🔥 VertexAI for Firebase

We are excited to announce 0-day support for Vertex AI for Firebase with the introduction of the new langchain_firebase package.

If you need to call the Vertex AI Gemini API directly from your mobile or web app, you can now use the ChatFirebaseVertexAI class. This class is specifically designed for mobile and web apps, offering enhanced security options against unauthorized clients (via Firebase App Check) and seamless integration with other Firebase services. It supports the latest models (gemini-1.5-pro and gemini-1.5-flash) as well as tool calling.

await Firebase.initializeApp();
final chatModel = ChatFirebaseVertexAI(
  defaultOptions: ChatFirebaseVertexAIOptions(
    model: 'gemini-1.5-pro-preview-0514',
  ),
);

Check out the documentation and the sample project (a port of the official firebase_vertexai sample).

⚡️ Google AI for Developers (Upgrade)

ChatGoogleGenerativeAI and GoogleGenerativeAIEmbeddings have been upgraded to use version v1beta of the Gemini API (previously v1), which supports the latest models (gemini-1.5-pro-latest and gemini-1.5-flash-latest).

ChatGoogleGenerativeAI now includes support for tool calling, including parallel tool calling.

Under the hood, we have migrated the client from googleai_dart to the official google_generative_ai package.

✨ OpenAI (Enhancements)

You can already use the new OpenAI's GPT-4o model. Additionally, usage statistics are now included when streaming with OpenAI and ChatOpenAI.

🦙 Ollama

The default models for Ollama, ChatOllama, and OllamaEmbeddings have been updated to llama3. ChatOllama now returns a finishReason. OllamaEmbeddings now supports keepAlive.

🛠️ openai_dart

The Assistant API has been enhanced to support different content types, and several bug fixes have been implemented.
The batch API now supports completions and embeddings.

🔧 ollama_dart

The client has been aligned with the Ollama v0.1.36 API.
