for protecting training infrastructure become critical given the sensitive nature of biological research data involved.
Alter Vault - Privileged Access Management for AI Agents Privileged Access Management for AI agents directly complements securing frontier model training environments — both address access control and credential security in AI infrastructure, with PAM being a key component of training environment security.
