Specifically, it concerns the set of AI provider dependencies declared in the project.

Describe the thing to improve

Currently, all major AI providers are included as regular dependencies, making them required for every installation. This creates unnecessary overhead: I may not use most of them, and installing so many dependencies increases the risk of version conflicts and dependency failures.

I recommend making all third-party AI providers (e.g. @ai-sdk/..., @aihubmix/ai-sdk-provider, @gitlab/gitlab-ai-provider, @mymediset/sap-ai-provider, ollama-ai-provider-v2, workers-ai-provider) optional peer dependencies instead of required dependencies. This would let users choose only the providers they need, reducing bloat and improving overall stability.

Describe the solution (optional)

Consider refactoring the package.json so AI providers are removed from required dependencies and added as optional peerDependencies instead. This could be documented clearly to help users install only what they need for their use case.
