Modelos, agentes, aplicações: a inteligência artificial posta a trabalhar em problemas reais.
Aqui, a inteligência artificial é julgada pelas provas: o que faz, para quem, a que custo. A secção segue os modelos e os seus progressos mensuráveis, os agentes que executam tarefas reais e, sobretudo, as implantações — um hospital que rastreia mais doentes, uma rede elétrica mais bem gerida, uma administração que responde mais depressa. A IA-espetáculo, as rondas de financiamento sem produto e as profecias não têm aqui lugar.
Preferimos os casos de uso documentados, com os números à vista: quantos exames, que taxa de erro, que poupança. Os atores não ocidentais — laboratórios chineses, indianos, dos Emirados — são tratados como os americanos, porque boa parte da implantação real acontece aí. Cada artigo cita as suas fontes e distingue o protótipo do serviço em produção.
