Five essential design patterns for building AI agents — from simple ReAct loops to multi-agent collaboration, graph-based workflows, and agent handoffs. With code examples and framework recommendations.
A practical comparison of the six major AI agent frameworks in 2026 — with code examples, feature matrices, and selection guidance for different use cases.
Understanding the protocol layer that connects agents to tools, other agents, and frontends — MCP, A2A, AG-UI, and native Function Calling compared.
Taking agents from prototype to production — covering observability with Langfuse, evaluation strategies, security guardrails, low-code platforms, and deployment architecture.
A silent bug in Hugging Face Transformers caused GPT-2 attention scaling configs to be ignored when using SDPA or FlashAttention backends. Here's how I traced, fixed, and tested it through three rounds of maintainer review.
