. Key areas of inquiry include:

1. Financial details of payments made by AI companies to cloud providers
2. Existence of exclusive rights to license AI models
3. Potential plans for acquisitions of AI partners by tech giants

1. Possibility of cloud service providers acquiring their AI partners
2. AI providers giving advance notice of important decisions to cloud partners
3. Restrictions on AI companies launching new models independently of cloud providers 1
