Pegasus 1.2 requests rejected; Pegasus 1.5 is now the default model

Use Pegasus 1.5 for all video analysis. The platform now rejects any request that specifies Pegasus 1.2, and uses Pegasus 1.5 by default when you omit the model_name parameter.

This change affects the following:

• Analysis: The /analyze and /analyze/tasks endpoints accept only Pegasus 1.5.
• Index creation: You cannot create an index with Pegasus 1.2.
• Existing indexes: You can no longer add videos to an index that has only Pegasus 1.2 enabled. When you add videos to an index that has both Marengo and Pegasus 1.2 enabled, the platform indexes them with Marengo only.

Actions required

Migrate your integration to Pegasus 1.5. Follow the steps in the Migration guide.
