O que é “vibe coding”?

Um vídeo publicado no X mostrou Steve, o boneco do Minecraft, lutando dentro de Elden Ring, com a interface e a jogabilidade dos dois games perfeitamente integradas.

Juntar dois jogos tão diferentes exigiria, no passado, um trabalho enorme mesmo de programadores experientes. Hoje, está ao alcance de muitos amadores: basta pedir para uma IA.

[{"selector":"#anim-e9980728-50ab-4768-bbbe-807fd40e971d","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-9ee029bd-14ac-4cee-8bfe-6dbff2f74784","keyframes":{"transform":["rotate(-271deg) translate3d(474.99985%, 0px, 0) rotate(271deg)","rotate(-271deg) translate3d(0px, 0px, 0) rotate(271deg)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-2f0982aa-450d-47e2-a418-dd722a323ad7","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-6425c463-d32b-4bd6-a74d-2aa37da8a031","keyframes":{"transform":["translate3d(-117.41936%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Essa prática tem nome: vibe coding. O termo foi cunhado pelo pesquisador Andrej Karpathy em 2025 e descreve a programação feita por amadores com ajuda de IA, levados pela “vibe”.

[{"selector":"#anim-a4f520c3-2056-4a19-8b75-bf11a3b1edc5","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-0fb38ac8-0415-4139-8bf6-7e173912d7a7","keyframes":{"transform":["rotate(-271deg) translate3d(474.99985%, 0px, 0) rotate(271deg)","rotate(-271deg) translate3d(0px, 0px, 0) rotate(271deg)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-fa13b5be-63fe-437c-b120-91f5e6431385","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-bcaf4a2d-4222-487d-9e64-ce830f424f03","keyframes":{"transform":["translate3d(-117.41936%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

O vibe coding entrou na versão online do Merriam-Webster, o dicionário de inglês mais tradicional dos EUA, ao lado de termos de IA como “agentic” e “prompt engineering”.

[{"selector":"#anim-6b9cfb65-f679-4220-ad2d-e4a6e519c454","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5fe80689-7287-461a-b70d-efc75430e5d1","keyframes":{"transform":["rotate(-271deg) translate3d(474.99985%, 0px, 0) rotate(271deg)","rotate(-271deg) translate3d(0px, 0px, 0) rotate(271deg)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-f6c9d68c-cfb9-4127-856d-3661115e0788","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-44a219fb-0b60-4070-90c8-7aefffa4e68a","keyframes":{"transform":["translate3d(-117.41936%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Segundo o dicionário, quem faz vibe coding diz à IA o que quer e deixa que ela crie o produto. Não precisa entender como o código funciona e, muitas vezes, aceita certa quantidade de bugs.

[{"selector":"#anim-00c9b97b-e53f-4882-b46b-0b82bab1dac6","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-99ca28b2-c07a-4649-9886-f2d93d1bc369","keyframes":{"transform":["rotate(-271deg) translate3d(474.99985%, 0px, 0) rotate(271deg)","rotate(-271deg) translate3d(0px, 0px, 0) rotate(271deg)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-4829486f-d01a-4463-88e5-03e98feda62c","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d96e3860-5542-41c2-be44-d79eb064ae6e","keyframes":{"transform":["translate3d(-117.41936%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Esse é o ponto polêmico. Treinadas com trilhões de linhas de código, as IAs escrevem programas completos a partir de um único prompt, mas ainda cometem muitos erros.

[{"selector":"#anim-194c5529-a232-4d23-9b8e-cced4878113b","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e767ead0-076b-468f-a179-e27a093df6da","keyframes":{"transform":["rotate(-271deg) translate3d(474.99985%, 0px, 0) rotate(271deg)","rotate(-271deg) translate3d(0px, 0px, 0) rotate(271deg)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-39c0b280-be2a-4580-9f35-ddba548c9590","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d0d7c8b7-a879-4084-b1f8-678aaa396143","keyframes":{"transform":["translate3d(-117.41936%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Em sistemas com dados sensíveis, código desleixado vira vulnerabilidade. Um estudo do ano passado mostrou que 45% dos códigos gerados por IA falham em testes de segurança. Em Java, 72%.
