- Tool-enabled assistants: Create assistants that execute functions, call external APIs (like Maps Embed), run code, and ground answers with Google search or other tools for accurate, actionable outputs.
- Media generation and content creation: Generate and edit images or short video snippets using integrated media models (Imagen, Veo) for marketing, creative workflows, or automated asset creation.
- Enterprise deployment via Vertex AI: Move prototypes from Studio into managed, scalable production deployments on Google Cloud Vertex AI for enterprise-grade reliability and compliance.
- Rapid prototyping of LLM-powered apps and agents
- Fine-tuning base models for domain-specific tasks
- Building spatially-aware applications (2D/3D reasoning, video event exploration)
- Integrating LLMs with external services (maps, embeds, other APIs) via function calling
