Current Model Upgrades + New Command Beta Model | Cohere

--- title: Current Model Upgrades + New Command Beta Model slug: changelog/improvements-to-current-models-new-beta-model-command type: added createdAt: 'Tue Nov 08 2022 16:43:50 GMT+0000 (Coordinated Universal Time)' hidden: false description: >- Introducing new and improved Medium and XLarge models, plus a Command model for precise responses to commands. New & Improved Medium & Extremely Large The new and improved `medium` and `x-large` outperform our existing generation models on most downstream tasks, including summarization, paraphrasing, classification, and extraction, as measured by our internal task-based benchmarks. At this time, all baseline calls to `x-large` and `medium` will still route to previous versions of the models (namely, xlarge-20220609 and medium-20220926). To access the new and improved versions, you’ll need to specify the release date in the Playground or your API call: `xlarge-20221108` and `medium-20221108`. Older versions of the models (xlarge-20220609 & medium-20220926) will be deprecated on December 2, 2022. NEW Command Model (Beta) We’re also introducing a Beta of our new Command model, a generative model that’s conditioned to respond well to single-statement commands. Learn more about how to prompt `command-xlarge-20221108`. You can expect to see `command-xlarge-20221108` evolve dramatically in performance over the coming weeks.
