Transitioning to Jurassic-2: Important Updates on Model Retirements and Pricing Changes

12 months ago by Yotam Shinan

We have a few updates to share regarding our Jurassic models at AI21 Studio:

  1. Jurassic-1 Models Retirement: As of June 1st, 2023, all Jurassic-1 models will be retired. We encourage users to transition to our more powerful Jurassic-2 models and train new custom models based on Jurassic-2 as soon as possible.
  2. Jurassic-2 Models Pricing: Starting from May 1st, 2023, the usage of Jurassic-2 models will no longer be free. You can find detailed information about pricing at this link.
  1. Free Custom Model Training: Although the usage of Jurassic-2 models is now at cost, the training of custom models on Jurassic-2 will remain free until June 1st, 2023.

To ensure a smooth transition, please update your code and switch to Jurassic-2 models, including updating the URL in your API requests. For example, replace:
api.ai21.com/studio/v1/j1-grande/complete
with:
api.ai21.com/studio/v1/j2-grande/complete

For new custom models, consider adopting the same name as the previous version with a "-j2" suffix to track your upgrades.

As always, feel free to reach out with any questions or concerns on our Discord server or through our usual channels.

Thank you for being a part of our community, and we look forward to witnessing your innovative work with Jurassic-2!
