Google Lab Classes 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, may present worth to lecturers and college students in the course of the studying course of.
Dan Shiffman began out educating programming programs at NYU ITP and later created his YouTube channel The Coding Practice, making his content material obtainable to a wider viewers. Studying to code might be difficult, typically even small obstacles might be exhausting to beat if you end up by yourself. So along with Dan we requested – may we try to complement his educating even additional by creating an AI-powered software that may assist college students whereas they’re truly coding, of their coding atmosphere?
On this put up, we’ll share how we used the Gemini API to craft Shiffbot with Dan. We’re hoping that a number of the issues we realized alongside the way in which will encourage you to create and construct your individual concepts.

As we began defining and tinkering with what this chatbot is perhaps, we discovered ourselves confronted with two key questions:
- How can ShiffBot encourage curiosity, exploration, and inventive expression in the identical method that Dan does in his lessons and movies?
- 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 educating model, 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 Giant Language Mannequin (LLM) to generate textual content in a sure method. Like many AI purposes, engineering the fitting immediate was a giant a part of sculpting the expertise.
Every time a person asks ShiffBot a query, a immediate is constructed in actual time from a couple of completely 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 carefully with Dan to phrase it and take a look at many texts, directions and methods. We used Google AI Studio, a free web-based developer software, to quickly take a look at a number of prompts and potential conversations with ShiffBot.
ShiffBot’s immediate begins with setting the bot persona and defining some directions and objectives for it to observe. The hope was to each create continuity for Dan’s distinctive power, as seen in his movies, and likewise adhere to the educating rules that his college students and followers adore.
We had been hoping that ShiffBot may present encouragement, steerage and entry to related high-quality sources. And, particularly, do it with out merely offering the reply, however reasonably assist college students uncover their very own solutions (as there might be a couple of).
The directions draw from Dan’s educating model by together with sentences like “ask the person 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:
The following piece of the immediate makes use of one other functionality of LLMs known as few-shot studying. It signifies 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 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 model. It seems like this:
Our immediate contains 13 such pairs.
One other factor we observed 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 rules within the immediate guides the mannequin to make use of these rules because it solutions the person’s query. So we additionally embody these issues like:
Every thing we mentioned thus far is static, that means that it stays the identical for each flip of the dialog between the person and ShiffBot. Now let’s discover a number of the elements which might be 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 person is engaged on, in order that it may well generate responses which might be extra customized and related. We seize that info for the HTML DOM and append it to the immediate as effectively.

Then, the total dialog historical past is appended, e.g:
We make sure that 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 sources and Dan’s content material
Dan has created a whole lot of materials through the years, together with over 1,000 YouTube movies, books and code examples. We wished to have ShiffBot floor these fantastic 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 might be most related to your question. (Behind the scenes, it makes use of a cool factor known as textual content embeddings; you possibly can learn extra about embeddings right here.) For ShiffBot we created corpuses from Dan’s content material in order that we may 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 may 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 incorporates 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 subject together with the video title. The movies are break 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
We use the video title, the primary line of the video description and chapter title to offer 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.
When the person 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 may use that info when producing a solution (and probably 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 person 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:

Different ShiffBot Options Carried out with Gemini
Beside the lengthy immediate that’s operating the dialog, different smaller prompts are used to generate ShiffBot options.
Seeding the dialog with content material pre-generated by Gemini
ShiffBot greetings needs to be welcoming and enjoyable. Ideally they make the person smile, so we began by considering with Dan what might be good greetings for ShiffBot. After phrasing a couple of examples, we use Gemini to generate a bunch extra, so we will have a range within the greetings. These greetings go into the dialog historical past and seed it with a singular model, 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 essential to have some strategies of what the person may ask. We pre-generated these to seed the dialog in an fascinating and useful method.
Dynamically Generated Suggestion Chips
Suggestion chips in the course of the dialog needs to be related for what the person is at the moment attempting to do. We now have a immediate and a name to Gemini which might be solely devoted to producing the steered questions chips. On this case, the mannequin’s solely process is to recommend followup questions for a given dialog. We additionally use the few-shot approach right here (the identical approach we used within the static a part of the immediate described above, the place we embody a couple of examples for the mannequin to be taught from). This time the immediate contains some examples for good strategies, in order that the mannequin may generalize to any dialog:

Last 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 methods 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 subject and we’re certain your methods will evolve with it, however hopefully they’re useful to you as a snapshot of our explorations and in the direction of your individual. We’re additionally excited for issues to return each by way of Gemini and API instruments that broaden human curiosity and creativity.
For instance, we’ve already began to discover how multimodality might help college students present ShiffBot their work and the advantages that has on the educational course of. We’re now studying weave it into the present expertise and hope to share it quickly.

Whether or not for coding, writing and even considering, creators play a vital position in serving to us think about what these collaborations may appear like. Our hope is that this Lab Session offers you a glimpse of what’s attainable utilizing the Gemini API, and conjures up you to make use of Google’s AI choices to deliver your individual concepts to life, in no matter your craft could also be.
