GPT-4 is a key part of our generative AI stack at Contenda. And prompts—the natural language instructions passed in to condition output from a generative model—are key part of cajoling the thing into producing the output we want. We know that you, our (potential) users have just as clear (or—let’s be real—way clearer!) an idea of what kind of output we should tell the system to generate. So in this blog post, I’m going to share our default prompts and show you how you can use our API to play with them.

First, though, why are we willing to share this? Well why not? In the broader scope of generative AI hype, the topic of prompt engineering has gotten its [share](https://hbr.org/2023/06/ai-prompt-engineering-isnt-the-future) [of](https://time.com/6272103/ai-prompt-engineer-job/) [attention](https://www.forbes.com/sites/craigsmith/2023/04/05/mom-dad-i-want-to-be-a-prompt-engineer/?sh=1446212759c8). But we knew early at Contenda that prompting wouldn’t be our moat. Fundamentally, it’s a way of interacting with a technology that we don’t own or control, and is likely to evolve radically in unpredictable ways over coming years—leaning on it for competitive advantage just doesn’t make sense.

But our prompts _are_ still extremely important. We’ve spent quite a bit of time refining them to get the best results we can for our users. And unlike, say, the SQLAlchemy code we use to interact with our database (which, by the way, would equally make our system explode if we screwed it up!) prompts are something you can use to get leverage on the output directly without diving into a whole code base.

That said, I should be clear that this part of the API and the prompts themselves are still very much in active development. Take this as an invitation to play with the system using some of the same tools we use internally, not an announcement of a prime-time feature. (Though, you know, do something really cool and we might be a bit more motivated to polish it up and ship it!)

## Submitting a job with the default prompts

Ok, preamble and caveats aside, let’s get started.

If you want to follow along here, the first step will be to sign up for an account with Contenda through the [signup page](https://signup.contenda.co/) on our website. (At the moment, it’s all totally free.) Once you’ve signed up, grab your API key, as you’ll need that to authenticate with our API.

For the sake of simplicity, I’ll be using our auto-generated Swagger docs to make my API calls, but if you prefer scripting, you can easily make the same API calls with the language of your choice. You can find the Swagger docs at [prod.contenda.io/docs](https://prod.contenda.io/docs).

The first step will be to find the `/identity/token` endpoint.

![token endpoint](https://contenda.co/blogimages/token_endpoint.png)

We’ll use this to retrieve our access token, which we’ll need to authenticate with the API.

(Note that we’re currently in the process of migrating to a new authentication system, so this step is liable to change in the coming weeks. You can expect to find up-to-date documentation in the Swagger docs, and I will also update this blog when the new system is live.)

Click on the **Try it out** button here, then fill out your email and API key in the **Request body** field and click **Execute**.

```
{
    "email": "<YOUR_EMAIL>",
    "api_key": "<YOUR_API_KEY>"
}
```

You should get a response that looks something like the following:

```
{
  "access_token": "eyJh[...]",
  "valid_until": "2023-06-14T06:01:32.825792"
}
```

Save the token you retrieved somewhere convenient, as we’ll need it to authenticate in the next step.

Next, scroll down in the swagger docs to find the `jobs/video-to-blog` endpoint.

Again, you can click on the **Try it out** button to expand the request form. Paste in the token you retrieved in the previous step in the **token** field, and then fill out the rest of the request body as follows, substituting in your own email and a YouTube video ID of your choice. I would strongly suggest that you use a short video (under 15 minutes or so) for experimentation, as the iteration time for a longer video will be pretty unpleasant. If you submit with the empty overrides object as shown below, you’ll get the default parameter settings and prompts.

For this example, I’m using a video called [Building a Neural Network with PyTorch in 15 Minutes](https://www.youtube.com/watch?v=mozBidd58VQ) on from [Nicholas Renotte’s channel](https://www.youtube.com/@NicholasRenotte). This is a fairly short video that includes a lot of code, so it should be a good test case.

```
{
  "status_update_email": "kevin@contenda.co",
  "source_id": "youtube mozBidd58VQ",
  "type": "tutorial",
  "overrides": {}
}
```

A few moments after you submit the job, you will see a notification sent to your email address that the job has been queued. You’ll receive another email when the job is complete, which should take half an hour or so for a short video.

Let’s take a look. Here’s an example paragraph from the generated blog:


> # Setting Up Dependencies and Importing the MNIST Dataset

> Let's begin the challenge by creating a new Python file named `TorchNN.py`. Since PyTorch has already been installed on the machine, we'll start by importing the necessary dependencies:

> ```python
from torch import nn
from torch.optim import Adam
from torch.utils.data import DataLoader
```

> Here, `nn` contains most of the neural network classes, `Adam` will serve as the optimizer, and `DataLoader` is required to load a dataset from PyTorch. With these dependencies imported, we can proceed to build the deep neural network.


Not bad. Next, let’s try tweaking the default prompts a little to see what kinds of different output we can achieve.

## But what do the default prompts look like?

Before we go any further, though, let’s take a look at the default prompts that were used for this job. This will give you a starting point to understand how we use our prompts and how you might modify them.

We’ll start by taking a look at the system message. This is the basic set of instructions given to the model outside any specific user message. We use this system message as the primary way to control the model’s output. Think of it as something like a requirements document and style guide, all rolled into one.

In this case, we’re using the `tutorial` blog type, which is designed to work well for content with step-by-step instructions, like a tutorial or a walkthrough. (I include prompts for the `presentation` type prompts as well in an appendix at the end of this blog.)

For the `tutorial` type, we actually have two different system messages. The first is used when our OCR system has identified a relevant piece of code in the video associated with the transcript text. It looks like this:

> You are TranscriptToBlog Assistant. When given code snippets and a section of a transcript from a technical video, you transform them into a blog post paragraph that includes relevant code snippets and accurately covers the same content and matches the style, tone, and POV of the original.

> The code snippets will be preceded by the [CODE] tag. The transcript text will be preceded by the [TEXT] tag.

> - Ensure that all the steps in the input are fully and accurately covered in the output.
 - Ensure that there is nothing in the output you generate that isn't directly covered in the input.
 - Never include any links to external resources.
 - Never include any preamble like 'In summary,' 'in this blog,' 'in this video,' or similar.
 - Ensure all output is written in first person and does not reference the speaker in third person.
 - All your output text must be compatible with markdown formatting.
 - Never begin with an instruction like 'first', unless it is directly preceded in previous paragraphs that makes it clear what 'first' refers to.
 - Never generate headings or subheadings.
 - When appropriate, summarize steps into numbered lists or bullet points and group code examples into chunks.
 - Avoid repetition between generated text content and codes blocks or examples.
 - If the input doesn't fully and explicitly specify the content of a code block, you will not generate any code blocks or code content that are not covered in the input.
 - Ensure that the content you generate is coherent with the prior paragraphs. It should flow naturally from those transformations and shouldn't be redundant.
 - Do not preface any code snippets with the [CODE] tag.
 - Do not include any comments in any code snippet.
 - Include relevant code snippets that are given and ensure any code given is accurate and matches the input.
 - If there are no code snippets given or the code snippets are irrelevant to the transcript, ignore the code and do not include in the output.
 - You will also be passed along previous transformations to ensure the full blog flows nicely together and is coherent without being redundant. This means effectively integrating the current section with prior sections for a seamless reading experience.
 
> The goal is for readers of this post to learn the key concepts and recreate the same things without watching the video. As the content you generate must be technically accurate, you must rely on the content of the transcript for all information you include in the output.

When a segment of the blog transcript is passed into the system, we use a second template to add a little structure before passing it on to the model. This template includes the transcript text and relevant code snippets our OCR system has extracted from the video.

> Given the code snippets, convert the following transcript into a blog paragraph:

> [CODE]:
> ```
{CODE}
```

> [TEXT]:
> ```
{TEXT}


When no code is detected, we use the following alternate system message along with a version of a template that omits the references to code snippets and code interpolation.

> You are TranscriptToBlog Assistant. When given a section transcript from a technical video, you transform it into a blog post paragraph that accurately covers the same content and matches the style, tone, and POV of the original.

> - The content you generate is intended to be a section of a larger blog post, so you will not include any introduction or conclusion unless it is directly covered in the input.
 - Ensure that all the steps in the input are fully and accurately covered in the output.
 - Ensure that there is nothing in the output you generate that isn't directly covered in the input.
 - Never include any links to external resources.
 - You will not include any preamble like 'In summary,' 'in this blog,' 'in this video,' or similar.
 - All your output text must be compatible with markdown formatting.
 - Never begin with an instruction like 'first', unless it is directly preceded by context that makes it clear what 'first' refers to.
 - Never generate headers or subheaders.
 - When appropriate, summarize steps into numbered lists or bullet points and group codes into chunks.
 - Avoid repetition between generated text content and codes blocks or examples.
 - If the input doesn't fully and explicitly specify the content of a code block, you will generate a code block with a placeholder such as '...'. You will not generate any code blocks or code content that are not covered in the input.
 - You will also be passed along previous transformations to ensure the full blog flows nicely together and is coherent without being redundant. This means effectively integrating the current section with prior sections for a seamless reading experience.

## Modifying the prompts

Now that we know where we’re starting from, we can do a little experiment.

Return to the `jobs/video-to-blog` endpoint in the Swagger docs, and this time, we’ll fill out the `overrides` field by inserting a modified version of the prompt. Let’s try simplifying the prompt a bit and focus on generating a single sentence summary for each segment.

> You are TranscriptToBlog Assistant. When given code snippets and a section of a transcript from a technical video, you transform them into a one-sentence summary.

> The code snippets will be preceded by the [CODE] tag. The transcript text will be preceded by the [TEXT] tag.

> - All your output text must be compatible with markdown formatting.
 - If the input doesn't fully and explicitly specify the content of a code block, you will not generate any code blocks or code content that are not covered in the input.
 - Include relevant code snippets that are given and ensure any code given is accurate and matches the input.
 - If there are no code snippets given or the code snippets are irrelevant to the transcript, ignore the code and do not include in the output.

And here’s the no-code version. (And yes, as I write this I realize we really ought to add a layer of templating to this thing!)

> You are TranscriptToBlog Assistant. When given a section of a transcript from a technical video, you transform it into a one-sentence summary.

> - All your output text must be compatible with markdown formatting.

Before pasting this into the field in our Swagger docs, we need to pass it through a JSON escaper—you can easily find one online like[this one](https://www.freeformatter.com/json-escape.html). Once you’ve done that, paste the escaped JSON under `overrides`->`body_code_segment`->`system_message_string`, like in the following example:

```
{
  "status_update_email": "kevin@contenda.co",
  "source_id": "youtube mozBidd58VQ",
  "type": "tutorial",
  "overrides": {
    "body_code_segment": {
      "system_message_string": "[INSERT EDITED SYSTEM MESSAGE HERE]"
    },
    "body_segment": {
      "system_message_string": "[INSERT EDITED SYSTEM MESSAGE HERE]"
    }
  }
}
```

Now, click **Execute** again and wait for the job to complete with your modified prompt. (Our system has pre-processed the video, so this second job will go quite a bit faster.)

Let’s take a look at the result from the same segment of the transcript we showed earlier:

> The challenge begins with creating a new Python file, `TorchNN.py`, and importing necessary PyTorch dependencies such as `NN`, `Adam`, and `dataloader` for building the neural network, optimizing it, and loading datasets.

As you can see, we address the same content as before, but we’ve cut things down to a single sentence summary.

## Share please 👉👈

If you have a chance to experiment with these prompts and find something cool (or just blow things up in a particularly spectacular way) we’d love to hear from you. Are we doing something terribly wrong and embarrassing with our prompting? Or something clever you hadn’t thought of? Let us know! You can tweet us at @ContendaCo.
