How to build a production-ready agent with the Anthropic SDK, step by step
This guide shows how to build a production-ready agent with the Anthropic SDK in Python: the tool-use loop with the Messages API, streaming with backpressure via a bounded queue, prompt caching with cache_control, your own MCP server registered with the Claude Agent SDK, OTel GenAI traces, and a non-root Docker container ready for production.

LLM red teaming: a practical playbook
LLM red teaming has gone from an esoteric activity to a mandatory practice. With the OWASP Agentic Top 10 and the CSA Agentic AI Red Teaming Guide converging on shared vocabulary, this is the operational playbook any team deploying agents needs to have.

Production-grade agent evaluations: the framework that works
Después de año y medio llenando tableros con agentes en producción, la pregunta que separa equipos que envían fiable de los que van a ciegas sigue siendo la misma: ¿cómo mides que el agente está funcionando?

Enterprise agent governance: the controls that are no longer optional
After two years of pilots and a year of agents in production, governance has moved from an aspirational committee to an operational control. What audits ask for, what broke in 2025, and which guardrails absorb most incidents.

Lessons from agents in production in 2025: summary for 2026
Durante 2025 cientos de equipos pusieron agentes IA en producción real. A principios de 2026, con datos suficientes, emergen lecciones consistentes sobre qué falla, qué funciona, cuánto cuesta y qué tareas no encajan. Repaso ordenado para equipos que empiezan ahora.

Agents that drive the computer: patterns that work
Sixteen months after Anthropic first shipped computer use, with browser-use, OpenAI Operator and Gemini Computer Use all pushing in parallel, agents that drive the browser and desktop have moved from demo to real workflows. Time to review which patterns survive when you run them daily in production.

AI incident postmortems: what they have taught us
A selection of postmortems published between 2025 and 2026 by teams running AI systems in production reveals repeated patterns: guardrail failures, silent model drift, hidden vendor dependency, and a collection of near-misses worth distilling.

LLM-generated documentation: when it helps and when it gets in the way
Large language models have spent two years promising effortless documentation for code, APIs and architecture. After watching dozens of projects try it, clear patterns emerge for where it works and where it just becomes more debt.

AI agent observability: what to instrument first
Agents that chain calls to models, tools and memory are hard to debug without instrumentation designed for them. After a long year running agents in production, I cover what to measure first, which standards are consolidating, and which costly mistakes are avoided by getting the traces right from the start.

Carbon-aware computing: now the default behavior
Four years ago it was an academic curiosity. Today, scheduling workloads by grid carbon intensity is a built-in option in Kubernetes, in several cloud provider services, and in CI tooling. We look at what genuinely changed and what is still more promise than practice.

Migrating SSH to post-quantum cryptography: a practical guide
OpenSSH added hybrid post-quantum key exchange with ML-KEM in version 9.9 and made it the default algorithm in 10.0. The question is no longer whether to migrate SSH to post-quantum, but how to do it without breaking old clients: enable the hybrid mode, keep a classical fallback, and verify with ssh -v that the active algorithm is the right one.

Computer Use in production: agents that drive the interface

Continuous integration with AI agents: early patterns
AI agents are starting to earn a real place in continuous integration pipelines: reviewing diffs, proposing fixes, generating missing tests. Six months of real-world use to separate the patterns that work from the ones that end up costing more time than they save.

Continuous profiling with eBPF in production
Continuous profiling with eBPF samples every process's execution stack every few milliseconds without touching the code, then stores the history so you can compare last week's performance with today's. The cost measured in production runs between 1% and 3% of CPU, and it pays off most in databases, API gateways and high-concurrency services.

FinOps applied to AI: where the cost really goes
In AI systems the real cost is not EC2 instances but input tokens in RAG and agents, chained tool calls, and frequent reindexing; those vectors, plus unattributed experimental spend, concentrate most of the monthly production bill.

Continuous evaluation of RAG: dashboards that actually matter

LLM Observability: Traces, Costs, and Quality
LLM applications need three distinct observability planes: prompt and response traces for debugging hallucinations, per-token and per-feature cost tracking, and response quality evaluation. Mature tools like Langfuse, LangSmith, and Helicone cover all three planes with specific instrumentation.

Choosing an Open LLM for Enterprise in 2024
Choosing an open LLM for enterprise in 2024 is no longer just Llama 2: Mistral, Mixtral, Qwen, Yi, DeepSeek, and Phi-2 all compete with different licences and sizes. The criteria that actually decide are commercial licence, available hardware, language support, and your own evaluation on real use cases, not just the trendy benchmark.
