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.
