+Este aplicativo apresenta o modelo **ÓUSI PREMIUM/florence**, um poderoso sistema de IA projetado para tarefas de **geração de texto e imagem**. O modelo é capaz de lidar com tarefas complexas como detecção de objetos, legendagem de imagens, OCR (Reconhecimento Óptico de Caracteres) e análise detalhada de imagens baseadas em regiões.
+
+### Uso e Flexibilidade do Modelo
+
+- **Sem Repetição de N-Gramas**: Para reduzir a repetição na geração de texto, o modelo é configurado com um **no_repeat_ngram_size** de **{no_repeat_ngram_size}**, garantindo saídas mais diversificadas e significativas.
+- **Estratégias de Amostragem**: ÓUSI PREMIUM/florence oferece estratégias de amostragem flexíveis, incluindo **top-k** e **top-p (nucleus) sampling**, permitindo tanto geração criativa quanto restrita, com base nas necessidades do usuário.
+
+📸📈✍🏻florence é um modelo robusto capaz de lidar com várias tarefas de **texto e imagem** com alta precisão e flexibilidade, tornando-se uma ferramenta valiosa para pesquisas acadêmicas e aplicações práticas.
+
+### **Como Usar**:
+1. **Faça o Upload de uma Imagem**: Selecione uma imagem para processamento.
+2. **Escolha uma Tarefa**: Escolha uma tarefa no menu suspenso, como "Legenda", "Detecção de Objetos", "OCR", etc.
+3. **Processar**: Clique no botão "Processar" para permitir que ÓUSI PREMIUM/florence analise a imagem e gere a saída.
+4. **Ver Resultados**: Dependendo da tarefa, você verá uma imagem processada (por exemplo, com caixas delimitadoras ou rótulos) ou um resultado baseado em texto (por exemplo, uma legenda gerada ou texto extraído).
+
+Você pode redefinir a interface a qualquer momento clicando no botão **Redefinir**.
+
+### **Tarefas Disponíveis**:
+- **✍🏻Legenda**: Gere uma descrição concisa da imagem.
+- **📸Detecção de Objetos**: Identifique e rotule objetos dentro da imagem.
+- **📸✍🏻OCR**: Extraia texto da imagem.
+- **📸Proposta de Região**: Detecte regiões-chave na imagem para legendagem detalhada.

+O modelo **ÓUSI PREMIUM/florence** é um modelo de ponta para tarefas de geração condicional, projetado para ser altamente eficaz em tarefas de **texto** e **visão**. É construído como uma arquitetura de **codificador-decodificador**, que permite maior flexibilidade e desempenho na geração de saídas com base em entradas diversificadas.
+
+### Principais Características
+
+- **Arquitetura do Modelo**: ÓUSI PREMIUM/florence usa uma estrutura de codificador-decodificador, o que o torna eficaz em tarefas como **geração de texto**, **resumo** e **tradução**. Ele possui **{num_layers} camadas** tanto para o codificador quanto para o decodificador, com uma dimensão do modelo (`d_model`) de **{d_model}**.
+- **Geração Condicional**: O modelo pode gerar texto condicionalmente, com um comprimento máximo de **{max_length} tokens** para cada sequência gerada, tornando-o ideal para tarefas que exigem saída concisa.
+- **Busca em Feixe**: ÓUSI PREMIUM/florence suporta **busca em feixe** com até **{beam_size} feixes**, permitindo geração de texto mais diversa e precisa explorando múltiplas potenciais saídas antes de selecionar a melhor.
+- **Tokenização**: Inclui um tokenizador com um vocabulário de **{vocab_size} tokens**. Tokens especiais como **bos_token_id (0)** e **eos_token_id (2)** ajudam a controlar o processo de geração, marcando o início e o fim de uma sequência.
+- **Mecanismo de Atenção**: Tanto o codificador quanto o decodificador utilizam **{attention_heads} cabeças de atenção** por camada, garantindo que o modelo possa focar em partes relevantes da entrada ao gerar texto.
+- **Dropout e Ativação**: ÓUSI PREMIUM/florence emprega uma **função de ativação {activation_function}** e uma **taxa de dropout de {dropout}**, o que melhora o desempenho do modelo prevenindo overfitting e melhorando a generalização.
+- **Configuração de Treinamento**: O modelo usa precisão **float32** para treinamento e suporta fine-tuning para tarefas específicas ao configurar `finetuning_task` apropriadamente.
+
+### Integração de Visão
+
+Além das tarefas de texto, ÓUSI PREMIUM/florence também incorpora **capacidades de visão**:
+- **Processamento de Imagem Baseado em Patches**: O componente de visão opera em patches de imagem com um tamanho de patch de **{patch_size}x{patch_size}**.
+- **Embedding Temporal**: Tarefas visuais se beneficiam de embeddings temporais com até **{temporal_embeddings} passos**, tornando o florence bem adequado para análise de vídeo.

+"""
+how_to_use = """As configurações avançadas permitem que você ajuste o processo de geração de texto. Aqui está o que cada configuração faz e como usá-la:
+
+### Top-k (Padrão: 50)
+A amostragem top-k limita a seleção do próximo token aos k tokens mais prováveis.
+
+- **Valores mais baixos** (por exemplo, 10) tornam a saída mais focada e determinística.
+- **Valores mais altos** (por exemplo, 100) permitem saídas mais diversificadas.
+
+**Exemplo:** Para uma tarefa de escrita criativa, tente definir top-k para 80 para uma linguagem mais variada.
+
+### Top-p (Padrão: 1.0)
+A amostragem top-p (ou nucleus) seleciona do menor conjunto de tokens cuja probabilidade cumulativa excede p.
+
+- **Valores mais baixos** (por exemplo, 0.5) tornam a saída mais focada e coerente.
+- **Valores mais altos** (por exemplo, 0.9) permitem saídas mais diversificadas e potencialmente criativas.
+
+**Exemplo:** Para uma legenda factual, defina top-p para 0.7 para equilibrar precisão e criatividade.
+
+### Penalidade de Repetição (Padrão: 1.0)
+Esta penaliza a repetição no texto gerado.
+
+- **Valores próximos a 1.0** têm efeito mínimo na repetição.
+- **Valores mais altos** (por exemplo, 1.5) desencorajam mais fortemente a repetição.
+
+**Exemplo:** Se você notar frases repetidas, tente aumentar para 1.2 para um texto mais variado.
+
+### Número de Feixes (Padrão: 3)
+A busca em feixe explora múltiplas sequências possíveis em paralelo.
+
+- **Valores mais altos** (por exemplo, 5) podem levar a melhor qualidade, mas geração mais lenta.
+- **Valores mais baixos** (por exemplo, 1) são mais rápidos, mas podem produzir resultados de menor qualidade.
+
+**Exemplo:** Para tarefas complexas como legendagem densa, tente aumentar para 5 feixes.
+
+### Máximo de Tokens (Padrão: 512)
+Define o comprimento máximo do texto gerado.
+
+- **Valores mais baixos** (por exemplo, 100) para saídas concisas.
+- **Valores mais altos** (por exemplo, 1000) para descrições mais detalhadas.
+
+**Exemplo:** Para uma descrição detalhada da imagem, defina o máximo de tokens para 800 para uma saída abrangente.
+
+Lembre-se, essas configurações interagem entre si, então experimentar diferentes combinações pode levar a resultados interessantes!
