We’ve all used the web to seek for recipes – and we’ve all used the web to seek out recommendation as life throws new challenges at us. However what if, utilizing Generative AI, we might mix these tremendous powers and create a unusual private chef that may hearken to how your day went, how you feel, what you’re considering…after which create new, creative dishes with distinctive substances primarily based in your temper.

MoodFood is a playful tackle the standard recipe finder, appearing as a ‘Meals Therapist’ by asking customers how they really feel or how they wish to really feel, and producing recipes that vary from humorous takes on classics like ‘Heartbreak Soup’ or ‘Monday Blues Lasagne’ to real life recommendation ‘recipes’ for impressing your Mom-in-Legislation-to-be.

Within the instance above, the consumer inputs that they’re wired and have to impress their boyfriend’s mom, so our expertise recommends ‘My Future Mom-in-Legislation’s Hen Soup’ – a novel recipe and dish title that it has generated primarily based solely on the consumer’s enter. It then generates a graphic recipe ‘card’ and formatted substances / recipe checklist that might be used at hand off to a companion website for achievement.

Potential Use Circumstances are rooted in a novel tackle product discovery. Asking a consumer their temper might floor track suggestions in a music app, journey locations for a tourism companion, or precise recipes to order from Meals Supply apps. The template can be used as a discovery mechanism for eCommerce and Retail use circumstances. LLMs are opening a brand new world of exploration and potentialities. We’d love for our customers to see the facility of LLMs to mix identified substances, put it in a very completely different context like a consumer’s temper and invent new issues that customers can attempt!


We wished to discover how we might use the PaLM API in numerous methods all through the expertise, and so we used the API a number of occasions for various functions. For instance, producing a humorous response, producing recipes, creating structured codecs, safeguarding, and so forth.

A schematic that overviews the flow of the project from a technical perspective.

Within the present demo, we use the LLM 4 occasions. The primary prompts the LLM to be inventive and invent recipes for the consumer primarily based on the consumer enter and context. The second immediate codecs the responses json. The third immediate ensures the naming is suitable as a safeguard. The ultimate immediate turns unstructured recipes right into a formatted JSON recipe.

One of many jobs that LLMs will help builders is information formatting. Given any textual content supply, builders can use the PaLM API to form the textual content information into any desired format, for instance, JSON, Markdown, and so on.

To generate humorous responses whereas holding the responses in a format that we wished, we referred to as the PaLM API a number of occasions. For the enter to be extra random, we used a better “temperature” for the mannequin, and lowered the temperature for the mannequin when formatting the responses.

On this demo, we wish the PaLM API to return recipes in a JSON format, so we connect the instance of a formatted response to the request. That is only a small steerage to the LLM of the best way to reply in a format precisely. Nevertheless, the JSON formatting on the recipes is kind of time-consuming, which is likely to be a difficulty when dealing with the consumer expertise. To take care of this, we take the humorous response to generate solely a response message (which takes a shorter time), parallel to the JSON recipe era. We first render the response response after receiving it character by character, whereas ready for the JSON recipe response. That is to scale back the sensation of ready for a time-consuming response.

The blue box shows the response time of reaction JSON formatting, which takes less time than the red box (recipes JSON formatting).

If any job requires a little bit extra creativity whereas holding the response in a predefined format, we encourage the builders to separate this primary job into two subtasks. One for inventive responses with a better temperature setting, whereas the opposite defines the specified format with a low temperature setting, balancing the output.


Prompting is a method used to instruct a big language mannequin (LLM) to carry out a particular job. It includes offering the LLM with a brief piece of textual content that describes the duty, together with any related data that the LLM may have to finish the duty. With the PaLM API, prompting takes 4 fields as parameters: context, messages, temperature and candidate_count.

  • The context is the context of the dialog. It’s used to offer the LLM a greater understanding of the dialog.
  • The messages is an array of chat messages from previous to current alternating between the consumer (writer=0) and the LLM (writer=1). The primary message is at all times from the consumer.
  • The temperature is a float quantity between 0 and 1. The upper the temperature, the extra inventive the response can be. The decrease the temperature, the extra probably the response can be an accurate one.
  • The candidate_count is the variety of responses that the LLM will return.

In Temper Meals, we used prompting to instruct PaLM API. We informed it to behave as a inventive and humorous chef and to return unimaginable recipes primarily based on the consumer’s message. We additionally requested it to formalize the return in 4 elements: response, title, substances, directions and descriptions.

  • Reactions is the direct humorous response to the consumer’s message in a well mannered however entertaining means.
  • Identify: recipe title. We inform the PaLM API to generate the recipe title with well mannered puns and do not offend anymore.
  • Components: A listing of substances with measurements
  • Description: the meals description generated by the PaLM API

Third Social gathering Integration

The PaLM API provides embedding companies that facilitate the seamless integration of PaLM API with buyer information. To get began, you merely have to arrange an embedding database of companion’s information utilizing PaLM API embedding companies.

As soon as built-in, when customers seek for meals or recipe associated data, the PaLM API will search within the embedding area to find the perfect end result that matches their queries. Moreover, by integrating with the procuring API supplied by our companions, we will additionally allow customers to immediately buy the substances from companion web sites by means of the chat interface.


Swiggy, an Indian on-line meals ordering and supply platform, expressed their pleasure when contemplating the use circumstances made attainable by experiences like MoodFood.

“We’re excited in regards to the potential of Generative AI to remodel the way in which we work together with our clients and retailers on our platform. Moodfood has the potential to assist us go deeper into the services we provide, in a enjoyable and fascinating means”- Madhusudhan Rao, CTO, Swiggy

Temper Meals can be open sourced so Builders and Startups can construct on high of the experiences now we have created. Google’s Accomplice Innovation group will even proceed to construct options and instruments in partnership with native markets to increase on the R&D already underway. View the mission on GitHub right here.


We wish to acknowledge the invaluable contributions of the next folks to this mission: KC Chung, Edwina Priest, Joe Fry, Bryan Tanaka, Sisi Jin, Agata Dondzik, Sachin Kamaladharan, Boon Panichprecha, Miguel de Andres-Clavera.
