Model is not assignable to type "LanguageModelV1"
Issue
I have updated the AI SDK and now I get the following error: Type 'SomeModel' is not assignable to type 'LanguageModelV1'.
Note
Similar errors can occur with EmbeddingModelV4 as well.
Background
Sometimes new features are being added to the model specification. This can cause incompatibilities with older provider versions.
Solution
Update your provider packages and the AI SDK to the latest version.
