Firebase AI Logic

  • Firebase AI Logic now lets you run your own custom server-side scripts before and after every request. You implement these scripts as functions deployed to Cloud Functions for Firebase, and they'll trigger for every generateContent request that your app sends to the Gemini API via Firebase AI Logic. You can use this capability for many use cases, like moderating prompts, capping token usage, logging generations for analytics, redacting response content, etc. — all without modifying your client-side code.

SDK Releases

September 02, 2026

Firebase AI Logic

  • Firebase AI Logic supports the latest Gemini stable model gemini-3.8-flash. You can directly access this model in your mobile or web app via either the Gemini Developer API or the Agent Platform Gemini API (formerly Vertex AI).

    • If you're using the Gemini Developer API, accessing this model does not require the pay-as-you-go Blaze pricing plan.

    • If you're using the Agent Platform Gemini API (formerly Vertex AI) with the legacy "Vertex AI" initialization syntax, make sure to set the location in your request to global.

    • If you're migrating from previous models, note the following for this new model:

      • No support for MINIMAL thinking level: gemini-3.8-flash does not support the MINIMAL thinking level. If you set the thinking level to MINIMAL for this model, the request will fail with a 400 error.

      • Use thinking levels instead of thinking budgets: Thinking budgets have been supported by Gemini 3.x models for backwards-compatibility. However, starting with gemini-3.8-flash, they are strongly discouraged. If you haven't already, migrate to use thinking levels.

      • Removed support for several parameters: gemini-3.8-flash does not support the following parameters: temperature, top-K, top-P, frequency penalty, presence penalty, and candidate count.

        • Temperature, top-K, or top-P: All the general-use Gemini 3.x will ignore them.
        • Frequency penalty, presence penalty, and candidate count: Starting with gemini-3.7-flash, the request will fail with a 400 error.

        For more deterministic responses, define system instructions with explicit rules for your specific use case.

      • Prefilled model turn validation: Prefilling model turns is no longer supported. If the last non-empty turn in the request is a model turn, the API returns a 400 error.

Firebase CLI (v15.29.0)

  • The latest Firebase CLI (v15.29.0) is now available. This version adds support for the FIREBASE_DEBUG_PATH environment variable, adds -f, --force to firebase ext:migrate, and includes several fixes and improvements.

    To use the Firebase CLI in your development environment, set up or update the CLI.

September 01, 2026

Remote Config

  • Starting September 1, 2026, Remote Config offers a usage-based pricing structure based on daily fetch request volume. Every project includes a no-cost tier of up to 100,000 daily fetch requests, with pay-as-you-go pricing on the Blaze plan for usage exceeding this threshold. All features (including Personalization, Rollouts, and A/B Testing integration) remain included across both Spark and Blaze plans at no additional cost. To learn more about pricing plans, grace periods, and usage monitoring, see Pricing for Remote Config.

A/B Testing

August 31, 2026

Firebase AI Logic

  • Firebase AI Logic now supports the us and eu locations. When you use the Agent Platform Gemini API (formerly Vertex AI) (and depending on the model), you can choose where to access the model to meet your compliance, latency, availability, and durability requirements.

    Note that Firebase AI Logic defaults to the following locations:

    • When using the new "Agent Platform" initialization syntax: global
    • When using the legacy "Vertex AI" initialization syntax: us-central1

    Learn more about specifying the location for accessing the model.

August 27, 2026

Imagen models

  • All Imagen models shut down on August 17, 2026 (note that this shutdown date was extended from the previous June 30, 2026).

    To accommodate this shutdown, we've removed all Imagen APIs from the Firebase AI Logic SDKs and documentation.

    This shutdown date is applicable to both the Gemini Developer API (Google AI) and the Agent Platform Gemini API (formerly Vertex AI). As a replacement, you can migrate your apps to use a Gemini Image model (like one of the "Nano Banana" models).

    If you use Imagen models via Firebase AI Logic, you can migrate your apps to use a Gemini Image model to restore service. Models that are shut down are no longer accessible or supported by Google, and a request using a shutdown model name returns a 404 error.

Cloud Functions

Version 7.0.0 of the Firebase SDK for Cloud Functions contains breaking changes as well as new features and enhancements.

This release drops support for Node.js 16, requires TypeScript v5, and removes the deprecated functions.config() API.

Review these release notes carefully to avoid issues or outages.

Breaking changes

  • Minimum Node.js version is now 18. As of v7.0.0, the SDK requires a Node.js runtime of version 18 or newer. Support for Node.js 14 and 16 has been removed.
    • Impact: Functions using this SDK version fail to deploy or run on Node.js runtimes older than v18.
    • Action Required: Before upgrading the SDK, you must set the Node.js version to update your function's runtime environment to Node.js 18 or higher. We recommend using the latest Node.js LTS version supported by Cloud Functions.
  • The functions.config() API has been removed. Following the deprecation schedule announced in v6.0.0, runtime configuration with functions.config() has been removed entirely.
    • Impact: Calling this API now throws a runtime error and causes build time errors if you are using TypeScript. Any function relying on functions.config() fails at runtime.
    • Action Required: You must migrate from runtime configuration to environment variables using the params module.
  • TypeScript v5 is now required. The SDK has been upgraded from TypeScript v4.3 to v5.9 and now targets ES2022.
    • Impact: This may introduce new type-checking errors in your project if you are using an older version of TypeScript or if your code relies on older type definitions.
    • Action Required: Update your project's TypeScript version to v5.x and resolve any resulting type errors.
  • The Event interface, which defines the wire format for an event, has been changed to LegacyEvent. This change mitigates an api-extractor conflict caused by an open issue with Rushstack (#3581).
    • Impact: Very few users are likely to be affected, as this type represents the internal state of function triggers.
    • Action: If you rely on this type, update your code to use LegacyEvent instead.

  • Improved error handling for async handlers in the Emulator. We have improved how unhandled errors are processed in the Local Emulator Suite. Previously, an unhandled error or rejected Promise in an async onRequest handler would cause the request to hang until a platform timeout.

    • Impact: As of v7.0.0, these unhandled errors now correctly and immediately return a 500 Internal Server Error.
    • Action Required: This is a technical breaking change, as it changes error handling behavior. This provides faster, more accurate error feedback during local development. Ensure your error handling logic is correct and not reliant on the old timeout behavior.

  • The SDK is now published as both CommonJS (CJS) and ECMAScript Modules (ESM). This provides first-class support for modern bundlers (like Vite and esbuild) and native import syntax, which can lead to optimized function sources and smaller bundle sizes. The package.json exports map now properly resolves for both require and import.

  • This release adds a new function trigger for Firebase Data Connect (FDC), onMutationExecuted(). This allows you to execute functions in response to data mutations.
