在OpenAI官網中可以免費使用GPT3.5了，大家可以體驗試試，我試了下可以正常使用。

It's core to our mission to make tools like ChatGPT broadly available so that people can experience the benefits of AI. More than 100 million people across 185 countries use ChatGPT weekly to learn something new, find creative inspiration, and get answers to their questions. Starting today, you can use ChatGPT instantly, without needing to sign-up. We're rolling this out gradually, with the aim to make AI accessible to anyone curious about its capabilities.

為了實現讓更多人體驗到人工智能的好處的使命，我們致力于讓像ChatGPT這樣的工具廣泛普及。每周有來自185個國家的1億多人使用ChatGPT，通過它學習新知識、尋找創作靈感和獲取問題的答案。從今天開始，您可以立即使用ChatGPT，無需注冊。我們正在逐步推出此服務，希望讓任何對人工智能能力抱有好奇心的人都可以輕松使用。

We may use what you provide to ChatGPT to improve our models for everyone. If you’d like, you can turn this off through your Settings - whether you create an account or not. Learn more about how we use content to train our models and your choices in our Help Center.

我們可能會使用您提供給ChatGPT的內容來改進我們的模型，使其對所有人都更加有效。如果您愿意，無論您是否創建帳戶，都可以通過設置關閉此功能。您可以在我們的幫助中心了解有關我們如何使用內容來訓練我們的模型以及您的選擇。

We’ve also introduced additional content safeguards for this experience, such as blocking prompts and generations in a wider range of categories.

There are many benefits to creating an account including the ability to save and review your chat history, share chats, and unlock additional features like voice conversations and custom instructions.

For anyone that has been curious about AI’s potential but didn’t want to go through the steps to set-up an account, start using ChatGPT today.

我們還為這一體驗引入了額外的內容保障措施，例如在更廣泛的類別中屏蔽提示和生成。

創建賬戶有許多好處，包括能夠保存和查看您的聊天記錄、分享聊天內容，并解鎖額外功能，如語音對話和自定義指導。

對于那些對人工智能的潛力充滿好奇，但又不想經歷設置賬戶的步驟的人，今天開始使用ChatGPT吧。
