Top 15 AI reads from the last 24 hours, curated from indie blogs, Substacks, and research.
The 15 most important things happening in AI today, sourced from blogs, Substacks, and researchers who matter.
1. Why Agents Love Supabase
Supabase founders break down why their Postgres-based backend has become the infrastructure of choice for AI agent systems. Understanding the database layer is critical as agents move from prototypes to production, especially for Bay Area teams building stateful, multi-step workflows.

3. Embeddings for AI Agent Memory: What Similarity Search Gets Wrong
Vector search is industry dogma for agent memory, but this piece challenges the assumption that cosine similarity actually solves the retrieval problem. Critical reading for anyone building memory systems that need to distinguish facts from contradictions.

4. Episodic, Semantic, and Procedural Memory in AI Agents
A framework for thinking about agent memory as fundamentally heterogeneous: past experiences, facts, and learned procedures each demand different storage and retrieval mechanics. Essential mental model for designing cognition in agentic systems.
