AI21 Labs’ new developer platform offers instant access to our 178B-parameter language model, to help you build sophisticated text-based AI applications at scale

We are thrilled to announce the launch of AI21 Studio, our new developer platform where you can use our state-of-the-art Jurassic-1 language models to build your own applications and services. Jurassic-1 models come in two sizes, where the Jumbo version, at 178B parameters, is the largest and most sophisticated language model ever released for general use by developers. AI21 Studio is currently in open beta, allowing anyone to sign up and immediately start querying Jurassic-1 using our API and interactive web environment.

Our mission at AI21 Labs is to fundamentally reimagine the way humans read and write by introducing machines as thought partners, and the only way we can achieve this is if we take on this challenge together. We’ve been researching language models since our Mesozoic Era (aka 2017 😉). Jurassic-1 builds on this research, and it is the first generation of models we’re making available for widespread use.

Jurassic-1 models are highly versatile, capable of both human-like text generation, as well as solving complex tasks such as question answering, text classification and many others. Our models utilize a unique 250,000-token vocabulary which is not only much larger than most existing vocabularies (5x or more), but also the first to include multi-word tokens such as expressions, phrases, and named entities. Because of this, Jurassic-1 needs fewer tokens to represent a given amount of text, thereby improving computational efficiency and reducing latency significantly.

In order to help developers scale their applications beyond a proof-of-concept and efficiently serve production-scale traffic, AI21 Studio allows developers to train custom versions of Jurassic-1 models. Training a custom model is easy and requires as few as 50-100 training examples. Once trained, your custom model is served in AI21 Studio and immediately available for your exclusive use.

We created AI21 Studio to democratize access to cutting-edge AI technology. Using Jurassic-1 within AI21 Studio, you can quickly build text-based applications that rival those being dreamed up in the world’s biggest labs, even if you have no prior experience. We’ve been using AI21 Studio internally to power our own applications, and it has propelled our product development immensely. Now it’s your turn.
