For the past few years, we’ve applied core Google AI research and engineering to projects with positive societal impact, including forecasting floods, protecting whales and predicting famine. Artificial intelligence has incredible potential to address big social, humanitarian and environmental problems, but in order to achieve this potential, it needs to be accessible to organizations already making strides in these areas. So, the Google AI Impact Challenge, which kicked off in October 2018, was our open call to organizations around the world to submit their ideas for how they could use AI to help address societal challenges.

“Accelerating social good with artificial intelligence” sheds light on the range of organizations using AI to address big problems. It also identifies several trends around the opportunities and challenges related to using AI for social good. Here are some of the things  we learned—check out the report for more details.

AI is globally relevant 

We received 2,602 applications from six continents and 119 countries, with projects addressing a wide range of issue areas, from education to the environment. Some of the applicants had experience with AI, but 55 percent of not-for-profit organizations and 40 percent of for-profit social enterprises reported no prior experience with AI. 

Similar projects can benefit from shared resources

When we reviewed all the applications, we saw that many people are trying to tackle the same problems and are even using the same approaches to do so. For example, we received more than 30 applications proposing to use AI to identify and manage agricultural pests. The report includes a list of common project submissions, which will hopefully encourage people to collaborate and share resources with others working to solve similar problems.  

You don’t need to be an expert to use AI for social good

AI is becoming more accessible as new machine learning libraries and other open-source tools, such as Tensorflow and ML Kit, reduce the technical expertise required to implement AI. Organizations no longer need someone with a deep background in AI, and they don’t have to start from scratch. More than 70 percent of submissions, across all sectors and organization types, used existing AI frameworks to tackle their proposed challenge. 

Successful projects combine technical ability with sector expertise 

Few organizations had both the social sector and AI technical expertise to successfully design and implement their projects from start to finish. The most comprehensive applications established partnerships between nonprofits with deep sector expertise, and academic institutions or technology companies with technical experience.

ML isn’t the only answer 

Some problems can be addressed by using alternative methods to AI—and result in faster, simpler and cheaper execution. For example, several organizations proposed using machine learning to match underserved populations to legal knowledge and tools. While AI could be helpful, similar results could be achieved through a well-designed website. While we’ve seen the impact AI can have in solving big problems, you shouldn’t rule out more simple approaches as well. 

Global momentum around AI for social good is growing—and many organizations are already using AI to address a wide array of societal challenges. As more social sector organizations recognize AI’s potential, we all have a role to play in supporting their work for a better world. 

As AI-powered tools become increasingly prevalent, prompt engineering is becoming a skill that developers need to master. Large language models (LLMs) and other generative foundation models require contextual, specific, and tailored natural language instructions to generate the desired output. This means that developers need to write prompts that are clear, concise, and informative. 

In this blog, we will explore six best practices that will make you a more efficient prompt engineer. By following our advice, you can begin creating more personalized, accurate, and contextually aware applications. So let’s get started!

Tip #1: Know the model’s strengths and weaknesses

As AI models evolve and become more complex, it is essential for developers to comprehend their capabilities and limitations. Understanding these strengths and weaknesses can help you, as a developer, avoid making mistakes and create safer, more reliable applications.

For example, an AI model that is trained to recognize images of blueberries may not be able to recognize images of strawberries. Why? Because the model was only trained on a dataset of blueberry images. If a developer uses this model to build an application that is supposed to recognize both blueberries and strawberries, the application would likely make mistakes, leading to an ineffective outcome, and poor user experience.

It’s important to note that AI models have the ability to be biased. This is due to AI models being trained on data that is collected from the real world, and so it can reflect the inequitable power dynamics inherently rooted in our social hierarchy. If the data that is used to train an AI model is biased, then the model will also be biased. This can lead to problems if the model is used to make decisions that affect people by reinforcing societal biases. Addressing these biases is important to ensure that data is fair, promoting equality, and ensuring the responsibility of AI technology. Prompt engineers should be aware of training limitations or biases so they can craft prompts more effectively and understand what kind of prompting is even possible for a given model.

Tip #2: Be as specific as possible

AI models have the ability to comprehend a variety of prompts. For instance Google’s PaLM 2 can understand natural language prompts, multilingual text, and even programming codes like Python and JavaScript. Although AI models can be very knowledgeable, they are still imperfect, and have the ability to misinterpret prompts that are not specific enough. In order for AI models to navigate ambiguity, it is important to tailor your prompts specifically to your desired outcome. 

Let’s say you would like your AI model to generate a recipe for 50 vegan blueberry muffins. If you prompt the model with “what is a recipe for blueberry muffins?”, the model does not know that you need to make 50 muffins. It is thus unlikely to list the larger volume of ingredients you’ll need or include tips to help you more efficiently bake such a large number of muffins. The model can only go off the context that is provided. A more effective prompt would be “I am hosting 50 guests. Generate a recipe for 50 blueberry muffins.” The model is more likely to generate a response that is relevant to your request and meets your specific requirements.

Tip #3: Utilize contextual prompts

Utilize contextual information in your prompts to help the model gain an in-depth understanding of your requests. Contextual prompts can include the specific task you want the model to perform, a replica of the output you’re looking for, or a persona to emulate, from a marketer or engineer to a high school teacher. Defining a tone and perspective for an AI model gives it a blueprint of the tone, style, and focused expertise you’re looking for to improve the quality, relevance, and effectiveness of your output. 

In the case of the blueberry muffins, it is important to prompt the model using the context of the situation. The model might need more context than generating a recipe for 50 people. If it needs to be aware that the recipe must be vegan friendly, you might prompt the model by asking it to answer by emulating a skilled vegan chef. 

By providing contextual prompts, you can help ensure that your AI interactions are as seamless and efficient as possible. The model will be able to more quickly understand your request and it will be able to generate more accurate and relevant responses.

Tip #4: Provide AI models with examples 

When creating prompts for AI models, it is helpful to provide examples. This is because prompts act as instructions for the model, and examples can help the model to understand what you are asking for. Providing a prompt with an example looks something like this: “here are several recipes I like – create a new recipe based on the ones I provided.” The model can now understand the your ability and needs in order to make this pastry,

Tip #5: Experiment with prompts and personas

The way you construct your prompt impacts the model’s output. By creatively exploring different requests, you will soon have an understanding of how the model weighs its answers, and what happens when you interfuse your domain knowledge, expertise, and lived experience with the power of a multi-billion parameter large language model. 

Try experimenting with different keywords, sentence structures, and prompt lengths to discover the perfect formula. Allow yourself to step into the shoes of various personas, from work personas such as “product engineer” or “customer service representatives,” to parental figures or celebrities such as your grandmother, a celebrity chef, and explore everything from cooking to coding!

By crafting unique, and innovative, requests replete with your expertise and experience, you can learn which prompts provide you with your ideal output. Further refining your prompts, known as ‘tuning,’ allows the model to have a greater understanding and framework for your next output.

Tip #6: Try chain-of-thought prompting

Chain of thought prompting is a technique for improving the reasoning capabilities of large language models (LLMs). It works by breaking down a complex problem into smaller steps, and then prompting the LLM to provide intermediate reasoning for each step. This helps the LLM to understand the problem more deeply, and to generate more accurate and informative answers. This will help you to understand the answer better and to make sure that the LLM is actually understanding the problem. 

Conclusion

Prompt engineering is a skill that all workers, across industries and organizations, will need as AI-powered tools are becoming more prevalent. Remember to incorporate these five essential tips the next time you communicate with an AI model, so you can generate the accurate outputs that you desire. AI will forever continue to develop, constantly refining itself as we use it, so I encourage you to remember that learning, for mind and machine, is a never ending journey. Happy Prompting!

Over the decades, technology has helped us organize large amounts of physical information in ways that are streamlined, efficient, and easily accessible. Rows upon rows of encyclopedias are no longer needed; simply punch in or speak a query into Google Search and find numerous results at your fingertips. There’s no need to haul around cases of CDs or cassettes either, when you can access hundreds of thousands of songs on music streaming services. 

We wanted to bring that same level of accessibility to one specific type of publication: the printed car manual. Here’s how we shifted the paper manual to become an easy-to-access, voice-activated digital experience for owners of the all-new Sienna. It’s helped this resource become just as modern and useful as Toyotas themselves.

Putting cloud technology in the driver’s seat

Far too often, the printed car manual remains unused, collecting dust in the glove compartment—that is, until it’s needed during a roadside emergency or to solve the meaning of a mysterious light popping up on the dashboard. Even then, thumbing through hundreds of pages during high-stakes moments can be stressful. On top of that, these manuals can be expensive to print and update.

Digital versions, such as a PDF file, are a nice start. But, they’re often little more than reformatted flat documents. In poor visual conditions on the side of a road, the last thing a driver wants to do is squint at a phone or scroll through pages of tiny text. And similar to printed manuals, digital versions don’t facilitate ongoing, real-time conversations between drivers and automakers when it matters the most; they’re often only text and pictures, and at best, schematic drawings.

With that in mind, we set out to elevate and personalize the car manual by creating a voice-activated digital owner’s manual experience, all powered by Google Cloud. A voice-based assistant was the clear choice because, as it felt like the most intuitive, natural option, especially while driving. In fact, 51% of U.S. adults have used a voice assistant while driving, and 95% of all drivers expect to use a voice assistant in the next three years. 

We’re now putting this technology on the road by powering the Toyota Driver’s Companion for the all-new 2021 Toyota Sienna model. Accessible through the existing Toyota app, this companion provides real-time assistance, any time of the day. Drivers can ask questions and the companion will efficiently provide helpful answers in convenient ways, from voice to 3D walkthroughs and explorable environments. 

What a modern car manual should do

The Toyota Driver’s Companion has interactive features to help drivers discover the Sienna’s dashboard, set up the car’s interior and exterior appearance, better understand vehicle maintenance, and explore Dynamic Radar Cruise Control, Lane Departure Alert and other features. 

Here are a few other additional key features to call out within the Toyota Driver’s Companion: 

• An easily accessible virtual voice through the Toyota Driver’s Companion lets app users ask personal questions about their 2021 Sienna such as “what’s the height of my car?” and receive immediate answers either by voice, display or interactive input. 
• The manual automatically connects with the purchased vehicle’s VIN number to create a completely personalized experience, curated specifically for the driver. For example, if an unfamiliar light on the dashboard pops up, the Toyota Driver’s Companion can help identify the light’s meaning.
• Interactive hotspots throughout the vehicle’s interior let drivers explore the cabin virtually. Drivers can discover button functionalities, find specific dials, and learn more about car functions, such as how to slide seats or open doors, to become acclimated with their new vehicle.

To bring this experience to life, we tapped into some of our key Google Cloud solutions:

• APIs powered by Google Cloud artificial intelligence technology make accessing specific vehicle information easy and effortless, by leveraging Google’s natural language processing:
  • Google Cloud DialogFlow API serves as the decision tree that gives intelligence for both finding an answer for a question, i.e., how the Companion responds to the end user’s questions. 
  • One of our Text-to-Speech APIs—called Wavenet—creates the Companion’s realistic voice. 
  • And finally, our Speech-to-Text API “listens” to the user’s voice and finds the correct information to craft responses. That means a driver can ask a question multiple ways, and the Companion will still respond with the right answer.

We’re encouraging better consumer experiences by providing faster access to fresh information, in a natural, accessible format—voice. But these new voice-activated experiences aren’t only an opportunity to help out drivers; it’s also about strengthening connections between drivers, their vehicles, and automakers, too. 

Our hope is that through this information exchange, drivers can provide feedback on the most frequently misunderstood features, enabling OEMs to address questions early on. By understanding the most requested features, OEMs can also predict and inform driver questions about features. We’re incredibly excited to help make the driver’s experience more connected and helpful.
