When i make the streaming request all the tokens come out just fine, and when the stream ends the last chunk in the stream is the whole stream with each token doubled and in prompt layer what is saved is this doubling.
below is the result of a single request, notice that everything looks good and then the content is doubled at the bottom

Overview: This video tutorial covers how to build fast, OpenAI applications with Next.js and Vercel Edge Functions. It explains the components of the application, such as the UI components, loading logic, and generate bio function. It also discusses the advantages of using Edge Functions with streaming, such as speed and user experience. 

**Components of the Application**

* UI components: images, text area to collect user's bio, drop-down to collect user's vibe, and generate your bio button.
* Loading logic: displaying generated bios.
* Generate bio function: calling OpenAI, setting prompt, and displaying it to the user.

**Advantages of Edge Functions with Streaming**

* No cold starts and significantly faster.
* Allows for a better user experience without needing to wait several seconds and showing the user a loading spinner before they finally see their data.

Overview: This section covers how to use the OpenAIStream helper function to enable OpenAI to send chunks of text as they come in.

**Using the OpenAIStream Helper Function**

* The OpenAIStream helper function opens up a stream with OpenAI, allowing for chunks of text to be sent back as they come in.
* Instead of waiting for every word to come in, this function enables faster applications with a great UI.

# [0:05:34](https://youtu.be/9Q9_CQxFUKY?t=334s) Examining the Code

Overview: This section covers how to examine the code and loop through values coming from the stream.

**Examining the Code**

* The code can be examined to understand how the OpenAIStream helper function works.
* By looping through values coming from the stream, the GeneratedBio state can be seen and results can be obtained.
