Introducing Task-Specific and Jurassic-2 APIs

AI21 labs Jurassic

Announcing the release of Jurassic-2, the most recent iteration of AI21 Studio’s foundation models, which will revolutionise the area of artificial intelligence with its superior quality and additional features. Not only that, but AI21 Studio is also making available their task-specific APIs, which have superior plug-and-play reading and writing capabilities than those of AI21 Studio rivals.

The second generation of AI21 Studio foundation models, known as Jurassic-2 (or J2), has several new features and notable quality enhancements, such as zero-shot instruction-following, lower latency, and multi-language compatibility.

Developers may access industry-leading APIs for specialised reading and writing operations right out of the box with task-specific APIs.

For a closer look at each, continue reading.

AI21 Labs Jurassic 2


AI21 Studio is pleased to introduce their brand-new, cutting-edge Large Language Model family. Not only is J2 a complete upgrade over their previous generation models, Jurassic-1, but it also comes with additional features and capabilities that set it apart from the competition.

The Jurassic-2 family consists of instruction-tuned language models for Jumbo and Grande in addition to three different sized basic language models: Large, Grande, and Jumbo.

On Stanford’s Holistic Evaluation of Language Models (HELM), the industry standard for language models, Jurassic is already causing a stir. AI21 Labs evaluated J2 Jumbo using HELM’s official repository, and it currently ranks second (and is still rising). Not to mention, their Grande mid-sized model outperforms versions up to 30 times larger in size, allowing users to maximise production costs and speed without compromising quality.

In contrast to Jurassic-1, what’s new?

Higher calibre

Utilising state-of-the-art pre-training techniques and the most recent data (as of mid-2022), J2’s Jumbo model has achieved an 86.8% win-rate on HELM according to their internal assessments, firmly establishing it as a premier choice in the LLM arena.

Assign capabilities

The zero-shot instruction features of J2’s best-in-class models enable them to be guided using natural language without the need for examples. These features have been added to J2’s Grande and Jumbo models. As an illustration, consider this:

Multilingual Assistance

J2 is compatible with a number of non-English languages, such as Dutch, Spanish, French, German, Portuguese, and Italian.


J2’s models can outperform AI21 Studio earlier models by up to 30% in terms of latency.

You may now access every Jurassic-2 model on AI21 Studio playground and API. Here are some pointers and strategies for utilising the new Instruct models to get you going.

‍Task-Despecificated APIs

With the release of the Wordtune API set, AI21 Labs is also pleased to announce the debut of AI21 Studio’s new line of Task-Specific APIs, which will allow developers to access the language models behind AI21 Studio wildly successful consumer-facing reading and writing apps.

What makes task-specific APIs necessary?

AI21 Studio’s General Large Language Models are extremely strong and have been successfully customised by many of their clients to power their applications. But AI21 Studio have also seen that a lot of users have a lot of recurring use cases.

AI21 Studio’s ready-made, best-in-class language processing solutions enable developers to bypass many of the necessary model training and fine-tuning phases by giving them access to task-specific APIs.

Cutting-edge AI is used by Wordtune and Wordtune Read to help users with writing and reading chores, all while saving time and enhancing efficiency. AI21 Studio is making the AI engine underlying this range of award-winning apps available to developers with the introduction of Wordtune API, enabling them to fully utilise Wordtune’s features and incorporate them into their own apps:

  • Reword texts to suit any length, tone, or meaning by using paraphrasing.
  • Condense long texts into digestible, bite-sized chunks by summarising them.
  • Grammar and typo correction in real time is possible with Grammatical Error Correction (GEC).
  • Text Improvements: Learn how to make your writing more clear, more fluid, and more vocabulary-rich.
  • Text Segmentation: Divide lengthy texts into paragraphs that are each focused on a different subject.
