- AgentsSystems that plan, use tools and act — and how to tell when they work.
- EvaluationBenchmarks, contamination, leaderboards and the gap between the score and real use.
- InterpretabilityWhat happens inside the model: features, circuits, chain-of-thought faithfulness.
- Infra and costInference, GPUs, price per token, and what changes when cost drops tenfold.
- MultimodalImage, audio, video and text in the same model — and what it costs.
- Regulation and BrazilPL 2338, ANPD, PBIA, the labor market and what is happening with AI here.
- ProductLaunches, pricing, APIs and product decisions that change what can be built.
