#Arquitetura De Software

Half the prompt techniques disappeared because the model learned them on its own. The other half became API parameters. What survived, what turned into folklore, and why in a real system the problem stopped being the sentence and became what goes into the context window.

A twelve-word post on X became a paradigm with its own paper in five weeks. I went and read the survey looking for the benchmark that justifies the new rung: there isn't one. What separates hype from engineering in graph engineering, with the numbers traced back to the source, which ones come from vendors and which are independent, and the five-question yardstick for deciding whether your case calls for a graph or you just want the new badge.

One OpenAI-compatible endpoint for hundreds of models, with automatic fallback between providers. What OpenRouter is, how to call it from curl, Python, and PHP, how to control routing, provider, and cost caps, and the scenarios where this extra layer hurts more than it helps.

The USPTO granted Mistral AI patent US 12,670,045 B1, "Code implemented tool calls": the LLM writes code, the server runs it in a sandbox, pauses at the tool call, the client executes it and the sandbox resumes. It's the programmatic tool calling the industry had already published. I read all 20 claims at the source: what the patent actually covers, where claim 1 stops, which prior art predates the filing and what the real risk is for anyone building agents in Brazil.
