Firebase AI Logic
Firebase AI Logic supports the latest Gemini model: gemini-3.1-pro-preview. You can directly access this model in your mobile or web app via either the Gemini Developer API or the Vertex AI Gemini API.
Note that the pay-as-you-go Blaze plan is required to access preview models (regardless of your Gemini API provider). Also, if you access the model via Vertex AI Gemini API, make sure to set the location in your request to global.

Cloud Storage for Firebase now requires Blaze pricing to keep access. Spark plan users with default buckets will lose console access and see 402/403 errors unless they upgrade. Upgrade to Blaze to regain access, with no‑cost usage still available.
Cloud Storage for Firebase
To continue using and accessing Cloud Storage for Firebase, your Firebase project must be on the Blaze pricing plan. These changes were first announced back in September 2024.
- What will happen: If you have an *.appspot.com default bucket and your Firebase project is still on the Spark pricing plan, then you'll lose console access to your bucket and your API calls will start returning 402 and 403 errors.
- What you need to do: To regain access and quality of service, upgrade to the pay-as-you-go Blaze pricing plan. No-cost usage is still available even on the Blaze pricing plan.
Learn more about these changes in our FAQs about changes to Cloud Storage for Firebase pricing and default buckets.

Firebase unlocks Cloud Logging export and full Observability compatibility for richer logs. Gemini 3 gains configurable thinking levels while App Testing caches and replays successful tests to boost stability. Also shipping Firebase CLI v15.4.0 and Unity SDK v13.7.0.
Crashlytics
You can now export your Crashlytics data and (optionally) Firebase sessions data to Cloud Logging. Once the data is exported, it's also available to the full Google Cloud Observability Suite, where you can filter your logs, build custom dashboards, set up custom alerts, and even export the data to other services. Learn more about how to set up export and check out a comprehensive list of what you can do with the exported data.
Firebase AI Logic
Firebase AI Logic now supports setting thinking levels for all Gemini 3 models. This configuration lets you control how much the model is allowed to think before returning a response, and it's helpful if reducing latency or cost is a priority.
