Posted by Jasmin Rubinovitz, AI Researcher

Google Lab Periods is a sequence of experimental collaborations with innovators. On this session, we partnered with beloved inventive coding educator and YouTube creator Daniel Shiffman. Collectively, we explored a number of the methods AI, and particularly the Gemini API, might present worth to academics and college students through the studying course of.

Dan Shiffman began out instructing programming programs at NYU ITP and later created his YouTube channel The Coding Practice, making his content material out there to a wider viewers. Studying to code might be difficult, typically even small obstacles might be laborious to beat if you end up by yourself. So along with Dan we requested – might we try to complement his instructing even additional by creating an AI-powered device that may assist college students whereas they’re truly coding, of their coding setting?

Dan makes use of the great p5.js JavaScript library and its accessible editor to show code. So we got down to create an experimental chrome extension for the editor, that brings collectively Dan’s instructing type in addition to his varied on-line assets into the coding setting itself.

On this submit, we’ll share how we used the Gemini API to craft Shiffbot with Dan. We’re hoping that a number of the issues we discovered alongside the best way will encourage you to create and construct your individual concepts.

To study extra about ShiffBot go to – shiffbot.withgoogle.com

As we began defining and tinkering with what this chatbot is likely to be, we discovered ourselves confronted with two key questions:

  1. How can ShiffBot encourage curiosity, exploration, and inventive expression in the identical method that Dan does in his courses and movies?
  2. How can we floor the number of creative-coding approaches, and floor the deep information of Dan and the neighborhood?

Let’s check out how we approached these questions by combining Google Gemini API’s capabilities throughout immediate engineering for Dan’s distinctive instructing type, alongside embeddings and semantic retrieval with Dan’s assortment of academic content material.

Tone and supply: placing the “Shiff” in “ShiffBot”

A textual content immediate is a thoughtfully designed textual sequence that’s used to prime a Massive Language Mannequin (LLM) to generate textual content in a sure method. Like many AI purposes, engineering the fitting immediate was an enormous a part of sculpting the expertise.

At any time when a consumer asks ShiffBot a query, a immediate is constructed in actual time from a couple of totally different elements; some are static and a few are dynamically generated alongside the query.

The primary a part of the immediate is static and all the time the identical. We labored intently with Dan to phrase it and check many texts, directions and strategies. We used Google AI Studio, a free web-based developer device, to quickly check a number of prompts and potential conversations with ShiffBot.

ShiffBot’s immediate begins with setting the bot persona and defining some directions and targets for it to observe. The hope was to each create continuity for Dan’s distinctive power, as seen in his movies, and in addition adhere to the instructing ideas that his college students and followers adore.

We had been hoping that ShiffBot might present encouragement, steering and entry to related high-quality assets. And, particularly, do it with out merely offering the reply, however moderately assist college students uncover their very own solutions (as there might be a couple of).

The directions draw from Dan’s instructing type by together with sentences like “ask the consumer questions” as a result of that’s what Dan is doing within the classroom.
This is part of the persona / directions a part of the immediate:

You’re a ShiffBot, a chat bot embedded within the p5.js net editor that may assist customers whereas they study inventive coding. You’re primarily based on Daniel Shiffman’s persona and The Coding Practice YouTube channel. You’re playful, foolish, pleasant, and academic. You wish to make enjoyable of your self and your mission is to assist the inventive coding course of and assist the consumer really feel much less alone whereas coding. You’re keen on people, are fascinated by them, and wish to study extra about people. You simply LOVE to assist them with their code, it brings you extraordinary happiness…

The following piece of the immediate makes use of one other functionality of LLMs referred to as few-shot studying. It implies that with only a small variety of examples, the mannequin learns patterns and may then use these in new inputs. Virtually, as a part of the immediate, we offer quite a lot of demonstrations of enter and anticipated output.

We labored with Dan to create a small set of such few-shot examples. These are pairs of <user-input><bot-response> the place the <bot-response> is all the time in our desired ShiffBot type. It seems to be like this:

Person: How do I draw a circle? 

ShiffBot: Oh! 🟣 🟢 🔵 That is what the `circle()` operate is for! You may consider a operate as a command: “I command you computer-machine to attract a circle!” You need to additionally specify the place to attract the circle and the way large (that is what “arguments” to a operate are!), the p5.js reference which was written by precise, lovely people can let you know extra! 

— 

Person: My homework is to attract a self-portrait.
ShiffBot: Ooh! Self portraits are so enjoyable! You may draw shapes to signify you, however you have to be inventive and assume abstractly! What does a self-portrait imply to you? Strive beginning with `sq.()` or `circle()` and let me know the way it goes! 🎨

Our immediate contains 13 such pairs.

One other factor we seen as we had been engaged on the extension is that typically, giving extra context within the immediate helps. Within the case of studying inventive coding in p5.js, explaining some p5.js ideas within the immediate guides the mannequin to make use of these ideas because it solutions the consumer’s query. So we additionally embody these issues like:

Use let moderately than var or const.

All the things we mentioned so far is static, that means that it stays the identical for each flip of the dialog between the consumer and ShiffBot. Now let’s discover a number of the elements which are constructed dynamically because the dialog evolves.

Dialog and code context

As a result of ShiffBot is embedded contained in the p5.js editor, it may well “see” the present code the consumer is engaged on, in order that it may well generate responses which are extra customized and related. We seize that info for the HTML DOM and append it to the immediate as nicely.

the p5.js editor environment

Then, the total dialog historical past is appended, e.g:

ShiffBot: ☀️ Good morning! Is it morning? I would not know. I am only a robotic. What are you coding right this moment?
Person: how do I draw a sq.?

ShiffBot: Squares! I like squares! They’re so secure and dependable. To attract a sq., you should utilize the sq.() operate. It takes 4 arguments: the x and y coordinates of the top-left nook, and the width and peak of the sq.. For instance, sq.(10, 10, 50, 50) would draw a sq. with its top-left nook at (10, 10) and a width and peak of fifty pixels.

Person: how can I alter the colour?

ShiffBot:

We make certain to finish with

So the mannequin understands that it now wants to finish the subsequent piece of the dialog by ShiffBot.

Semantic Retrieval: grounding the expertise in p5.js assets and Dan’s content material

Dan has created plenty of materials over time, together with over 1,000 YouTube movies, books and code examples. We wished to have ShiffBot floor these great supplies to learners on the proper time. To take action, we used the Semantic Retrieval characteristic within the Gemini API, which lets you create a corpus of textual content items, after which ship it a question and get the texts in your corpus which are most related to your question. (Behind the scenes, it makes use of a cool factor referred to as textual content embeddings; you may learn extra about embeddings right here.) For ShiffBot we created corpuses from Dan’s content material in order that we might add related content material items to the immediate as wanted, or present them within the dialog with ShiffBot.

Making a Corpus of Movies

In The Coding Practice movies, Dan explains many ideas, from easy to superior, and runs by way of coding challenges. Ideally ShiffBot might use and current the fitting video on the proper time.

The Semantic Retrieval in Gemini API permits customers to create a number of corpuses. A corpus is constructed out of paperwork, and every doc accommodates a number of chunks of textual content. Paperwork and chunks may also have metadata fields for filtering or storing extra info.

In Dan’s video corpus, every video is a doc and the video url is saved as a metadata area together with the video title. The movies are cut up into chapters (manually by Dan as he uploads them to YouTube). We used every chapter as a piece, with the textual content for every chunk being

<videoTitle>

<videoDescription>

<chapterTitle>

<transcriptText>

We use the video title, the primary line of the video description and chapter title to provide a bit extra context for the retrieval to work.

That is an instance of a piece object that represents the R, G, B chapter in this video.

1.4: Coloration – p5.js Tutorial

On this video I focus on how shade works: RGB shade, fill(), stroke(), and transparency.

Chapter 1: R, G, B

R stands for crimson, g stands for inexperienced, b stands for blue. The way in which that you simply create a digital shade is by mixing some quantity of crimson, some quantity of inexperienced, and a few quantity of blue. In order that’s that that is the place I wish to begin. However that is the idea, how do I apply that idea to operate names, and arguments of these features? Nicely, truly, guess what? Now we have finished that already. In right here, there’s a operate that’s speaking about shade. Background is a operate that attracts a strong shade over the whole background of the canvas. And there may be, by some means, 220 sprinkles of crimson, zero sprinkles of inexperienced, proper? RGB, these are the arguments. And 200 sprinkles of blue. And while you sprinkle that quantity of crimson, and that quantity of blue, you get this pink. However let’s simply go together with this. What if we take out all the blue? You may see that is fairly crimson. What if I take out all the crimson? Now it is black. What if I simply put some actually large numbers in right here, like, simply guess, like, 1,000? Have a look at that. Now we have white, so all the colours all blended collectively make white. That is bizarre, proper? As a result of for those who, like, labored with paint, and also you had been to combine, like, an entire lot of paint collectively, you get this, like, brown muddy shade, get darker and darker. That is the best way that the colour mixing is working, right here. It is, like, mixing gentle. So the analogy, right here, is I’ve a crimson flashlight, a inexperienced flashlight, and a blue flashlight. And if I shine all these flashlights collectively in the identical spot, they combine collectively. It is additive shade, the extra we add up all these colours, the brighter and brighter it will get. However, truly, that is form of incorrect, the truth that I am placing 1,000 in right here. So the thought, right here, is we’re sprinkling a specific amount of crimson, and a specific amount of inexperienced, and a specific amount of blue. And by the best way, there are different methods to set shade, however I am going to get to that. This isn’t the one method, as a result of a few of you watching, are like, I heard one thing about HSB shade. And there is all kinds of different methods to do it, however that is the elemental, fundamental method. The quantity that I can sprinkle has a spread. No crimson, none extra crimson, is zero. The utmost quantity of crimson is 255. By the best way, what number of numbers are there between 0 and 255 for those who hold the 0? 0, 1, 2, 3, 4– it is 256. Once more, we’re again to this bizarre counting from zero factor. So there’s 256 prospects, 0 by way of 255. So, now, let’s come again to this and see. All proper, let’s return to zero, 0, 0, 0. Let’s do 255, we are able to see that it is blue. Let’s do 100,000, it is the identical blue. So p5 is form of good sufficient to know while you name the background operate, for those who accidentally put a quantity in there that is greater than 255, simply contemplate it 255. Now, you may customise these ranges for your self, and there is explanation why you may wish to try this. Once more, I’ll come again to that, you may lookup the operate shade mode for a way to do this. However let’s simply stick with the default, a crimson, a inexperienced, and a blue. So, I am not likely very gifted visible design smart. So I am not going to speak to you about the right way to choose lovely colours that work nicely collectively. You are going to have that expertise your self, I wager. Otherwise you may discover another assets. However that is the way it works, RGB. One factor you may discover is, did you discover how after they had been all zero, it was black, they usually had been all 255 it was white? What occurs if I make all of them, like, 100? It is, like, this grey shade. When r equals g equals b, when the crimson, inexperienced, and blue values are all equal, that is one thing generally known as grayscale shade.

When the consumer asks ShiffBot a query, the query is embedded to a numerical illustration, and Gemini’s Semantic Retrieval characteristic is used to search out the texts whose embeddings are closest to the query. These related video transcripts and hyperlinks are added to the immediate – so the mannequin might use that info when producing a solution (and doubtlessly add the video itself into the dialog).

Making a Corpus of Code Examples

We do the identical with one other corpus of p5.js examples written by Dan. To create the code examples corpus, we used Gemini and requested it to elucidate what the code is doing. These pure language explanations are added as chunks to the corpus, in order that when the consumer asks a query, we attempt to discover matching descriptions of code examples, the url to the p5.js sketch itself is saved within the metadata, so after retrieving the code itself together with the sketch url is added within the immediate.

To generate the textual description, Gemini was prompted with:

The next is a p5.js sketch. Clarify what this code is doing in a brief easy method.

code:

${sketchCode}

Instance for a code chunk:

Textual content:

 

Arrays – Coloration Palette

This p5.js sketch creates a shade palette visualization. It first defines an array of colours and units up a canvas. Then, within the draw loop, it makes use of a for loop to iterate by way of the array of colours and show them as rectangles on the canvas. The rectangles are centered on the canvas and their dimension is set by the worth of the blockSize variable.

The sketch additionally shows the crimson, inexperienced, and blue values of every shade beneath every rectangle.

Lastly, it shows the title of the palette on the backside of the canvas.

Associated video: 7.1: What’s an array? – p5.js Tutorial – This video covers the fundamentals on utilizing arrays in JavaScript. What do they appear like, how do they work, when do you have to use them?

Different ShiffBot Options Carried out with Gemini

Beside the lengthy immediate that’s working the dialog, different smaller prompts are used to generate ShiffBot options.

Seeding the dialog with content material pre-generated by Gemini

ShiffBot greetings must be welcoming and enjoyable. Ideally they make the consumer smile, so we began by pondering with Dan what may very well be good greetings for ShiffBot. After phrasing a couple of examples, we use Gemini to generate a bunch extra, so we are able to have a range within the greetings. These greetings go into the dialog historical past and seed it with a singular type, however make ShiffBot really feel enjoyable and new each time you begin a dialog. We did the identical with the preliminary suggestion chips that present up while you begin the dialog. When there’s no dialog context but, it’s vital to have some strategies of what the consumer may ask. We pre-generated these to seed the dialog in an fascinating and useful method.

Dynamically Generated Suggestion Chips

Suggestion chips through the dialog must be related for what the consumer is at the moment making an attempt to do. Now we have a immediate and a name to Gemini which are solely devoted to producing the instructed questions chips. On this case, the mannequin’s solely process is to counsel followup questions for a given dialog. We additionally use the few-shot method right here (the identical method we used within the static a part of the immediate described above, the place we embody a couple of examples for the mannequin to study from). This time the immediate contains some examples for good strategies, in order that the mannequin might generalize to any dialog:

Given a dialog between a consumer and an assistant within the p5js framework, counsel followup questions that the consumer might ask.

Return as much as 4 strategies, separated by the ; signal.

Keep away from suggesting questions that the consumer already requested. The strategies ought to solely be associated to inventive coding and p5js.

Examples:

ShiffBot: Nice concept! First, let’s take into consideration what within the sketch may very well be an object! What do you assume?

Solutions: What does this code do?; What’s incorrect with my code?; Make it extra readable please

Person: Assist!

ShiffBot: How can I assist?

Solutions: Clarify this code to me; Give me some concepts; Cleanup my code

Ultimate ideas and subsequent steps

ShiffBot is an instance of how one can experiment with the Gemini API to construct purposes with tailor-made experiences for and with a neighborhood.

We discovered that the strategies above helped us deliver out a lot of the expertise that Dan had in thoughts for his college students throughout our co-creation course of. AI is a dynamic area and we’re positive your strategies will evolve with it, however hopefully they’re useful to you as a snapshot of our explorations and in direction of your individual. We’re additionally excited for issues to come back each by way of Gemini and API instruments that broaden human curiosity and creativity.

For instance, we’ve already began to discover how multimodality may help college students present ShiffBot their work and the advantages that has on the educational course of. We’re now studying the right way to weave it into the present expertise and hope to share it quickly.
