做网站和百度推广有什么不一样/今日军事新闻头条最新

今天在新闻上看到一条消息，OpenAI已经开放了ChatGPT的接口，也就是GPT-3.5，对比原来的GPT-3，增加了gpt-3.5-turbo、gpt-3.5-turbo-0301两个模型。

• gpt-3.5-turbo：使用最新的GPT-3.5模型，并针对聊天进行了优化，使用最新的模型进行迭代
• gpt-3.5-turbo-0301：属于 gpt-3.5-turbo的快照，此模型不会进行更新，并且在2023年6月1日停止支持
  因此，我们使用gpt-3.5-turbo就可以了。

对于GPT-3，GPT-3.5是支持上下文的。通过API，我们可以完成完整的聊天了。gpt-3.5-turbo的API如下：

• model：我们使用gpt-3.5-turbo
• messages：数组形式，例如：[{"role": "user", "content": "Hello!"}]，role分为三种角色，分别是system、assistant和user。
• temperature：取值是0-2，
• top_p：默认值是1，
• n：默认值是1
• stream：默认值是false
• stop：默认值是null
• max_tokens：最大值是4096
• presence_penalty：默认值是0
• frequency_penalty：默认值是0
• logit_bias：默认值是null
  其中，model和messages是必填的，其他，我们采用默认值就可以了
  根据上一篇文章，学习.NET MAUI Blazor（六）、基于OpenAI接口的伪ChatGPT，我们还是使用开源的SDK类库OpenAI-DotNet，该类库于3月2日升级到了5.0版本，新增了Chat接口，这样就可以实现聊天应用了。接着上一篇文章，我们来做一个真正的ChatGPT对话功能。

打开Shared/NavMenu.razor，修改内容如下：

<div class="top-row ps-3 navbar navbar-dark"><div class="container-fluid"><a class="navbar-brand" href="">OpenAI</a><button title="Navigation menu" class="navbar-toggler" @onclick="ToggleNavMenu"><span class="navbar-toggler-icon"></span></button></div>
</div><div class="@NavMenuCssClass" @onclick="ToggleNavMenu"><nav class="flex-column"><div class="nav-item px-3"><NavLink class="nav-link" href="" Match="NavLinkMatch.All"><span class="oi oi-home" aria-hidden="true"></span> 文本</NavLink></div><div class="nav-item px-3"><NavLink class="nav-link" href="chat" Match="NavLinkMatch.All"><span class="oi oi-chat" aria-hidden="true"></span> 对话</NavLink></div><div class="nav-item px-3"><NavLink class="nav-link" href="code"><span class="oi oi-plus" aria-hidden="true"></span> 代码</NavLink></div><div class="nav-item px-3"><NavLink class="nav-link" href="image"><span class="oi oi-list-rich" aria-hidden="true"></span> 图像</NavLink></div></nav>
</div>@code {private bool collapseNavMenu = true;private string NavMenuCssClass => collapseNavMenu ? "collapse" : null;private void ToggleNavMenu(){collapseNavMenu = !collapseNavMenu;}
}

接着在Pages目录下，新建一个Chat.razor。页面内容如下：

@using System.Text;
@using Mode;
@page "/chat"

编写Code代码

@code {public string question = "";private bool Boilerplate = false;private MVirtualScroll<QA> _vs;private List<OpenAI.Chat.ChatPrompt> chatPromptsList = new List<OpenAI.Chat.ChatPrompt>();private List<QA> _items = new();private async Task RequestAnswers(){Boilerplate = true;var api = new OpenAI.OpenAIClient(new OpenAI.OpenAIAuthentication(OpenAIConfig.api_key));OpenAI.Chat.ChatPrompt chatPrompt = new OpenAI.Chat.ChatPrompt("user", question);chatPromptsList.Add(chatPrompt);var chatRequest = new OpenAI.Chat.ChatRequest(chatPromptsList);QA qa = new();qa.question = question;var result = await api.ChatEndpoint.GetCompletionAsync(chatRequest);string answer = result.FirstChoice.Message.Content;answer = answer.ReplaceFirst("\r", "").ReplaceFirst("\n", "");qa.answer = answer;_items.Add(qa);Boilerplate = false;}}

至此，一个简单的聊天应用就完成了。运行效果如下：

从运行效果来看，使用GPT-3.5的接口，确实支持上下文了。

总结
注册了openai的账号，送的18刀比较耐用，自己玩了很久，才用了不到1刀。所以，下载下来，尽情玩耍吧。
