PRODUCTION

Self-host LiteLLM or Kong, or use a managed gateway like Portkey, OpenRouter, or Cloudflare AI Gateway? A factual breakdown of cost, control, and ops tradeoffs.

A practical comparison of LLM routing tools - LiteLLM, Portkey, and OpenRouter - covering cost management, fallbacks, caching, and when to use each for production AI applications.

A practical architecture for multi-step Claude agents. Loop patterns, state management, error recovery, and the production gotchas that turn a five-step demo into a 20 percent success rate at scale.

Configurable memory, sandbox-aware orchestration, Codex-like filesystem tools. Here is how the new Agents SDK actually behaves in prod.

The defensive patterns that keep Claude integrations alive in production. Retry shapes, backoff with jitter, circuit breakers, fallback chains, and the observability you need to debug at 3am.

GPT-5.4 ships state-of-the-art computer use, steerable thinking, and a million-token window. Here is the implementation guide for builders, with real OpenAI SDK code, the 272K pricing cliff, and where it actually beats 5.3 and 5.5 in production.

GPT-5.5-Codex merges Codex and GPT-5 stacks. Here is what the unified model means for real coding agents - latency, costs, prompt rewrites.

GPT-5.5 and 5.5 Pro hit the API on April 24. Here is what changes for builders: pricing, agentic tasks, tool-use, and the real benchmarks I ran the day it dropped.

OpenAI shipped an open-weight PII redactor. Here is how to wire it into a real ingestion pipeline locally, fast, with zero leaks, and how it benchmarks against Presidio and a regex baseline.

A production-grade RAG pipeline with Claude. Chunking that survives real documents, retrieval tuning that actually moves the needle, citation tracking, and the prompt caching trick that makes RAG cheap enough to ship.

The math of agent pipelines is brutal. 85% reliability per step compounds to about 20% at 10 steps. Here is why long chains collapse in production, and the six patterns the field has converged on to fight the decay.
