New Firebase AI Logic features to explore - September 2025 updates

As of August 2026, the Vertex AI Gemini API has been renamed the Agent Platform Gemini API, alongside expanded Firebase AI Logic capabilities for building AI-powered applications. New features include Gemini Live API support through the no-cost Gemini Developer API on Web, Flutter, Unity, and Android for interruptible voice conversations; client-side Imagen image generation and editing on Android and Flutter; and hybrid on-device web inference that can switch between Gemini Nano and cloud models. Firebase has also extended AI monitoring to the Gemini Developer API, providing visibility into requests, latency, errors, and token usage, while Gemini 2.5 thinking-model controls allow developers to set reasoning budgets and inspect thought summaries for optimization. Additional App Check limited-use tokens offer shorter-lived protection ahead of planned one-time-token support, and Firebase plans further improvements to APIs, coding workflows, prompt security, and privacy.
