Important
A base model is the default AI model that {% data variables.product.prodname_copilot %} uses when no other models are enabled. The base model is automatically enabled for all {% data variables.copilot.copilot_business_short %} or {% data variables.copilot.copilot_enterprise_short %} accounts within 60 days after the model is designated as a base model.
When a new model is designated a base model, the following timeline applies:
| Announcement | Day 0 | {% data variables.product.github %} announces the new base model. |
| Upgrade window | Day 0 to Day 60 | Customers have 60 days to upgrade their IDE extensions to versions that support the new model. |
| Enablement | Day 60 | The new model is automatically enabled on all organizations and enterprises as the base model. |
Note
The base model has a 1x premium request multiplier on paid plans. For more information about multipliers, see AUTOTITLE.
Important
An LTS model is an AI model that {% data variables.product.github %} commits to supporting for an extended period of one year from its designation date. During that period, the model remains available, which allows users to build around the model without concern that it will be {% data variables.release-phases.closing_down %} unexpectedly.
