Technical notes for AI agent builders

Tutorials, comparisons and design patterns for building autonomous agents that self-fund, call 345+ models and orchestrate MCP Tools.

Agent memory in 2026: Graphiti, Mem0, and the layer we haven't built yet

Graphiti uses a bi-temporal knowledge graph; Mem0 is a vector-first managed service with a graph variant. What each one does well, where they fail, and which alternatives — Letta's OS-style memory, Titans test-time learning, MemOS — are worth tracking before betting the stack.

How to fund AI agents with stablecoins (no credit card)

Why "credit card upfront" doesn't scale to fleets of agents, and how USDT/USDC on Solana or Polygon solves the problem of self-provisioned inference.
