#Produto IA

Brazilians live on WhatsApp, adopted Pix in five years and already buy through chat. Companies are still shipping forms: only 17% used AI in 2025. With data from Gartner, Cetic.br, the Central Bank and Opinion Box, why the shift from screens to natural language interfaces is the biggest open opportunity for Brazilian devs, what building an agent means in practice and the caveats the thesis has to face.

Tool lists rot in twelve months, yours included. That's why each of the ten comes with a swap criterion: the ten slots in the AI engineer's stack in 2026, the default for each one, and the objective signal that tells you when to rip it out. With data from the 2026 OWASP Top 10 and the Pragmatic Engineer survey.

Half of the "AI projects" I reviewed in 2026 could have been solved with an if and a SELECT. The other half became agents because the team wanted to say they had AI. Here's the 3-minute test: 4 questions that decide whether your problem calls for an if, a query, a prompt, a deterministic flow or an actual agent. With 5 real cases, the verdict on each one (spoiler: 1 in 5 was an agent) and the invisible cost of overshooting.

The third LLM infrastructure provider already has a São Paulo region, a catalog with Grok 4.3, Gemini 2.5, Llama 4, and Cohere Command A, and bills per character instead of per token. The real Oracle Generative AI catalog, how to call the service with the OpenAI SDK, the dedicated cluster math, and the objective criteria for deciding between OCI and Bedrock.

AWS documents how to turn on Bedrock really well. Nobody documents the rest: the difference between CloudTrail and model invocation logging, the fact that São Paulo doesn't give you data residency, and what shows up on the bill in reais at the end of the month. A practical guide to Claude in production on AWS Bedrock: model IDs, inference profiles, the four governance layers and the full cost breakdown for an internal agent.

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 Laravel AI SDK is Laravel's first-party AI package: agents as PHP classes, tool calling, structured output, streaming, embeddings with pgvector and fakes for testing without burning tokens. A practical guide from composer require to your first running agent, covering what the SDK solves, what it doesn't, and the limitations nobody tells you about.
