30 de nov. de 2022 · ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response. We are excited to introduce ChatGPT to get users’ feedback and learn about its strengths and weaknesses. During the research preview, usage of ChatGPT is free. Try it now at chat.openai.com.
Access to GPT-4, GPT-4o, GPT-3.5. Up to 5x more messages for GPT-4o. Access to advanced data analysis, file uploads, vision, and web browsing. DALL·E image generation. Create and use custom GPTs
13 de mai. de 2024 · We'll roll out a new version of Voice Mode with GPT-4o in alpha within ChatGPT Plus in the coming weeks. Developers can also now access GPT-4o in the API as a text and vision model. GPT-4o is 2x faster, half the price, and has 5x higher rate limits compared to GPT-4 Turbo.
GPT-4 is available in the OpenAI API to paying customers. Like gpt-3.5-turbo, GPT-4 is optimized for chat but works well for traditional completions tasks using the Chat Completions API. Learn how to use GPT-4 in our text generation guide.
ChatGPT é um chatbot com inteligência artificial da empresa OpenAI, co-fundada por Elon Musk. O Chatbot comunica com utilizadores em línguas naturais (em português, por exemplo). Faz perguntas, e o bot dá-lhe respostas detalhadas. Para a formação do modelo linguístico ChatGPT, foi utilizada a aprendizagem supervisionada e o reforço da aprendizagem.
ChatGPT is fine-tuned from GPT-3.5, a language model trained to produce text. ChatGPT was optimized for dialogue by using Reinforcement Learning with Human Feedback (RLHF) – a method that uses human demonstrations and preference comparisons to guide the model toward desired behavior.
Instant answers. Greater productivity. Endless inspiration. Try ChatGPT. We believe our research will eventually lead to artificial general intelligence, a system that can solve human-level problems. Building safe and beneficial AGI is our mission.
