Model updates: what they mean for your work

Start with the task, then compare model specifications. Browse updates and sources below; before switching models, test results, costs and limits on your own work.

Reference data

Learning tip:For your first project, keep using a tool that meets the task. Before changing models in an engineering project, rerun your tests. We have not individually verified how these updates affect each tutorial.

You are viewing previously verified reference data, which may omit recent changes. Check the data date below.

Official release dates and catalog listing dates are labeled separately. A listing date is not an official release date. Tiers summarize catalog and public information; they are not our own cross-model benchmarks and may not apply to every task.

Refreshing requests data again; it does not mean the content was just published. If reading fails, the current data stays visible. Reference data is shown until online data has been read. You do not need to configure any keys.
