Just use Rovodev CLI. Gives you 20 million tokens for free per 24 hours and you can switch between sonnet 4 / gpt-5.

What is the catch?

> Beta technology disclaimer > Rovo Dev in the CLI is a beta product under active development. We can only support a certain number of users without affecting the top-notch quality and user experience we are known for providing. Once we reach this limit, we will create a waiting list and continue to onboard users as we increase capacity. This product is available for free while in beta.

Isn't this only available to a current Jira cloud/service subscription?
