Neste guia, mostramos como migrar seu código Python usando a API PaLM para
a API Gemini. É possível gerar conversas de texto e de várias interações (chat) com o Gemini, mas verifique suas respostas, porque elas podem ser diferentes das saídas do PaLM.
Resumo das diferenças da API
Os nomes dos métodos foram alterados. Em vez de ter métodos separados para gerar
texto e chat, há um método generate_content que pode fazer ambos.
O Chat tem um método auxiliar start_chat que simplifica o chat.
Em vez de funções independentes, as novas APIs são métodos da
classe GenerativeModel.
A estrutura de resposta de saída foi alterada.
As categorias das configurações de segurança mudaram. Consulte o guia de configurações de segurança para mais detalhes.
