Gemini

Overview

Gemini integration is implemented using the Google Generative AI SDK, specifically using the 'gemini-pro' model. The implementation provides chat functionality without function calling support.

Implementation

Provider Setup

import { GoogleGenerativeAI, GenerativeModel } from '@google/generative-ai';

class GeminiProvider implements LLMProvider {
  private model: GenerativeModel;

  constructor() {
    const genAI = new GoogleGenerativeAI(process.env.GEMINI_API_KEY!);
    this.model = genAI.getGenerativeModel({ model: 'gemini-pro' });
  }
}

Message Generation

async generateResponse(
  messages: Array<{ role: string; content: string }>, 
  cleanContent: string
): Promise<LLMResponse> {
  const chat = this.model.startChat({
    history: messages.slice(0, -1).map(msg => ({
      role: msg.role === 'assistant' ? 'model' : 'user',
      parts: [{ text: msg.content }],
    })),
  });

  const result = await chat.sendMessage(
    messages[messages.length - 1].content
  );
  const response = await result.response;

  return {
    content: response.text(),
    totalTokens: undefined,
    toolCalls: undefined
  };
}
